FLUORINE RESIN MOLDED ARTICLE AND PRODUCTION OF SAME

摘要

[Object] To provide a fluororesin molded article having a lowered concentration of eluted fluorine ions subsequent to molding, and to provide a method for producing a fluororesin molded article, a fluororesin molded article, and a fluororesin composition whereby the concentration of eluted fluorine ions is lowered. [Means] A method for producing a fluororesin molded article in which fluororesin is melt-molded in the presence of a fluorine ion lowering compound, the molded article obtained thereby, and a fluororesin composition. Ammonia, urea, nitrogen compounds that generate ammonia, and alkalis are preferred examples of the fluorine ion lowering compound. The present invention also offers a molded article formed from tetrafluoroethylene/perfluoro(alkylvinyl ether) that has a fluorine ion concentration of 1 ppm or less.
