Tempalux® Family
Tempalux®
Tempalux® Polyetherimide (PEI) 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.
