Westlake Plastics Tempalux® 5000 Polyetherimide  (discontinued **)
Categories: Polymer; Thermoplastic; Polyetherimide (PEI)

Material Notes: An amorphous thermoplastic polyetherimide, stock shapes from ULTEM® resin possess a combination of useful characteristics, including high heat resistance, 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.

Applications Include:

  • Medical instrument trays
  • Burn-in test sockets
  • Aircraft / Aerospace interiors
  • Connectors
  • Automotive components
  • Valves, electrical fittings
  • Food service (ovenable)
  • Flex Circuits

Advantages of Tempalux 5000:

  • Inherent flame resistance
  • Extremely low NBS smoke evolution
  • Superior limiting oxygen index
  • Exceptional flexural and tensile strength
  • Broad chemical resistance
  • UV stable - inherently
  • FDA Compliant
