Overview
DuPont™ Vespel ® polyimide is an extremely high temperature, creep resistant material that is often used in high heat environments where thermoplastic materials would lose their mechanical properties.
Vespel ® is available in a variety of formulations including an unfilled grade and several bearing and wear grades.
Vespel ® SP-1
Unfilled Vespel ® SP-1 has outstanding sealing properties when it interfaces with metal mating parts. These properties make Vespel ® ideal for use in un-lubricated, high temperature, and high pressure or high vacuum valve seat and gasket applications.
Bearing Grades of Vespel ®
Vespel ® SP-21, SP-22, SP-211, and SP-3
Bearing grades of Vespel ® will operate successfully without lubrication in high load, high speed, and/or high temperature environments where thermoplastic bearings and many metal bearing materials will quickly fail.
Introducing...Vespel ® SCP-5000
Technology advances have led to the development of DuPont™ Vespel® SCP-5000, an unfilled polyimide copolymer developed for demanding applications that require toughness, thermal and dimensional stability, chemical resistance and stable dielectric performance across a broad temperature range.
This product is a good candidate for applications such as CMP retaining rings, test sockets, substrate lift pins or any other application that requires high temperature and/or high wear resistance with low outgassing.
Compared to Vespel ® SP-1, SCP-5000 offers:
- Higher modulus, strength, and surface hardness
- Improved dimensional stability
