VESPEL® SP-211

Vespel® SP-211 is a polyimide grade offering exceptional thermal and chemical resistance. This material is ideal for applications requiring resistance to aggressive chemicals and long-term thermal stability. Minimum static coefficient of friction over a wide range of operating conditions, as well as lowest wear up to 150°C. It is used in the aerospace, automotive, chemical processing and other industries with applications requiring a low coefficient of friction and moderate wear. For example: bushings, thrust washers.
