Overview
DuPont™ Vespel® SCP-5050 is a new and innovative polyimide composition.
Vespel® SCP-5050 improves high temperature and wear resistance compared to conventional polyimides allowing replacement of metal and graphite in more applications.
The Vespel® SCP-5050 proprietary composition is designed to offer high stiffness and a low coeffecient of thermal expansion (CTE).
Use of Vespel® SCP-5050 enables:
- More efficient and durable systems
- Increased performance
- Reduced maintenance costs
