PI (Vespel®)

The raw material for a new age.

Parts made of VESPEL® Polyimid prove themselves to be extremely stable in their dimensions. Heat resistance which many other plastics do not achieve. Even placed shortly in a temperature reaching 482°C, VESPEL® parts do not melt or soften up.

  • very good wearing properties
  • electrically insulating
  • extreme heat resistance 
  • good resistance against acids 
  • high long-term strength as well as an excellent resistance to shocks 
  • no corrosion
  • low gas exhalation
  • excellent resistance to radiation
  • easy machining without special equipment or methods
  • good adaption to forms but does not warp
