摘要:
A fluorocopolymer with which the frequency of molding faults in electric wire covering molding can be reduced and which can give electric wires improved in crack resistance. The fluorocopolymer includes a tetrafluoroethylene-derived constituent unit as essential unit, and hexafluoropropylene-derived constituent unit and/or perfluoro(alkyl vinyl ether)-derived constituent unit. When the fluorocopolymer is molded into a film, the film has not more than 10000 fisheyes capable of enclosing a square with a side length of 44 μm and incapable of enclosing a square with a side length of 178 μm per 100 g and not more than 1000 fisheyes capable of enclosing a square with a side length of 178 μm per 100 g.
