Abstract: A thermoplastic molding composition comprising (1) a polyamide, (2) polytetrafluoroethylene and (3) an inert filler selected from the group consisting of silica and magnesium oxide is provided. The composition can be pressed and sintered, injection molded, compression molded, extruded or readily applied to a substrate by spraying, dipping or painting. It is self-lubricating and highly resistant to creep and wear, and is especially adapted for use as self-lubricating bearing surfaces or elements such as machine tool bed ways, gears, rollers, cams and the like.
