Vespel® SP-211
Vespel® SP-211 contains 10% PTFE and 15% graphite by weight. If you need an even lower coefficient of friction, then Vespel® SP-211 will be the best choice for you. This grade guarantees excellent wear resistance up to 149 °C. Any application that suffers from wear and friction, like sliding or liner bearings, will benefit greatly from the advantages of Vespel® SP-211.
