For more than 35 years, our engineers have been providing precise thermoplastic solutions for the automotive industry, ranging from high volume engineered materials to high tech specialty compounds. We support the industry’s commitment to sustainability by formulating thermoplastic compounds that make good sense for electric and autonomous vehicles, as well as their charging stations.

Because electric and autonomous vehicles have different requirements than internal combustion engine vehicles, the types of materials used can be very different than those that have been used historically… so we have a variety of options! Our materials are specially formulated to enhance and improve parts that are used in electric vehicles, autonomous vehicles, and charging stations, with benefits such as:

  • strength
  • performance
  • lighter weight
  • flame retardancy
  • reduced VOCs
  • better efficiency
  • cost reduction

EMI Shielding

Our 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.

Electric Vehicle EMI Shielding
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.

Structural Compounds

Our Structural Compounds provide solutions in applications requiring excellent mechanical and/or thermal performance.

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

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