EnvironmentalSealing Overview








Electromagnetic Compatibility(EMC)


Electrical

The electrical requirements are covered by measurementsmade to ascertain the level of attenuation requiredto fulfil the figures laid down in the appropriatespecification over a specified frequency band.

The data given in the catalogue outlines the typicalattenuation versus frequency of the various materialswhen correctly fitted. These figures are corroborated by

independent tests.

Mechanical

The mechanical considerations are of the utmostimportance in the fitment of shielded gaskets.

The design of an EMI shielded enclosure should beundertaken as if the gasketing will be required. If it is

determined at a later stage that a particular gasket isnot required it is easy to leave this out. If no provisionfor the gasket is made and then later required themodification to implement a gasket can be time

consuming and costly.

The most effective shielding is provided when acontinuous metal to metal contact is achieved. The metalsurfaces of any enclosure flange are never 100% flat

unless machined to very high tolerances. The function ofthe gasket is to take up any differences which may existbetween the surfaces. The type of gasket material and

thickness is thus selected according to the toleranceswith which the enclosure or panel is fabricated.

To ensure metal to metal contact the design shouldincorporate, wherever possible, a means to preventthe over compression of the gasket and thus ensure

evenness of pressure.

It is very important when fitting conductive gaskets that

all contact surfaces be free from contamination and behighly conductive. The surfaces must therefore be freeof paint, greases etc. and thoroughly cleaned prior to

fitment of the gasket.

Chemical

Two dissimilar metals in the presence of an electrolytee.g., sea water. will act as a battery and create a flow of

electric current. This effect can cause corrosion and couldaffect the resistivity of the gasket material reducing itsefficiency. In order to minimise or prevent galvanic actionit is important to select compatible metals.

Environmental

Often equipment will need to operate in conditionswhere the ingress of moisture would be hazardous tothe correct functioning of the system. To prevent this, an

extra non conductive gasket acting as an environmentalseal can be incorporated into the design ofthe enclosure.

A more practical solution is to use an EMI shieldedgasket which incorporates an environmental seal.

There are a variety of types available.

Technical Specifications

Material Selection

Kemtron manufacture conductive elastomersusing four standard highly conductive fillers in bothsilicone and fluorosilicone variants, all have slightlydifferent attributes:

Conductive fillers available for Silicone andFluorosilicone

• Nickel Plated Graphite A high quality cost effective commercial material withincreased use in the military markets. Easily extruded

or molded. SNG FR grade to UL94 V0 and meetsthe requirements of BS 6853:1999 Incorporatingamendment No1. Low smoke and low toxicity.

• Silver Plated Aluminium An excellent grade high performance materialwidely used for higher frequency applications in the

commercial and military markets. Lighter in weightthan some other materials.

• Silver Plated Copper This material offers excellent RFI/EMI shieldingperformance across the frequency spectrum, butcomes at a higher price and with increased weight.

• Nickel This product has largely been replaced by NickelGraphite but is still widely used in military andaerospace applications. Fluorosilicone has better

aging properties than the silicone. A good performerat lower frequencies but also heavier than someother materials.

Silicone (VMQ)Silicone rubber is used because the end use requires amaterial that retains its elastomeric properties over a very

wide range of temperatures and does not degrade dueto the presence of oxygen and ozone.

Silicone elastomers do have weaknesses in their

properties and behavior. In comparison with otherelastomers their tensile, tear and abrasion properties aresignificantly poorer, however, they do not decay as the

temperature is increased and above 150˚C they become

on the whole better.

The swelling and chemical resistance of silicones iscomparable to those of chloroprene rubber, they are not

affected by aliphatic oils however they swell in napthenicand are attacked by hot aromatic oils.

Silicones main weakness is to hydrolytic attack and

decomposition especially to steam between 120˚C and140°C, they are also susceptible to attack by acidsand alkalis.

Fluorosilicone (FVMQ)Fluorosilicone is used because it overcomes the formers

chemical resistance and swelling weaknesses whilstretaining on the whole the excellent high temperatureproperties. FVMQ however still suffers from attack by

high temperature steam and hydrolysis by both acidsand alkalis.

Properties of elastomers that can be

measured and how they impact onselection of the appropriate material

for gasket/sealing purposes

HardnessHardness is a measure of the degree of indentationwhen an indenter of known geometry is placed on theelastomeric surface under a known constant force for

a fixed time. The different scales used Shore A and IRHDare defined by the form of the indenter, applied loadand time of reading after indenter application. In a

standard elastomer there is reasonable agreementbetween observed hardness and Young’s Modulus (E).In the case of conductive elastomers this relationship isnot so clear cut since the elastomer acts more as a binder

for the filler and the hardness appears to have a rule ofmixtures response.

Tensile strength and elongation at breakTensile strength and elongation at break are obtainedfrom the same standard dumbbell shaped test-piece

punched from a moulded sheet of rubber of knownthickness. By use of tensile test equipment fitted withan extensometer a stress v strain response curve can be

obtained and a judgement of the stresses and strainsthat can be made on the material during service made.

Tear

The tearing properties of a material are obtained usingtensile test equipment and a standard test piece of

known dimensions. Tests are carried out in tensionand the results reported in terms of load required perdistance moved by the tear tip.

Compression set

Compression set (or more correctly permanent set aftercompression to a fixed strain) should not be confusedwith either Creep or Stress Relaxation. The test wasoriginally conceived as a measure of state of cure.

The test basically involves compressing a cylinder ofmaterial to a fixed strain and leaving it for a knowntemperature for a fixed time. The compression is

removed, the cylinder allowed to recover over a fixedtime and the height re-measured. The value recordedbeing the percentage difference according to the

equation below;

Compression set at Constant Strain = to – tr x 100to – ts

Where

to is the original thickness

tr is the thickness after recovery

ts is the deflection applied (thickness of shim)

Hence, the test as originally conceived would be carriedout on test pieces cured for varying times at a fixed

temperature and the correct cure determined from

where the compression set value was found to be aminimum. Although the original purpose of the testhas been superseded by modern rheometers the test

continues to be used. The reason for this being the

belief that the test gives an indication of creep whichcan be seen below is not strictly true. Since the test is

an amalgamation of that used to assess creep andstress relaxation.

Creep also known as cold flowCreep is defined as the change in strain with time whilstthe elastomer is held under a constant stress. This stress

can take the form of compression, tension and/or shear.

In terms of how creep applies to a seal or gasket,this is dependent on whether it is constrained or non-

constrained. In the non-constrained environment thestrain within the elastomer will increase with time until

in theory the stress within the elastomer reaches aminimum. The elastomer seal/gasket will compress andspread out. In the constrained environment the seal/ gasket will conform to the groove allowed and the

creep arrested.










Stress relaxation

Stress relaxation is defined as the change in stress withtime whilst the elastomer is held under a constant strain.

Consider that you have a seal that during installation iscompressed by 10% of its original thickness. To obtain

this 10% compression requires 100 MPa, and you canconsider that the elastomer is exerting 100 MPa in returnand the seal would be able to retain internal and externalforces of 100 MPa. However, with time and ageing the

stress exerted by the elastomeric seal can decay i.e. itmay only exert 90 MPa yet still be compressed by 10%.

The paragraph above describes the reality of StressRelaxation in compression the other two modes of

tension or shear can also be measured.

Certain schools of thought recommend that stress

relaxation issues can be overcome by increasing theinitial compression the seal / gasket is taken to by 25%in the expectation that stress relaxation will occur and

the operational force will be that required. This approachobviously assumes that the seal/gasket will be able towithstand the extra strain and the seal/gasket behavior

to the extra stress remains the same. Consideration mustalso be given to whether it is retained in a groove or freeto take up a natural form on deflection.

Compression deflectionThis test is carried out using a disc of the gasket/seal

material of a known thickness and diameter towhich is applied a load equivalent to 100 psi andthe deflection measured.

