RTP COMPANY TECHNOLOGIES

EMI SHIELDINGOur Electromagnetic Interference (EMI) Shielding Compounds offer reliability and value in a wide range of applications where electromagnetic compatibility is required. Shielding provides protection for sensitive components from incoming EMI and/or prevents excessive emissions of EMI to other susceptible equipment.

Typically, EMI shielding compounds utilize stainless steel fiber or nickel-coated carbon fiber in a thermoplastic matrix to provide the necessary shielding. These compounds can also incorporate flame retardant additives, wear additives, reinforcements, and colorants in a single custom material solution to meet the requirements of your application. Furthermore, these unique compounds can provide you with tremendous flexibility and significant benefits over metals, metallized coatings, and other EMI technologies. Figure 1 compares the properties of four such groups of EMI Shielding Compounds, which can be fine tuned to meet the specific requirements of your application.

Figure 1: Property Comparison: EMI Shielding Compounds Shielding Effectiveness (SE) @ 2mm Thickness

Housings for radar boxes, GPS module enclosures, sensors, and cameras require EMI shielding to prevent signals from being mixed or interrupted. EMI Compounds can provide this protection and help to ensure the proper function of these sensitive components.

FLAME RETARDANT COMPOUNDS

Although flammability is not often a concern with conventional gas powered vehicles, electrical and autonomous vehicles do require a fresh approach to passenger safety. Most thermoplastics utilized in the automotive industry today are inherently flammable, and therefore require an additive package to meet industry flame standards such as UL94 V-0; in addition, they must function well in the end application.

RTP Company offers materials with differing physical properties that can address specific needs and issues associated with electric and autonomous vehicles, including exposure to various loads/abuse, extreme temperatures, and chemical or UV rays (Figure 2). We can also provide alternate materials that target different specifications or custom materials to address specific flammability or safety concerns.

STRUCTURAL COMPOUNDS

Our Structural Compounds provide solutions in applications requiring excellent mechanical and/or thermal performance. Vehicle parts and components made from these structural compounds have excellent impact resistance, aesthetically pleasing surfaces, and lower density for lighter weight. Additive technologies that bring the highest value include:

• Short Glass Fiber (SGF) Compounds – chopped glass fiber provides strength and stiffness to our SGF compounds, which in turn provides good, general purpose reinforcement properties.

• Very Long Fiber (VLF) Compounds – in addition to an improvement in strength and stiffness versus SGF Compounds, VLF Compounds provide improved impact strength and are commonly used for metal replacement.

The “frunk”, or storage space under the front hood of an electric or autonomous vehicle, can be made from VLF Compounds for excellent durability and impact.

For applications that require aesthetics, UV protection, and weatherability, we formulate ASA Alloys that provide high gloss, colorability, and UV performance. In addition, these alloys provide higher chemical

resistance and thermal stability versus standard ABS, making them an excellent choice for thermoplastic housings on charging stations.

UV Resistance

• Carbon Fiber (CF) Compounds – our CF Compounds provide tremendous stiffness without adding significant weight to a vehicle. These high end materials, which are commonly used in aerospace, are finding broader use for lightweighting in electric and autonomous vehicles.

Figure 3 depicts commonly used materials available from RTP Company that provide structure, mechanical performance, and lighter weight for vehicle applications.

HIGH TEMPERATURE THERMOPLASTICS

Our high temperature compounds are formulated to withstand high heat environments, making them an excellent choice for electric motors, battery systems, and mating connectors. Made from resins that inherently offer better mechanical performance and both wear and chemical resistance, we can also tailor these products to meet specific application requirements. By selecting from a broad range of polymer and additive combinations, we can provide the precise color, mechanical function, wear resistance, dimensional stability, conductivity, and regulatory requirements of your application in a single, cost-optimized solution.

COLOR COMPOUNDS

Color can be used in many ways, including to draw attention, communicate instructions, enhance safety features, build brand awareness, create special effects, and more. Choose from our standard color palette or request a custom color match! Our color compounds are available in Precolor, Masterbatch, or Cube Blend, and can be enhanced with functional additives such as UV protection packages to prevent fade and deterioration for applications such as exterior housings or charging stations.

In fact, our experts can create a custom formulation in the color of your choice, and provide guidance on matching the color of components made from other materials – ideal for creating a harmonious environment in the vehicle interior. For example, we can formulate special colorants that reflect near-infrared energy, which help reduce the heat buildup in the interior of the car. These solar-reflecting colorants can meet the desired interior hues while providing material performance benefits and increased consumer comfort when outdoor temperatures are high.

High Temperature Mineral Filled Compounds provide improvements in dimensional

stability and stiffness in high temperature environments over

unmodified resin.

THERMOPLASTIC ELASTOMERS (TPEs)

From off-the-shelf resins to complex custom compounds, our TPEs provide unique benefits for electric and autonomous vehicles, including improved ergonomics, noise reduction, and superior sealing ability. Available in durometers ranging from 10 shore A to 65 shore D, they are commonly used in automotive parts such as seals, gaskets, air deflectors, handles, and grips. Our Nylabond™ and Polabond® materials are bondable to various substrates including Nylon, ABS, PC, PC/ABS and other engineering resins, while our high temperature TPV technology bonds well to nylon substrates for applications used in extreme environments.

WEAR COMPOUNDS

Our Wear and Friction Resistant compounds solve a number of issues, including noise, abrasion, friction, and scratching/marring. Noise is particularly important in the case of electric and autonomous vehicles, since the expectation is a quiet cabin. Molded parts made from our wear and friction resistant compounds can be internally lubricated and provide noise reduction between mated or sliding parts. In addition, they provide protection from scratching and marring of surfaces, as well as excellent oxidation and corrosion resistance for handles, latches, gears, bushings, and more.

ADDITIONAL MATERIALS

Several divisions of RTP Company provide special materials designed with the automotive market in mind. For applications like touch screens, we offer optical cast sheet for improved optical quality, chemical and abrasion resistance, thermal stability, and light weight.

In addition, we can provide reclaimed fiber materials, ideal for cargo/frunk liners and mats. Only RTP Company offers the widest selection of material solutions for every aspect of electric and autonomous vehicles.

Our NylabondTM nylon bondable TPVs can be overmolded to a rigid substrate to improve part integrity, eliminate the need for adhesives, and enhance grip performance for parts like gear knobs.
