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