Accelerated ageing testsIn general any of the above tests can be carried outon test samples either aged or cut from test sheetswhich have been exposed to air ageing at an elevated

temperature. Such tests may give an indication ofhow the material will perform in the long term in theservice environment.

Standard Tests Specific to

Conductive Elastomers

Volume resistivityIn this test a sample of the conductive Elastomer whosedimensions are known is put under compression to aknown strain. The difference between the known

applied current is compared to that flowing throughthe Elastomer and the resistivity of the Elastomer.

Volume resistivity after extension/breakThis test is the same as that for volume resistivity exceptthat the sample is punched from the central strip of a

dumbbell that has been stretched to break and thenallowed to recover for thirty minutes.

This test gives an indication of the behavior of thematerial if it is stretched during installation or is re-used

during servicing.

Dynamic volume resistivity

In this test the variation in the volume resistivity ismeasured whilst a sample of known dimensions is putunder a fixed load. The load is then oscillated around

this fixed point by a known amount over a range offrequencies and the volume resistivity recorded.

The purpose of this test is to give an indication as tohow the seal/gasket will perform in service when thevibrations from equipment operations are imposed

upon it.

Conductive Silicone & Fluorosilicone

Elastomers – Product Handling & Storage

Conductive elastomer products are expected to providea service life of many years. However, if the product is tobe stored, certain factors may have a detrimental effect.

Kemtron recommend that the following precautions arecarefully observed to ensure product longevity:

HandlingThese materials should not be subjected to stretching ineither storage or installation otherwise the conductive

particles may disperse in the rubber, resulting indegradation of the shielding performance. In additionmaterials should be handled using cotton gloves to

prevent surface contamination. Extra care must be usedwhen fitting gaskets into channels, especially “O” rings.

The product should be eased into the final groove shapefrom each end or opposite diagonals, working slowlyinwards or round the outside. It must not be placed in atone end and simply pushed in along the length, this will

stretch the gasket and leave excess material. If in doubtplease contact us for our recommendations.

Storage temperatureIt is recommended that the product be stored at normalambient temperatures.

Exposure to light & UVExposure to any UV source (i.e artificial or natural light)should be avoided if possible. It should be kept storedin light proof, sulphur free packaging.

Method of storageThe material must be stored without any stretching

or crushing. It is best kept in light proof, sulphur freepolythene bags or light proof, sulphur free boxes.

Contact with other materialsThe product should not be allowed to comeinto contact with Solvents, oils & greases, PVC,

any material containing sulphur, dissimilar rubbersor metal containers.








Conductive Elastomers:Extrusions


Product Overview

Kemtron manufacture a wide variety of profiles from our standard tooling.We are also able to produce to your exact requirement with minimaltooling cost.

Extruded profiles are available in continuous, cut lengths or fabricated toyour requirements, such as rectangles by vulcanizing the joints. This processuses the same conductive polymer compound. Ensuring complete electricalconductivity is maintained across the joints. Please see ‘O’ ring section.

Design Considerations• When selecting a profile it is important to give

attention to the mechanical design of your product.Round and D section seals should ideally be mounted

in a suitably sized channel or groove.• If the gasket is to fit in a groove. It is important that

the gasket size chosen does not overfill the groove,

when using solid sections you should ensure thatthe groove cross sectional area is a minimum of5% greater than the proposed gasket cross section.

See grove design data.• Attention must also be paid to the closing force

required to compress the gasket to the working

height required.• Self adhesive backing usually only partially covers

an area of extrusions and is non-conductive.

This is offered as an assembly aid only.

Gaskets in Grooves

For the typical electronic enclosure, groove mounted

gaskets are better than surface mounted gasketsbecause when the gasket is compressed in the groovethe two mating flanges can come into contact with each

other thereby enhancing the EMC performance with theadvantage of the groove acting as a compression stop

and therefore protecting the gasket from damage at thesame time.

Solid and Hollow Gaskets in Grooves

Because solid and tubular style gaskets, when

compressed, cannot change their volume the groovehas to be larger in width to accommodate the changein shape, otherwise severe gasket damage can be

caused when the flanges are fixed together. Thiscan result in loss of compression on the gasket and“compression set” occurring. This will give a reduction

of shielding effectiveness, coupled with the possibilityof environmental leakage. The groove width shouldbe from 5% to 35% larger than the gasket width,

but this is dependent upon the gasket profile being used.For example, a round section gasket has less volumethan a square section gasket of the same diameter/

width.

The important factor is that in the worst case of high

tolerances on the gasket size versus low tolerances onthe groove size is that when the gasket is compressed byboth flanges, it fills the available space by no more than

100%, i.e.: the volume of the accommodating groovewith both flanges touching should be equal to, but beno less than the volume of the gasket cross section.

Knife Edge into Grooves

with Tubular Gaskets

Large applications, such as cabinets, may use a tubular

type gasket fitted into a groove and the mating flangeknown as a knife edge. The knife edge plunges into thegasket causing the seal. With tubular gaskets the knife

edge collapses the gasket rather than compressing it.The knife edge should not penetrate the gasket by morethan 50% of its diameter or there may be a danger of

the gasket being unable to recover due to the excesspressure applied by the knife edge.

The above cross sectional area groove sizes allow for thefree movement of the gasket when being compressed.

This method of calculation ensures that the volume ofthe gasket does not exceed that of the groove whenfully compressed, resulting in groove overfill. This also

minimises the amount of compression force required toachieve a good RFI/EMI seal.

It is important to note that when designing in an EMCgasket, that the principles of O ring design for pressure

sealing do not apply. The groove depth dimension isthe most important, as it is this that limits the gasketcompression. The groove width has no maximumdimension and is only there for gasket location purposes.

Tighter groove dimensions using volume calculationsmay be employed to enhance environmental sealing.However this will increase the compression forces

required.

The above calculations are based on reducing the depthof the groove by a given compression % and increasingthe width by the same amount less 5% EG: 20%reduction in depth 15% increase in width.

When choosing a tube section as a gasket it is

recommended that consideration be given to the lowercompression forces, making sure that there is enoughresilience in the gasket to ensure a good RFI/EMI seal.

In these cases it is sometimes better to use the volumegroove size calculation, with the groove side wallsoffering support for the tube.

Because there are so many variables with tube cross

sections it is difficult to give precise information onthis subject. Kemtron are able to supply samples forevaluation purposes.

It is also important to consider the tolerances of thegasket and the groove.

Internal Bend Radius

The minimum internal bend radius of a solid cord gasket is 1.5 x cross

section of cord.

The minimum internal bend radius of a tube gasket where the id of the

tube is no greater than 30% of the cross section is 2.5 x cross section

of tube.

Conductive Elastomers:‘O’ Rings


Product Overview

Kemtron’s experience in the manufacture of ‘O’ rings is vast, our preferredmethod of production is extruded and jointed. We have a huge selection ofvulcanizing tools to suit our standard extrusions.

The jointing process uses the same conductive polymer compound ensuringcomplete electrical conductivity is maintained across the joints.Moulded versions are available if specifically requested.

Both silicone & fluorosilicone with all varieties of conductive fillers are

available for the manufacture of ‘O’ rings.Advantages Of Vulcanised ‘O’ Rings• Cost effective.

• No tooling costs.• Reduced lead times.

• Better surface finish (zero flash).

• Allows hollow sections to be used for lowercompression force.

• Custom lengths easily produced.

• Tight tolerances on developed length andcross section.

• Vulcanised ‘O’ rings with a ID as small as 10mm

depending on cord diameter.

Design Considerations• When selecting a profile it is important to give

attention to the mechanical design of your product.Round and D section seals should ideally be mountedin a suitably sized groove.

• If the gasket is to fit in a groove. It is important thatthe gasket size chosen does not overfill the channel,when using solid sections you should ensure that

the groove cross sectional area is a minimum of 5%greater than the proposed gasket cross section.

