LCP- Lyotropic or Thermotropic


Lyotropic►Very high melt point (~ 700°C)

> Decomposition temperature►Processed only in solution►High intermolecular forces►DuPont Kevlar®

Thermotropic►Melting point 200°C to 400°C►Melt processable►Weaker intermolecular forces►Vectra® / Zenite® LCP

General Attributes of Thermotropic LCP’s


Melt

Stress

Solid State

Even in the melt, LCPs are aligned in small regions… like uncooked spaghetti. The polymer chains further align and “slip” over each other as they flow into the runner and part. Since they are already oriented when they stop flowing, there is very little heat of fusion (freezing) so the resins sets up very fast!

Liquid CrystalPolymer Resins

ConventionalSemi-Crystalline Resins

Comparison of Amorphous Polymers vs. Semi-Crystalline Polymers. Where do LCP’s fit?

Amorphous Polymers Semi-Crystalline Polymers Liquid Crystal Polymers

No sharp melting point / soften gradually

Relatively sharp melting point Melt over a range of temperature; low heat of fusion which is about 5-10% of Semi-Crystalline resins

Random chain orientation in both solid and melt phase

Ordered arrangement of molecular chains and regular recurrence of crystalline structure only in solid phase

High chain continuity; extremely ordered molecular structure in both melt phase and solid phase

Do not flow as easily as semi-crystalline polymers

Flow easily above melting point Flow extremely well under shear above melting point yet tend not to flash due to fast freeze rate. Will flow even below “melt point” due to partial chain melting

Fiber glass and/or mineral reinforcement only slightly improves HDT

Reinforcement increases HDT considerably

Reinforcement reduces anisotropy and increases HDT

Can give transparent parts Part is usually opaque due to the crystal structure of semi-crystalline resin

Part is always opaque due to the crystal structure of LCP


Why do Customers use LCP’s?

►Very fast cycle times►High short-term temperature resistance►High long-term temperature resistance ‒ RTI up to 240°C

►Dimensional stability (Essentially no moisture absorption)►Very high flow without propensity to flash‒ Sections down to 0.15 mm

►Low Coefficient of Thermal Expansion (Flow direction esp.)►Inherently flame resistant…no added flame retardants ‒ Halogen and phosphorous free

►Extremely low out-gassing

Change in Shrinkage


Shrinkage during SMT is primarily cross flow which tends to increase and raise the total stress in the part.

to increased stress and warpage

Warpage

Empirical Data from Several Resin Families


Calculated Warpage

In General, Warpage tends to be non-linear with shrinkage differential and the stiffer the sample, the less warpage for the same differential shrinkage, eg., 3mm disks tend to warp less than 0.8mm disks molded from the same resin.

Warpage – 1.6mm x 100mm
