Abstract:
A product having reduced friction and improved abrasion resistance comprising:a fluoroplastic molded material containing a modified fluoroplastic prepared by applying ionizing radiation to a fluoroplastic (I) heated at the melting point or a higher temperature under an inert gas atmosphere having a 10 torr or less oxygen concentration within a range of irradiation doses of from 1 KGy to 10 MGy; and an unmodified fluoroplastic (II), said fluoroplastic (II) is selected from the group consisting of tetrafluoroethylene-perfluoro-(alkyl vinyl ether)-based copolymers and tetrafluoroethylene-hexafluoropropylene copolymers, and said fluoroplastic (I) is selected form the group consisting of tetrafluoroethylene-based polymers, tetrafluoroethylene-perfluoro-(alkyl vinyl ether)-based copolymers, and tetrafluoroethylene-hexafluoropropylene copolymers.
