What is Ultem?

Ultem (also called PEI) is a special plastic that can:

  • Stay strong in very hot places (up to 340°F)
  • Not break down when touching harsh chemicals
  • Not conduct electricity (works as an insulator)
  • Meet FDA rules for medical use
  • Be flame-retardant (doesn’t catch fire easily)

These amazing features make Ultem perfect for aerospace parts, medical tools, and electronics where normal plastic would melt or break.
