PTFE-based sliding material, bearing, and method for producing PTFE-based sliding material

摘要

A PTFE-based sliding material, wherein the porous sintered layer on the surface of backing metal is impregnated with baked PTFE, with one or both of the solid lubricant and wear-resistant additive together with fibrous PTFE forming an entangled fibrous PTFE structure, is used for a bearing of air-conditioner. Resistance of the bearing for local wear is required. Such wear resistance is to be enhanced. Carbides of an oligomer or polymer containing a hydrophilic group formed during baking are incorporated in the entangled structure of fibrous PTFE.
