Tempalux® Family

Tempalux®

Tempalux® Polyetherimide (PEI) is made from resin that is suitable for use in certain food contact applications, contact your local Westlake Plastics representative for specific regulatory declarations. Tempalux is an amorphous material that offers a combination of useful characteristics, including high dielectric strength, high strength at elevated temperatures (up to 180°C for extended periods of time), high modulus, and broad chemical resistance. Tempalux® is inherently flame resistant with low smoke emission. The material has good resistance to environmental stress cracking when exposed to a wide variety of chemicals.
