PI - Polyimide
Vespel® is a high-performance polyimide (PI). In demanding applications it surpasses other technical materials.
The strengths of this product family include its outstanding temperature resistance. Because Vespel® does not melt, its area of use ranges from cryogenic to very high temperatures. Whether lubricated or non-lubricated, this high-performance polyimide also offers high wear resistance and exceptionally high dimensional stability and creep resistance.
Vespel® is available in the form of finished or semi-finished parts. Typical applications include anti-friction bushes, thrust washers, valve seats and insulators in the automotive, aerospace and semiconductor industries as well as general machine construction.
