  • Publication number: 20240026141
    Abstract: A fluororesin composition, and a molded article obtained from the fluororesin composition. The fluororesin composition containing: a non-melt-flowable fluororesin A having a history of being heated to a melting point thereof or higher; and a non-melt-flowable fluororesin B having no history of being heated to a melting point thereof or higher. The fluororesin composition contains a tetrafluoroethylene unit and a modifying monomer unit based on a modifying monomer copolymerizable with tetrafluoroethylene. Further, the fluororesin composition is a powder for compression molding excluding ram extrusion molding.