• Attention must also be paid to the closing force

required to compress the gasket to the workingheight required.

Conductive Elastomers:Sheet & Flat Gaskets


Product Overview

Flat gaskets are produced from moulded sheet using economic rule dies.Larger gaskets can be cut from moulded or fabricated picture frames.This option has the advantage of saving material and allows larger gasketsto be produced economically. Fabricated frames use either extruded ormoulded flat section that is joined by vulcanizing the polymer. The sameconductive polymer compound is used to vulcanize the joints ensuringcomplete electrical conductivity is maintained across the joint.

This process has allowed Kemtron to produce gaskets up to 2 meters’ long,with the same mechanical and electrical integrity as is found in a single partgasket cut from sheet. This method of manufacture often offers costsavings over cutting from sheet with subsequent loss of waste material.

Our in-house production facilities are suitable for prototype, short andmedium production runs, up to commercial quantities.

Design Considerations

• It is important that this material is not over-

compressed. If the design of the equipment does notallow for any mechanical method of preventing over-

compression, the gasket should be fitted with built-incompression limiters, either metal stops fitted to thegasket, or metal collars fitted into each fixing hole.

• The material is not suitable in sliding applications.

• Recommended compression: 10% to 20%.• Self adhesive backing (conductive or non-conductive)

is offered as an assembly aid only.

• Fluorosilicone: self-adhesive backing is notrecommended for use with this type of elastomer.

• Minimum material width should not be less than 2mm

or at least the material thickness in any part of thegasket. If this cannot be achieved around fixing holesconsider using a slot. Particular attention is required if

specifying compression collars in holes.

• Consideration must be given to compression forces,

hole centres, size and number of fixings and rigidityof mating flanges.

• Integral compression stops or collars should be

considered to limit over compression if externalcontrols cannot be applied. Recommended minimumsheet thickness for integral limits is 1.5mm.

Surface Mounted Gaskets

With surface mounted elastomeric gaskets, the aimshould be to limit the compression of the gasket tobetween 10% and 20%. 10% being the minimumwith a solid silicone style of gasket. (Some form of

compression stop or limit is essential with surfacemounted gaskets to prevent over compression).

Compression stops can be built into many styles of

gasket, or made as an integral part of the flange. Theirheight should equal that of the maximum compressedheight of the gasket. Compression stops fitted into

gaskets can be in the form of collars or washers so thatfixing bolts can pass through them or as solid studslocated either side of a fixing bolt.

The thickness of the gasket for a known application canbe calculated as follows e.g. Consider a gasket whichcan be compressed between 10% and 25% to be usedon flanges which are not perfectly flat, i.e. the flanges

without gaskets touch at some points and leave gapsin others. Since the gasket will compress between10% and 25% we will require 25% compression at the

high points and 10% at the low points (the “gaps”).The greatest gap is therefore 15% of the gasketthickness. If that gap is 0.45mm, then a gasket of

3.0mm thickness is required

This is fine in theory provided that the flanges do

not “bow” when placed under load. To overcomeflange distortion, fixings may need to be added,the number of which will be determined by the flangestiffness/rigidity.

Product Overview

Kemtron Form-in-Place (FIP) Elastomer compounds are directly dispensedonto component hardware or enclosure via a pressurised fluid dispensingsystem on a numerically controlled XYZ table to form a gasket for RFI/EMIshielding and/or environmental seal for dust and moisture. The dispensingmachine deposits the gasket by following a pre-determined CNC path toprovide accuracy and repeatability.


The process advantages are• Component is integrated with EMI shielding

and/ or environmental gasket.• Materials are one-component room curable.• Assembly time is reduced as gasket is

included on component.• Rapid prototyping.• Low setup costs.• Smaller gasket land required.• Variety of materials available to optimise

shielding and galvanic compatibility.• No material waste.• Excellent EMI shielding.

• Can be applied to metal and plasticcomponents.








Product Overview (Continued)


Applications

Suited to applications where small, intricate gasketproles are required, such as on multi-compartmentlabyrinth housings with minimum gasket land area

where traditional larger types of gasket are not suitable.This process also negates the assembly costs associatedwith traditional gaskets as the Form-in-Place gasket

becomes an integral part of the housing or enclosure.The process is suitable for depositing on both metaland metallised plastic components/housing.

AvailabilityKemtron can dispense FIP gaskets directly onto the

customer’s free issue hardware or can procure thecomponent hardware thereby reducing the customer’s

supply base. Kemtron can also supply FIP compounds insyringes or Semco cartridges for the customer’s own use.

Form- in-Place gasket materials include:

For RFI/EMI Shielding• Silver plated copper lled silicone.

• Silver plated aluminium lled silicone.• Silver plated nickel lled silicone.• Nickel coated graphite lled silicone.

For Environmental Sealing only• Unlled silicone.


• To achieve optimum EMI shielding performancethe component surface on which the gasket is tobe deposited must be highly conductive as lowcontact resistance is required between the two.

Chromate finishes on aluminium must be conductive.• The gasket height can be specied between 0.4mm

to 2.0mm, gasket width will typically be 1.5x the

gasket height. General tolerance is +/-0.1mm.• Recommended gasket compression is between 20%

and 30%. Over-compression can damage the gasket

and as compression stops cannot be incorporatedinto the gasket they should be designed into thecomponent hardware.

• Gasket path for the deposition can be determined

from a sample part, drawings or CAD les.

Production CapabilityTo meet the varying demands of customer requirementsKemtron has developed its own CNC Form-in-Place

dispenser. FIP gasketing work has become a regularfeature of our production work and we are able toprovide a reliable, accurate and quick response to even

high volume orders.

(including luer lock types) for accurate, controlledapplication. Larger sizes of 55ml, 170ml & 310mlare available on request.

Electrically Conductive Epoxy Adhesives

• Very high bond strength.• Room temperature cure.• Flexible – degree is variable by adjusting mix ratio.

• Extremely resistant to fracture.

• Safe for use with most common substrates –non tarnishing / discolouring.

• Excellent resistance to ageing.• Wide service temperature range – retains strength

and conductivity at extremes of temperature.

• Stable – low bond (joint) resistance throughtemperature cycling.

• Kembond Epoxy can be supplied in either 4ml or 10ml

double syringe packs. The material is automaticallydispensed in the correct 50:50 ratio. Alternatively, thismaterial can be supplied in separate syringe barrels

where variable mix ratios are to be used.

Design considerations

• Service conditions.• Compatibility with substrate.• Galvanic compatibility.

• Rigid or exible bond.

Instructions for UseSurfaces should be clean dry and sound i.e. free from

loose material. It is recommended that areas to bebonded are cleaned using a suitable solvent prior toapplying the sealant.

To ensure the highest level of electrical or shieldingperformance it is essential that the surfaces to bebonded have a low contact resistance. This means that

materials that have a naturally occurring oxide layersuch as aluminium alloys may need to be lightly abradedand cleaned directly prior to bonding.

The adhesive mix ratio for epoxy may be varied in order

to modify the cured properties. For most applicationswe would recommend a 50:50 mix ratio that willresult in a cured adhesive with a small degree ofexibility, high strength and reasonably good low

temperature performance.

Increasing the proportion of hardener up to arounda maximum of 125:50 will result in a cured adhesive

with a relatively high degree of exibility along withimproved low temperature performance but otherphysical properties will be reduced.

Ensure the two components are thoroughly mixed.Once mixed this material has a working (or pot) life ofapproximately one hour (depending on the ambient

temperature) and may be transferred to a syringe forprecise application if required.

Assemble parts as soon as possible and certainly within15-30 minutes of adhesive application.

In most cases parts may be handled after 12 hours butavoid stressing the joint until full cure has been achieved.

Cure rate may be controlled by means of temperature.The adhesive will fully cure within 3 hours at 60°C.

If curing at elevated temperatures be careful to avoidexcessive adhesive outow due to the uncured adhesiveviscosity reducing during the curing process.

