Request Information
ULTEM® 1000 PEI/Polyetherimide is a high performance amorphous thermoplastic material. Stock shapes made from ULTEM® PEI resins possess a combination of useful characteristics, including high strength at elevated temperatures, high modulus and broad chemical resistance. ULTEM® PEI stock shapes are inherently flame resistant with low smoke emission. ULTEM® PEI stock shapes display property retention and resistance to environmental stress cracking when exposed to a wide variety of chemicals. The standard color of ULTEM® PEI is light amber. Glass filled grades appear tan or greenish in color.
  • ASTM D5205 PEI0113.
  • UL94 V-0.
  • FDA Compliant.
