Beschreibung
Zusammenfassung:	A sliding member excellent in cavitation resistance and friction properties which has a sliding surface composed of a resin composition comprising a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin and a polytetrafluoroethylene having a molecular weight of 5,000,000 to 15,000,000 and optionally a solid lubricant, wherein the proportion of the tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin is 1 to 50% by volume based on the volume of the resin composition and the proportion of the solid lubricant is 0.5 to 10% by volume based on the volume of the resin composition. The addition of the solid lubricant results in an enhancement of friction properties and the use of an exfoliated graphite as the solid lubricant brings about a further enhancement of friction properties.
