<P>PROBLEM TO BE SOLVED: To provide a fluororesin molded article from which the concentration of eluted fluorine ions after being molded is reduced, to provide a method for producing the fluororesin molded article, with which the concentration of the eluted fluorine ions is reduced, and to provide a fluororesin composition. <P>SOLUTION: The method for producing the fluororesin molded article includes melt-molding a fluororesin in the presence of a fluorine-ion reducing compound. There are provided the molded article obtained by the method and the fluororesin composition. Ammonia, urea, a nitrogen compound capable of forming ammonia, and an alkali are preferable examples of the fluorine-ion reducing compound. There is also provided the molded article of a tetrafluoroethylene/perfluoro(alkylvinyl ether) copolymer in which the concentration of fluorine ions is ≤1 ppm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
