| An amorphous thermoplastic polyetherimide, stock shapes from ULTEM® resin possess a combination of useful characteristics, including high strength at elevated temperatures, high modulus, and broad chemical resistance. Tempalux stock shapes are inherently flame resistant with low smoke emission. Tempalux stock shapes display property retention and resistance to environmental stress cracking when exposed to a wide variety of chemicals. The standard color of Tempalux stock shapes is light amber. Glass filled grades appear tan or greenish in color. Tempalux rod, slab, and tubular bar are air annealed for stress relief. Applications Include: Burn-in test sockets Connectors Automotive components Valves, electrical fittings Advantages of Tempalux: Inherent flame resistance Extremely low NBS smoke evolution Superior limiting oxygen index Exceptional tensile and flexural strength Broad chemical resistance UV stable FDA compliant&& |
