TETRAFLUOROETHYLENE/HEXAFLUOROPROPYLENE COPOLYMER, AND ELECTRIC WIRE

摘要

Provided is a tetrafluoroethylene/hexafluoropropylene copolymer which is less likely to form a lump, or is less likely to form a large lump even if a lump is formed, during the formation of an electric wire. The tetrafluoroethylene/hexafluoropropylene copolymer has a melt flow rate measured at 372°C of 35.0 to 45.0 g/10 minutes and a swell of -8.0% to 5.0%, the sum of the numbers of -CF 2 H groups and unstable end groups being 120 or less per 1 × 10 6 carbon atoms.
