MOLDING MATERIAL FOR SEALING MEMBER OR BEARING MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a molding material for use in a sealing member or a bearing which reduces not only the amt. of abrasion of the counterpart member but also the amt. of abrasion of the resin itself and enhances the limit PV value. SOLUTION: This material comprises (A) 50-94 wt.% of a polytetrafluoroethylene powder having an average particle size of 120μm or less, (B) 40-5 wt.% of an oxidized polyarylene sulfide type heat-resistant resin powder and (C) 10-1 wt.% of a solid lubricant other than the oxidized polyarylene sulfide type heat-resistant resin powder. (B) The heat-resistant resin powder is desirably polyphenylene suLfone.
