Vespel® SP-211 has 10% PTFE and 15% graphite by weight added to the base resin for the part coefficient of friction over a wide range of operating conditions. It also has excellent wear resistance up to 300 degrees F (149 degrees C). Typical applications include sliding or liner bearings as well as many wear and friction uses.