Excess material should be removed by means of a spatulaor similar implement. Smaller traces of the uncuredmaterial may be removed by wiping with a lint free cloth

damped with methylated spirit, isopropyl alcohol or MEKtaking care to observe the safety precautions required inusing ammable/harmful solvents of this type.

A priming agent is available for treating someinconsistent or difficult to bond surfaces. Please contactus for further information.

Oriented Wires in Silicone& Fluorosilicone Rubber

Product Overview

A flat, sheet material, comprising a solid or sponge silicone rubber,embedded with Monel or Aluminium metal wires orientated perpendicularto its surface. Excellent RFI/EMI/EMP shielding performance is achieved asthe material has a wire density of 140 wires/cm2 in solid silicone and100 wires/cm2 in sponge silicone providing an environmental and RFI/EMIseal when clamped between two metallic surfaces.

The wires are crimped to aid compression and are chemically bonded

to ensure their retention in the silicone. They will also penetrate most oxidelayers, ensuring a low contact resistance path when suitably compressed.This material also demonstrates EMP survivability.


Application• A good solution for achieving RFI/EMI/EMP and

Environmental sealing in a single gasket.• Ideal for use as access panels, seals, connector

gaskets etc.

• Good conformity to allow for uneven surfaces.

AvailabilityKemtron is able to offer a wide variety of options as

the material is cut in-house from large blocks, up to228mm wide, using our high-speed slicer, enabling

us to offer all thicknesses (subject to material type)to suit the customer’s exact design requirement.

• Die- cut gaskets.• Large fabricated gaskets.

• Virtually any at shape can be produced.• Sheet material.• Strip material available in continuous lengths.

• Self-adhesive backing to allow for easy assembly.• Can be tted with compression limit stops or collars.

• Small gaskets can be punched in one operation,keeping production costs to a minimum.

• Larger gaskets can be produced cost effectively andwithout the constraint of sheet size limitation fromstrips of material fabricated into the required nished

shape, thus avoiding waste material from the centreof the gasket.

• A uorosilicone version is available for use in

environments where fuels / oils / hydraulic fluids

and other contaminants are present.• Solid Silicone, for use in applications where

higher compression forces allow for betterenvironmental sealing.

• Sponge Silicone requiring lower compression forces.











• It is important that this material is not over-compressed. If the design of the equipment doesnot allow for any mechanical method of preventingover-compression, the gasket should be tted withbuilt-in compression limiters, either metal stops

tted to the gasket, or metal collars tted intoeach xing hole.

• There is no need for a conductive connection where

strips are joined as the wires forming the EMC contactrun vertically though the material; a waterproof sealis achieved by vulcanising the join with silicone.

• The material is not suitable for frequent openingor sliding applications.

• Recommended compression: Solid – 15% to 20%,

Sponge – 15% to 25%.• Fluorosilicone: self-adhesive backing is not

recommended for use with this type of elastomer.

• Minimum material width should not be less than2mm or at least the material thickness in any part ofthe gasket. If this cannot be achieved around xing

holes consider using a slot. Particular attention isrequired if specifying compression collars in holes.

• Particular consideration must be given to compression

forces (see data in this section) hole centres, size andnumber of xings and rigidity of mating anges.

Production CapabilitiesKemtron holds large stocks of raw material blocks,

which are cut in-house on one of the most advancedslicing machines in Europe, and which enables us toproduce bespoke gaskets economically and on time.

We are able to cut sheets up to 228mm wide by 900mmlong, whilst holding a parallel tolerance of +/-0.2mmand can apply self-adhesive backing prior to die cutting

and or fabrication.

Gasket fabrication is a routine feature of our work,

enabling us to produce economic gaskets by maximisingmaterial usage, without the limitations of sheet width.Joins are vulcanised using a silicone compound and over-

compression stops or collars can be tted to the gasketif required.

Our in-house production facilities are suitable for

prototype, short and medium production runs, up tocommercial quantities.

Product Overview

A composite of metal wire mesh impregnated with an elastomer, creating ahighly conductive and resilient gasketing material for EMI/RFI shieldingand environmental sealing applications.

Choose from:• Woven aluminium wire, expanded aluminium or expanded Monel sheet,

impregnated with an elastomer filler – Silicone, fluorosilicone or synthetic rubber or;• Expanded Monel sheet without elastomer fller.

The conductive metallic surfaces of the material provide an excellent low resistance contact

whilst under the correctly designed conditions the rubber component ensures effective dustand moisture sealing.

The exposed metallic points on the woven product, where the weave of the wire overlaps,create approximately 80 contacts per cm2 whilst the raised edge on the expanded sheet productcreates approximately 20 contacts per cm2.


ApplicationsProvides an economic approach to gasketing flat surfaceswhere unevenness does not exceed 0.10mm and/orwhere material thickness constraints occur.

Particularly suited to small thin gaskets such as MIL type

connectors etc. Other thin gaskets can be made in-house

using specialist cutting methods and the material canalso be supplied as continuous sheet for customer’s own

production purposes.

Fluorosilicone versions are suitable for applicationswhere fuels/oils/hydraulic fluids and other contaminants

are present.

AvailabilityCan be supplied as

• Continuous roll, 305mm wide, in 0.5mm and 0.8mmthickness (see specification).

• Standard connectors.

• Bespoke gaskets made to customer’s specifcation.











• These materials are not suitable for joining orfabricating. Gaskets are only available as a single part.• Gasket size is limited to 300mm in width with

minimal constraints on length.• Minimum material width should not be less than

2.5mm in any part of the gasket. If this cannot be

achieved around fixing holes, consider using a slot.• As these materials are of a solid nature they

give very little compression and should therefore

be used between ridged flat surfaces with acombined flatness tolerance of 0.1mm maximum.Compression limiting stops are therefore not

normally required with these materials.• Self-adhesive backing is not recommended.

Production Capability

Kemtron holds large stocks of raw materials which,together with our in-house facilities using precisionlaser cut rule dies, enables us to produce bespoke

gaskets economically and on time, whether forprototype, short and medium production runs orfor commercial quantities.

Knitted Wire MeshOver an Elastomer Core


Product Overview

This product is a knitted wire mesh over an elastomer core such asneoprene or silicone cellular profile or tube. Usually this consists of 2 layersof knitting over the elastomer core but small sections 1.5mm diameterrequiring only 1 layer. The knitted mesh is then formed into the selectedprofile making a continuous gasket strip which is flexible and compressibleand which makes an excellent RFI/EMI/EMP gasket.

Application

In addition to making an excellent EMI/RFI/EMP shield

between two metallic surfaces the choice of wire meshmaterial available also allows for a good galvanic match

with mating flanges, thereby limiting the possibilityof corrosion between gasket and flange. Further, theelastomer core of the gasket allows it to be compressed

using low to medium force conforming to unevensurfaces and recovering well after use.

• Groove gaskets such as ‘O’ rings.

• Due to its resiliency and low compression force,ideal for use in situations where repeated openingand closing operations are necessary.

Availability

• In continuous lengths.• Cut to length.• Fabricated into nished gaskets.• Variety of proles and sizes.

• Fabricated gaskets.• Selection of wire to meet galvanic

compatibility requirements.

• Large selection of elastomer cores are availableto meet conditions such as temperature range,compression set, compression force.

• Although round or rectangular cross sections are

the most commonly used, other sectionscan be made to custom designs.

• Where EMP protection is needed, a minimum of

7 layers is recommended. Additional layers canalso be added depending on the application ofthe equipment and degree of shielding required.

• Self adhesive backing is not recommended withthis version of mesh.


• Consideration should be given to the termination of

cut mesh ends. Sometimes loose wires are evidentafter cutting. Kemtron are experts at mesh termination

however if you choose to cut the mesh yourself loosewires can be avoided by:– Dipping the end in glue,

– Spot welding the cut end. – Sewing the cut mesh end.

