TETRAFLUOROETHYLENE/HEXAFLUOROPROPYLENE COPOLYMER, AND ELECTRIC WIRE

摘要

Provided is a tetrafluoroethylene/hexafluoropropylene copolymer in which lumps do not easily form during wire molding, and in which, even if lumps do form, large lumps do not easily form. The tetrafluoroethylene/hexafluoropropylene copolymer is characterized by having: a melt flow rate measured at 372°C of 35.0 to 45.0 g/10 minutes, swells of -8.0 to 5.0%, and a total of not more than 120 -CF2H groups and unstable terminal groups per 1×106 carbon atoms.
