    Abstract: A tetrafluoroethylene/hexafluoropropylene copolymer has improved moldability in melt extrusion molding, especially with significant reduction of defects in high-speed extrusion coating of an electrical wire. The process for producing a tetrafluoroethylene/ hexafluoropropylene copolymer, comprises: polymerizing at least tetrafluoroethylene and hexafluoropropylene and optionally a third monomer so that a melt flow rate at 372 degree C of the copolymer during the polymerizing changes from the range from 0.05 to 5.0 g/ 10 minutes to the range from 10 to 60 g/ 10 minutes. The tetrafluoroethylene/hexafluoropropylene copolymer can be used in an electrical wire as a coating on a conductive core.