• Compression forces required to allow good contact.

Also the rigidity of the host metalwork.• Galvanic compatibility. Select from a choice or wire.• Water and moisture sealing is not possible with this

product. However, it does offer a limited dust seal.

Knitted Wire Meshwith an Environmental Seal


ApplicationThis type of gasket is very suitable where a high level

of shielding is required along with an environmentalseal. Provides an economic approach to combinationRFI/EMI/EMP and environmental sealing.

• Suitable for gaps with large tolerances.• Door seals.• Panel seals.

• Due to its resiliency and low compression force,ideal for use in situations where repeated openingand closing operations are necessary.

Availability• Continuous lengths up to 10 mtrs long.

• Fabricated gaskets to customer’s drawings.• Can be tted with compression limit stops

or collars.

• Easily assembled using the optional selfadhesive backing.

• A broad range of sizes available.• A large range of materials to suit many

RFI/EMI/EMP and climatic conditions including NBC.• Large fabricated gaskets can be

produced economically.

• UL ame retardant approved materials arealso available.

Design Considerations• It is important that this material is not

over-compressed. If the design of the equipmentdoes not allow for any mechanical method ofpreventing over-compression, the gasket should be

fitted with built-in compression limiters, either metalstops fitted to the gasket, or metal collars fittedinto each fixing hole.

• When specifying die cut gaskets minimum materialwidth should not be less than 2mm or at least thematerial thickness in any part of the gasket. If this

cannot be achieved around fixing holes consider usinga slot. Particular attention is required if specifyingcompression collars in holes.

• Particular consideration must be given to compressionforces hole centres, size and number of fixings andrigidity of mating flanges.

• Consideration should be given to the termination ofcut mesh ends. Sometimes loose wires are evidentafter cutting. Kemtron are experts at mesh termination

however if you choose to cut the mesh yourself loosewires can be avoided by:– Dipping the end in glue.

– Spot welding the cut end. – Sewing the cut mesh end.

• Galvanic compatibility. Select from a choice or wire.

Surface Mounted Gaskets

With surface mounted elastomeric gaskets, the aimshould be to limit the compression of the gasket tobetween 10% and 20%. 10% being the minimumwith a solid silicone style of gasket. (Some form of

compression stop or limit is essential with surfacemounted gaskets to prevent over compression).

Compression stops can be built into many styles of

gasket, or made as an integral part of the flange. Theirheight should equal that of the maximum compressedheight of the gasket. Compression stops fitted into

gaskets can be in the form of collars or washers so thatfixing bolts can pass through them or as solid studslocated either side of a fixing bolt.

The thickness of the gasket for a known application canbe calculated as follows e.g. Consider a gasket whichcan be compressed between 10% and 25% to be usedon flanges which are not perfectly flat, i.e. the flanges

without gaskets touch at some points and leave gapsin others. Since the gasket will compress between10% and 25% we will require 25% compression at the

high points and 10% at the low points (the “gaps”).The greatest gap is therefore 15% of the gasketthickness. If that gap is 0.45mm, then a gasket of

3.0mm thickness is required

This is fine in theory provided that the flanges do

not “bow” when placed under load. To overcomeflange distortion, fixings may need to be added,the number of which will be determined by theflange stiffness/rigidity.

Product Overview

This product is manufactured from a synthetic polyester or nylon yarn whichis plated to give electrical conductivity over the surface of the fibre and thenwoven in a traditional way so as to produce a conductive cloth. The cloth isthen slit and wrapped over a soft polyether polyurethane foam core in arange of profiles and results in an economically priced conformableconductive gasket strip suitable for many applications.


ApplicationsThe versatility of Conductive Fabric Over Foam and

the huge variety of profiles available makes theproduct suitable for a wide range of applications wherefull EMC screening is required between component

parts especially in high cycling and wiping applicationsand where low compression and excellent abrasionresistance are considerations. Typical applications include

• Cabinet doors.• Panel gaskets.• Grounding contacts.

• Card cage gaskets.• Connector and IO gaskets.

Availability

Proles are available in 2100mm lengths with someobtainable in continuous length. Depending on theprofile the product can be

• Cut to length.• Die cut to form fabricated gaskets.• Notched for 90 degree fabrication.

• Mitred.• Supplied with clip on and edge mounting or

with self-adhesive backing.

• Have re resistant properties to UL94VO.• Compression between 10% and 70%.


• Whilst a limited dust seal can be achieved, additionalenvironmental sealing, if needed, is required.

• Consideration must be given to compressionforces and corrosion compatibility.

• Consider the minimum land area on die cut parts,we would suggest that it is equal to the thickness

of the material.

Production CapabilityKemtron holds large stocks of Conductive Fabric

Over Foam profiles, which can be supplied to customersoff the shelf or die or kiss cut or fabricated to theirrequirements. Gasket fabrication is a routine feature

of our work enabling us to produce economic gasketsby maximising material usage, using a range of in-housecutting and stamping equipment, which is suitable for

prototype, short and medium production runs, up tocommercial quantities.

Product Overview

Beryllium copper (BeCu) spring finger and contact gaskets aremanufactured by punching or etching thin BeCu strip which is pressedand formed into the required final shape and then heat treated to giveit ‘memory’.

Due to their high conductivity, BeCu gaskets provide good EMI/RFI shielding together with lowclosure force properties and are available in a number of plated finishes and mounting styles.In certain closing applications the ‘wiping’ action enhances shielding performance.

The end product results in a low resistance contact finger with excellent anti-corrosion

properties that remains flexible within acceptable limits for many years.

BeCu fingers are suited for use in high cycling RFI/EMIand EMP applications where frequent access is requiredas their construction makes them resistant to fatigue and

only low compression forces are needed. They are suitedto high and low temperature applications and theirwiping action makes them ideal for use in:

• Cabinet doors.• Access panels.• Personnel doors in screened rooms and containers.

• Shielded rooms.

• Grounding contacts.

Availability

There are short lead times on most gaskets,which are available in a large range of standard profiles

in strips, generally 406mm (16”) long. Longer lengthsare available with some in continuous lengths.

Gaskets can be applied using adhesive tape, or canbe slot mounted, clipped on or soldered and in addition

to the standard finish can also be supplied in Tin,Nickel and Silver finishes.


This product does not provide an environmental seal.Over-compression can result in damaged fingers andloss of effectiveness.

Ensure galvanic compatibility with mounting surfaces.Fixing method must be appropriate to the applicationExposed gaskets are susceptible to damage, catching on

clothing etc.

Production Capability

BeCu gaskets are usually supplied in 406mm (16”)lengths, but can be cut to requirements and, dependingon the profile, are available in continuous longer lengths.

To ensure galvanic compatibility gaskets can be supplied

in a range of finishes including tin, nickel, zinc/clear

chromate, gold, silver and nickel.

Mounting styles include clip-on, stick-on, snap-on,

low profile and hook-ondium or large commercialproduction runs.

Handling ConsiderationsBeCu gaskets are fully RoHS compliant.

There are no special toxic hazards associated with thehandling of copper beryllium alloys. However cuts and

abrasions should be treated by normal first aid methodsand it is advised that after contact with copper-berylliumalloys the hands should be washed before food is eaten.

Care should also be taken, as with other metal alloys,to remove all metal particles from the wound whilstnormal hygiene standards should be observed.

Further information can be found in The Health

and Safety Executive (UK) – Guidance Note EH13‘Beryllium – health and safety precautions’.

Beryllium copper alloy 25 (CA172) is used in theseapplications for maximum spring properties ofstrengthand fatigue resistance.

Product Overview

Aluminium Honeycomb Air Ventilation Panels consist of an aluminiumhoneycomb foil held in a rigid extruded aluminium mounting frame.The foil, formed and laminated into a series of honeycomb cells that areglued and perforated or laser welded at the join, ensures a conductivepath at each join. Although the foil is conductive in all directions,to enhance EMI performance, two pieces of honeycomb polarised at90º to each other are recommended.

