摘要：
A PTFE resin composition, which comprises PTFE resin, and metal carbide powder having a Vickers hardness of 1,200HV, or more, and which preferably further contains an inorganic filler other than the metal carbide powder, for example, carbon fibers, glass fibers, etc., has an improved abrasion resistance, when molded into resin seal rings, etc., by reducing a self-abrasion amount of the resin against hard mating metals having a rough surface (Rz of about 6.3 to about 9.0 according to JIS B0601-1994), and by polishing the mating material roughness rapidly.
