This materials is…

an excellent machining amorphous  thermoplastic which possesses a combination of useful characteristics, including high strength at elevated temperatures, high modulus, and broad chemical resistance.  Material displays property retention and resistance to environmental stress cracking when exposed to a wide variety of chemicals. Material is extremely rigid, dimensionally stable and able to withstand continuous operating temperatures of 340ºF.

  • Excellent Machining Properties
  • Extremely Low NBS Smoke Evolution
  • Inherent Flame Resistance UL 94 5VA at .075″
  • 340ºF Continuous Use Temperature
  • Chemically Resistant to Chlorine and Caustic/Acidic Cleaning Agents
  • Offers excellent strength, rigidity and machinability

Great for applications that require improved stiffness, glass fiber filled grades with filler levels of 10% – 40% are available. Because it offers superior resistance to autoclave sanitizing and is FDA/USDA and USP class VI compliant, PEI is frequently specified for reusable machined components used in the medical and pharmaceutical industries. First introduced by General Electric Plastics in 1982. Other material trade names for PEI: Unitem®, Tempalux, Sustatec .