The frame can be supplied with an integral or separate EMI/RFI gasket,and can be treated with a variety of finishes to provide corrosion protectionor improve conductivity.

How do Honeycomb vents work:The principle is that of “Waveguide beyond cutoff. The honeycomb vent is series of tubes thatacts as a waveguide, guiding electromagnetic waves into or out of the enclosure, but as thetubes are long enough then it attenuates those waves. Typically the tube should be at least3 times as long as the diameter. Good practice is 4 times. Therefore a 3.18mm cell shouldbe 12.7mm long.Honeycomb material is used because it offers high shielding performance,light weight and good airflow.

A standard range of Honeycomb vents are available, drawings and part numbers are shown atthe end of this data sheet.










Applications

Ventilation panels are designed for use in electronicenclosures where good air flow is required for coolingand ventilation but where EMC compliance must be

ensured. Typical applications are:

• Electronic Enclosures.• Air Conditioning Units.

• Fan housings.• EMC Racks.• Communication shelters.

AvailabilityAn extensive range of aluminium extrusion mounting

frames are available from stock offering a choice of

mounting methods and sizes.Available as custom sizes with no additional cost.

Frames can be supplied with fixing holes or captive

threaded inserts to aid mounting.

Honeycomb can be supplied in a number ofconfigurations to suit different EMI/RFI Shielding

performance requirements. Such as straight through,polarized and a choice of cell size.

Standard perforated honeycomb is available with 30˚,45˚, 60˚ and 90˚ angles from stock and Laser welded

aluminium honeycomb is also available to special order.

For vulnerable situations weld mesh or expandedaluminium kick plates can be fitted.

Removable dust filters and integral insect screens canalso be provided.

A range of low cost standard fan vents are available tomeet commercial applications where lower performance

is acceptable, consisting of one layer of aluminiumhoneycomb held in a plastic frame.


Any environmental conditions such as moisture anddust control including:

• Air Flow requirement.• External louvers for rain protection.

• Drain holes.• Any additional gasketing.

Constructional requirements and finishes including:• Angled honeycomb for rain protection or directional

air flow.

• Rigidity of vent frame and enclosure so as toprevent bowing of either surface when compressingthe gasket.

• Fixing requirements e.g. holes or threaded insertsensuring appropriate position and size of hole-centres.(Holes in the corners of the frame should be avoided.)

• If specifying captive inserts in both sides of the frameoff-set the positions by 10mm minimum.

• Round vents tend to be an expensive option due

to the complexity of manufacturing method.• Fully welded corners.• Type of gasket required.

• Frame style.• Honeycomb conguration.• Corrosion, electrical conductivity etc,

(see Finishes section)• Weld mesh or expanded aluminium kick plates

• Removable dust lters and integral insect screenscan be provided

Production CapabilitiesKemtron manufacture its range of EMC vent panels

using the latest technology and, with the exception ofpainting and plating, all processes are kept in house,giving us flexibility and total control over quality.

Kemtron has invested heavily in this area making us themarket leaders for price, delivery, quality and availability

Fully programmable CNC machines for the notching &

cutting of the frame extrusions and drilling of exact andrepeatable holes combined with the latest TIG welding

equipment allows Kemtron to offer a fast delivery of itscompetitive range of aluminium vent panels producedto customer designs. This advanced technology alsoeliminates the need for additional tooling and set-up

charges. Kemtron holds a large range of aluminiumextrusions and aluminium honeycomb in stock.

In addition to vent panels, Kemtron manufactures ahuge range of EMI shielding products, including

conductive Elastomers, oriented wire, knitted wire mesh,connector gaskets.

Vent panels made with styles 1701, 1703, 1705, 1706

& 1707 are supplied with 3 corners notched and the4th joined corner welded and have an external cornerradii of 3mm.










Honeycomb specification and availability:

Kemtron uses 5052 grade aluminium foil which is alightweight material offering superior strength andcorrosion resistance over commercial grade aluminium

foils. It meets all the requirements of MIL-C-7438.

Standard straight cell sizes & thicknesses held in stock

• 3.2mm (0.125”) cell x 12.70mm (0. 50”) thick

• 3.2mm (0.125”) cell x 6.35mm (0.25”) thick

• 1.6mm (0.0625”) cell x 6.35mm (0.25”) thick

• 3.2mm (0.125”) cell x 3.2mm (0.125”) thick

Standard slant cell sizes, angles & thicknesses held in stock

• 3.2mm (0.125”) cell x 6.35mm (0.25”) thick x 30˚



Kemtron’s standard honeycomb vent uses 2 layers of1

/ 8” cell X ¼” thick laid at 90°, this is known as cross cell.Cross cell honeycomb improves shielding performance byeliminating any polarizing effects.










Frame styles available

Frame styles 1701,1702,1703,1704 and 1707 willaccommodate 2 layers of 3.2 x 6.35mm thickhoneycomb, one layer of 3.2mm cell x 6.35mm thick

and one layer of 3.2mm x 6.35mm thick angledhoneycomb or one layer 12.7mm thick honeycomb

Frame styles 1705 and 1706 will accommodate 1 layer

of 3.2 or 1.6mm cell x 6.35mm thick honeycomb.Also possible to accommodate 2 layers of 3.2mmcell x 3.2mm thick honeycomb

Frame style 1709 main use is for dust filter panels thatcan be fitted over EMC vent panels, but canaccommodate one layer of 3.2 or 1.6mm cell x 6.35mm

thick honeycomb, however this is not recommended.

Frame style 1708 is a dividing/support bar for large vents.

Vents are normally supplied with three notched and onewelded corner to achieve the best trade off between

cost and performance. This combined with an EMCgasket is normally sufficient for all but the mostdemanding EMC specifications. In the event that the

best possible attenuation is required all corners can besupplied fully welded. Please note that styles 1702 &1704 are always supplied fully welded due to the nature

of their construction.

Finishes

Vent panels can be supplied with a range offinishes including:

• Painted.• Tin or nickel plating.

• Kempass (RoHS ) Aluminium Passivation process.• Trivalent chromium (RoHS compliant)

or Hexavalent chromium.

Kemtron’s standard finish (Kempass) for aluminiumvent panels fully meets the RoHS directive and replaces

Alocrom1200 which is a hexavalient chromium process.Kemtron’s in-house process applies a permanganatepassivation which is a chromate free, inorganic and

non toxic coating. The process produces a dense,

uniform coating consisting of aluminium and reducedmanganese oxides giving a light yellow colour to the

surface. The surface finish is conductive with a lowcontact resistance equalling Alocrom 1200. It also meetsall requirements of MIL-C-5541E for corrosion and

electrical conductivity. We are also able to offer acomprehensive range of painted finishes to complementour standard Kempass finish. Using industry leading wet

paint solutions from Trimite, we offer full painting andpreparation to DEF STAN specifications including mattand gloss finishes.

In addition we can also offer Infra Red Reflecting (IRR)

matt finishes complying with DEF STAN 00-23, 80-166

and STANAG 2338.For less critical / commercial applications requiring a

protected finish we recommend polyester powdercoating. This is tough material that offers excellentresistance to fresh and saltwater, petrol, linseed and

penetrating oils, along with limited resistance to variousacids. We are happy to advise on specific examplesif required. As the epoxy process is an electrostatic

method, it offers excellent penetration of thehoneycomb cells, further aiding resistance to corrosion.With both processes, we are able to offer a full range

of colours to RAL/BS charts.









Gaskets for vents

• Knitted wire mesh = Frames with a gasket groove.• Orientated wire in silicone.

• Knitted Monel wire mesh with a Neoprene spongecarrier 2.4mm thick.• Beryllium Copper nger stock.

