METHOD FOR PRODUCING FLUOROPLASTIC POWDER, FLUOROPLASTIC POWDER, AND COMPOSITION CONTAINING FLUOROPLASTIC POWDER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a fluoroplastic powder wherein an unmelted perfluoro melt-processable resin is irradiated with a radiation to obtain a fluoroplastic-containing layer being excellent in nontackiness, staining resistance, etc., and improved in durability. SOLUTION: The method comprises irradiating the unmelted perfluoro melt- processable resin with a radiation at an absorbed dose of 10-500 kGy in the presence of oxygen. COPYRIGHT: (C)2004,JPO
