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.
