Extremely high temperature creep resistant plastic with excellent friction and wear characteristics
DuPont™ Vespel® Polyimide is an extremely high temperature, creep resistant plastic material that is often used in high heat environments where thermoplastic materials lose their mechanical properties. Vespel®, a lightweight alternative to metal, is available in a variety of formulations including unfilled grades and several low friction and wear grades.
The Vespel® SP Family of products are highly durable polyimides used in demanding applications where exceptional thermal resistance, low wear and/or low friction, strength and impact resistance are desired.
DUPONT™ VESPEL® IS WIDELY USED FOR:
- Semiconductor and material handling machinery
- Chip test sockets
- Wafer clamping rings
- Valve seats and sealing applications
- Spline couplings
- High-performance bearings and bushings
- Locking fasteners for aerospace
- Pivot bushings on unison ring
PERFORMANCE CHARACTERISTICS:
- Long term performance at temperatures
up to 260°C (500°F) - Outstanding sealing characteristics when mated against metals
- Excellent unlubricated bearing and wear properties (bearing grades)
- Good electrical insulating properties
(unfilled grades)