Other gasket types are available if required

Beryllium copper gasket

Oriented wires in silicone gasket

Knitted wire mesh gasket

Kmitted wire mesh with neoprene gasket

Kick PlatesAluminium honeycomb is fragile so for high traffic areasor where honeycomb damage could easily occur kick

plates can be fitted. Two types are stocked as standard,however custom designs to customers specificrequirements (i.e louvred openings) are available.

Expanded aluminium provides maximum protection but reduces

air flow

Woven stainless steel provides lower protection but higher air

flow.











Fan Vents

A range of low cost plastic EMC vents for use with80mm, 92mm & 120mm fans. They provide EMCshielding where applications demand a low cost solution,

whilst still providing an adequate shielding performance.A Hi-impact ABS UL94V-0 fire retardant moulding isfitted with one layer of 3.2mm cell x 6.35mm thick

honeycomb and a nickel/copper fabric gasket to groundthe honeycomb to the metalwork. The vents have 4countersunk holes to suit standard fan mountings.

Measured shielding performance in accordancewith Mil Std 285 (80mm size tested)

Optional Removable Dust Filters and Insect Screen

Dust Filter

This consists of a aluminium frame 1701, 1705, 1706,1707 & 1709 which holds a polyester polyurethane dustfilter. This is held in place on one side by a stainless steelweld mesh. This frame then mounts on to one side

of the honeycomb vent panel by captive screws.Easily removed for cleaning with a mild detergentand rinsed with water. A range of different filter

options are available.

Aluminium honeycomb vent panels fitted with removabledust filters usually require assisted air flow.

Standard filter foam is stocked in two thicknesses to suit

the above frame styles.

30, 45 and 60 pores per inch, others are available tomeet specific requirements.

Insect Screen

This is a woven aluminium cloth inserted on one face orbetween the honeycomb and provides protection from

the ingress of insects. Wire dia 0.28mm open area 66%.

charges. Kemtron holds a large range of aluminiumextrusions. In addition to vent panels, Kemtron

manufactures a huge range of EMI shielding products,including gaskets to compliment the vent panels.

Finishes


• Painted (frame only for dust panels).• Electro less plated Tin or Nickel.



Kemtron’s standard finish (Kempass) for aluminiumvent panels fully meets the RoHS directive and replacesAlocrom1200, which is a hexavalent chromium process.

Kemtron’s in-house process applies a permanganatepassivation which is a chromate free, inorganic and nontoxic coating. The process produces a dense, uniform

coating consisting of aluminium and reduced manganeseoxides giving a light yellow colour to the surface. Thesurface finish is conductive with a low contact resistance

equalling Alocrom 1200. It also meets all requirements ofMIL-C-5541E for corrosion and electrical conductivity.

We are also able to offer a comprehensive range ofpainted finishes to complement our standard Kempass

finish. Using industry leading wet paint solutions fromTrimite, we offer full painting and preparation to DEFSTAN specifications including matt and gloss finishes.

In addition we can also offer Infra Red Reecting (IRR)matt finishes complying with DEF STAN 00-23, 80-166and STANAG 2338.

For less critical / commercial applications requiring aprotected finish we recommend polyester powdercoating. This is tough material that offers excellent

resistance to fresh and saltwater, petrol, linseed andpenetrating oils, along with limited resistance to variousacids. We are happy to advise on specific examples if

required. With both processes, we are able to offer afull range of colours to RAL/BS charts.

Product Overview

Shielded windows provide a high performance EMI shield whilemaintaining optimum optical transparency.

Screening or shielding of optical windows is achieved by using either:• A very ne woven wire mesh trapped between or embedded in a clear optical

substrate such as acrylic, polycarbonate or glass, or• A transparent vapour deposited conductive coating such as Indium Tin Oxide

or Gold applied to the surface of the clear optical substrate.

Termination of the window to the enclosure is achieved with a continuous low resistance

conductive edge around the window, either a conductive buss bar and conductive gasket,or extended wire mesh (see window mounting)


ApplicationEMI shielded windows provide an EMI screen as

part of a shielded enclosure which will provideprotection against radiated emissions and susceptibility.Shielded windows provide good transparency for

viewing display devices such as LED, LCD, vacuumfluorescent, plasma etc and they can also form thefront panel of an enclosure to provide impact protection,

contrast enhancement of displays, display colourmatching, anti reflection and an anti glare surfaces.Large windows can provide transparent EMI shielding

for architectural use such as computer rooms, shieldedrooms, MRI rooms and secure communication cabins.

AvailabilityEMI shielded windows are made to customerspecication. Sizes can range from 1cm² up to

1x2 metres for architectural use. Windows can besilk screened or printed with logos, information etc.Termination can be by mechanical clamping using

a conductive gasket or by bonding into the enclosurewith a conductive adhesive.

Optical Substrates

Acrylic is a versatile substrate available in a range ofcolours to match display outputs to improve contrast

enhancement including clear, which exhibits 92% lighttransmission, through to infra-red transmitting opaquematerials. Acrylic is easily machined and formed making

it suitable for front panels needing cut outs, holes,steps etc. Multiple layers can be fully laminated withne wire meshes together with different colour

combinations and the inclusion of circular polarizers.Acrylic has a UL94HB ammability rating and hard antiscratch, chemical resistant coatings can be applied to

the surface as an optical flat or as anti-glare.Polycarbonate has very high impact resistance, morethan 16 times that of Acrylic and 200 times more thanglass making it most suitable for rugged applications.

Whilst its light transmission is not as good as othersubstrates at 85%, it has the advantage of havingUL94VO ammability rating over 2.4mm thickness.

Hard anti scratch, chemical resistant coatings canbe applied to the surface as an optical flat or asanti-glare. Fine wire meshes can be fully laminated

between two layers.

Glass has a very durable surface and will withstandhigh temperatures making it suitable for the application

of vapour coatings such as ITO (indium tin oxide) forEMI shielding and/or anti reflection coatings that willreduce rst surface reections to less than 0.5%.Glass can be fully laminated with ne wire meshes

and circular polarizers when required.

ADC (Allyl Diglycol Carbonate), trade name CR39,has a very hard surface hence its use as spectacle lenses.

ADC is normally cast and has good impact resistanceand is highly formable but is easily broken if scratchedor notched. ADC meets UL94HB ammability rating

but is the most expensive substrate.

Shielding Media

Fine Wire Meshes provide the highest level ofshielding while maintaining excellent optical properties.

Wires used as the EMI shield are stainless steel orcopper. The stainless steel mesh ranges from 50 wiresper inch up to 250, copper mesh 70, 100 and 145.

Wire diameters are 0.025mm or 0.056mm for stainless,0.056mm for copper. The greater wire density givesbetter shielding performance but light transmission

and optical clarity is degraded. The optimum wirecount to achieve good shielding and opticalcharacteristics is around 80-100 wires per inch.

The wire is plated and blackened to fuse the wirecrossovers ensuring consistent EMC performance andthe blackening reduces specular reflection from themesh, enhancing the optics. Wire meshes can cause

moiré fringing on some displays. To eliminate this thewire is orientated in the substrate at an angle to bedetermined during the window design, this may from

11 to 45 degrees dependant on the display.

Transparent Vapour Deposited Conductive CoatingsITO (indium tin oxide) and Gold can be applied to thesubstrates but do not provide as effective shielding as

the wire meshes. Their advantage is that optical clarityis maintained and there is no degradation in resolution

or fringing that can be caused by ne wire meshes.The coating can be applied in various thicknesses to

achieve a resistance of 5, 10 or 25 ohms/square.

Product Overview

Kemtron distribute a large range of ferrites for EMI suppression. Ourwarehouse facility has a large range of cable and surface mount productswhich are generally available for same day despatch. Non stocked parts canalso be obtained in a few working days.

