Use of a product with improved abrasion resistance

摘要

A product having reduced friction and improved abrasion resistance comprises a formed resin containing at least one fluorine-contained polymer which is exposed to an ionizing radiation. The formed resin may include from 1 to 100 weight percent of the fluorine-contained polymer in the form of powder, and from 99 to 0 percent of a high molecule polymer which is not exposed to the ionizing radiation. The fluorine-contained polymer is preferably exposed to the ionizing radiation for a total dose of from 1 KGy to 10 MGy in the absence of oxygen at a temperature not lower than the melting point of a starting fluorine-contained polymer.
