| 摘要 |
The present invention provides a fluororesin composition which is improved in moldability in melt extrusion molding and, in particular, makes it possible to markedly reduce molding defects even when the extrusion molding for covering electric wires is carried out at a high speed. The present invention is a fluororesin composition comprising a tetrafluoroethylene/hexafluoropropylene-based copolymer and 0.01 to 3 parts by mass per 100 parts the copolymer of a polytetrafluoroethylene having a standard specific gravity of 2.15 to 2.30, and being obtained by mixing an aqueous dispersion of the tetrafluoroethylene/hexafluoropropylene-based copolymer with an aqueous dispersion of the polytetrafluoroethylene, causing coagulation, drying the polymer mixture and melt-extruding the same.