Kemtron distributes from world leading producers of ferrite and related materials used in theelectronics, copier, telecomms, military and automotive industries. Nickel zinc ferrite parts areused extensively in the suppression of electromagnetic interference commonly known as EMIFerrite, materials exhibit magnetic properties which are dependent on the frequency at which

they are excited. In electronic applications the relation of the magnetic loss to frequency isutilized to attenuate interference frequencies where the material’s losses are high, yet passthe lower bands where data is carried.

The Kemtron range of EMI ferrite is split into two main areas:

• Cable ferrites, comprising solid and split core versions for use on round and ribbon type cables. Broadband & High Frequency versions are now available for round andcylindrical cores.

• Board Mount Products, comprising chip ferrites, common mode chokes, multi-turn devices etc, many available in both surface mount and through hole board versions.

The ranges are extensive and continually being updated, please visit our web site to view therange or contact our sales office to discuss your requirements.

Environmental SealingFlat Gaskets

Product Overview

Kemtron has the capability to produce many designs and styles of flatgaskets. We have a versatile process of manufacture, which is ideally suitedfor development and pre-production through to full production volumes.Modern tooling, enable complex shapes to be produced whilst maintainingtight, repeatable tolerances. Single or multipart tool configurations allowfor efficient, economical production techniques.

Flat gaskets are produced from sheet while larger gaskets can be cut from fabricatedpicture frames.

This option has the advantage of saving material and allows larger gaskets to be producedeconomically. This is facilitated by our in-house tool making and silicone moulding facilities.Fabricated frames use either extruded or moulded flat section that is joined by vulcanizingthe polymer.

This process has allowed Kemtron to produce gaskets up to 2 meters long, with the samemechanical integrity as is found in a single part gasket cut from sheet. This method ofmanufacture often offers cost savings over cutting from sheet with subsequent loss of wastematerial. During this process compression stops or collars can also be incorporated. This leadsto reduced hardware costs and negates the need for fixings to be torqued to prevent overcompression and damage to the gasket.

Our experience in laminating allows us to apply self-adhesive backing tape to even the mostdifficult materials such as silicone, regardless of quantities. We use a range of high performancetapes suitable for all conditions.

Kemtron has in house slitting capability, which allows us to convert sheet or log materials intostrip or coils. This flexible technique with short lead times allows materials to be supplied toexact customer requirements with low minimum order quantities.











Availability

• Continuous lengths up to 5 mtrs long for slit coils.• Fabricated gaskets to customer’s drawings.• Can be tted with compression limit stops or collars.• Easily assembled using the self-adhesive backing

option. (Self-adhesive backing is an assembly aid only).

• A broad range of sizes available.• A large range of materials to suit many

climatic conditions.

• Large fabricated gaskets can be producedeconomically.

• UL ame retardant approved materials

are also available.


• It is important that this material is not over-compressed. If the design of the equipment

does not allow for any mechanical method of

preventing over-compression, the gasket should be fitted with built-in compression limiters, either metal

stops fitted to the gasket, or metal collars fitted into

each fixing hole.• When specifying die cut gaskets minimum material

width should not be less than 2mm or at least the

material thickness in any part of the gasket. If thiscannot be achieved around fixing holes consider usinga slot. Particular attention is required if specifying

compression collars in holes.

• Particular consideration must be given to compressionforces, hole centres, size and number of fixings and

rigidity of mating flanges.

Environmental SealingForm-in-Place

Product Overview

Kemtron Form-in-Place (FIP) Elastomer compounds are directly dispensedonto component hardware or enclosure via a pressurised fluid dispensingsystem on a numerically controlled XYZ table to form a gasket for dust andmoisture sealing. The dispensing machine deposits the gasket by followinga pre-determined CNC path to provide accuracy and repeatability.


The process advantages are:

• Component provides an integratedenvironmental gasket.

• Assembly time is reduced as gasket is included

on component.• Rapid prototyping.• Low setup costs.

• Smaller gasket land required.• No material waste.• Can be applied to metal and plastic components.

ApplicationsSuited to applications where small, intricate gasketproles are required, such as on multi-compartment

labyrinth housings with minimum gasket land areawhere traditional larger types of gasket are not suitable.

This process also negates the assembly costs associated

with traditional gaskets as the Form-in-Place gasketbecomes an integral part of the housing or enclosure.

The process is suitable for depositing on both metal and

metallised plastic components/housing.

Availability

Kemtron can dispense FIP gaskets directly onto the

customer’s free issue hardware or can procure thecomponent hardware thereby reducing the customer’ssupply base.

Design Considerations• The gasket height can be specied between 0.4mm to

2.0mm, gasket width will typically be 1.5x the gasketheight.

• Recommended gasket compression is between 20%

and 30%. Over-compression can damage the gasketand as compression stops cannot be incorporatedinto the gasket they should be designed into the

component hardware.• Gasket path for the deposition can be determined from

a sample part, drawings or CAD les.

Production CapabilityTo meet the varying demands of customer requirementsKemtron has developed its own CNC Form-in-Place

dispenser. FIP gasketing work has become a regularfeature of our production work and we are able toprovide a reliable, accurate and quick response to even

high volume orders.

Kemtron has a large range of compounds suitable formany climatic conditions. Wide temperature range,

chemical resistance & fire retardant grades.

Environmental SealingSilicone ‘O’ Rings

Product Overview

Kemtron’s experience in the manufacture of Silicone ‘O’ rings is extensive,our preferred method of production is extruded and vulcanised. We have alarge selection of vulcanising tools to suit our standard extrusions.

The jointing process uses the same polymer compound ensuring gasketintegrity is maintained across the joints.

Moulded versions are available if specifically requested.

Both silicone & fluorosilicone are available for the manufacture of ‘O’ ringsin solid cord, tube and sponge. Please note that fluorosilicone is notavailable in sponge.


Advantages Of Vulcanised ‘O’ Rings• Cost effective.• No tooling costs.• Reduced lead times.

• Better surface nish (zero ash).• Allows hollow sections and sponge to be used for

lower compression force.

• Custom sizes are easily produced with restriction on

developed length.• Tight tolerances on developed length and cross

section.• Vulcanised ‘O’ rings with a ID as small as 10mm

depending on cord diameter.

Design Considerations• When selecting a prole it is important to give

attention to the mechanical design of your product.Round and D section seals should ideally be mountedin a suitably sized groove.

• If the gasket is to t in a groove. It is important thatthe gasket size chosen does not overll the channel,when using solid sections you should ensure that

the groove cross sectional area is a minimum of 5%greater than the proposed gasket cross section.• Attention must also be paid to the closing force

required to compress the gasket to the workingheight required.

The above cross sectional area groove sizes allow for thefree movement of the gasket when being compressed.This method of calculation ensures that the volume of

the gasket does not exceed that of the groove whenfully compressed, resulting in groove overfill. This alsominimises the amount of compression force required to

achieve a good seal.

It is important to note that when designing in a gasket,that the principles of O ring design for pressure sealing

do not apply. The groove depth dimension is the mostimportant, as it is this that limits the gasket compression.The groove width has no maximum dimension and is

only there for gasket location purposes. Tighter groovedimensions using volume calculations may be employedto enhance environmental sealing. However this willincrease the compression forces required.

The above calculations are based on reducing the depthof the groove by a given compression % and increasingthe width by the same amount less 5% eg. 20%

reduction in depth 15% increase in width.

When choosing a tube section as a gasket it isrecommended that consideration be given to the lower

compression forces, making sure that there is enoughresilience in the gasket to ensure a good seal. In thesecases it is sometimes better to use the volume groove

size calculation, with the groove side walls offeringsupport for the tube. Because there are so manyvariables with tube cross sections it is difficult to give

precise information on this subject. Kemtron are able tosupply samples for evaluation purposes.








Internal Bend Radius

The minimum internal bend radius of a solid cord gasket is 1.5 x cross

section of cord.

The minimum internal bend radius of a tube gasket where the id of the

tube is no greater than 30% of the cross section is 2.5 x cross section of

tube.
