Vespel® polyimide shapes by DuPont are available online

Vespel® polyimide shapes are produced from advanced polymers developed by DuPont. Vespel® polyimide combines High-Temperature Performance, Natural Lubricity, Dimensional Stability, Chemical Resistance, Creep Resistance, and more.

Vespel® does not outgas or melt at any temperature & performs well in vacuum applications, even in extremely low cryogenic temperatures.

Vespel® polyimide is available in five standard grades:

•Vespel® SP-1 - Unfilled. Maximum strength & elongation: lowest modulus & thermal conductivity: optimum electrical properties.

•Vespel® SP-21 - 15% graphite (by weight). Enhances inherent wear resistance, improves long term thermal stability.
•Vespel® SP-22 - 40% graphite (by weight). Gives low coefficient of thermal expansion. Maximum creep resistance.
•Vespel® SP-211 - 15% graphite and 10% TEFLON® fluorocarbon resin (by weight). Lowest static friction.
•Vespel® SP-3 - 15% MoS2 (by weight). Best wear performance in dry environments. Dupont Vespel®
