Abstract: A heat-resistant electric wire including a core wire and a coating that covers the core wire. The coating is formed from a modified fluorine-containing copolymer that is obtained by irradiating a copolymer with radiation at an exposure of 250 kGy or lower at a temperature of not higher than the melting point of the copolymer. The copolymer is at least one copolymer selected from a copolymer including a tetrafluoroethylene unit and a perfluoro(alkyl vinyl ether) unit and a copolymer including a tetrafluoroethylene unit and a hexafluoropropylene unit.

Abstract: A method for producing a tube, which includes: extruding a melt-fabricable fluororesin from a mold of an extruder into a form of a tube, leading the extruded melt-fabricable fluororesin to a cooling device to cool the extruded melt-fabricable fluororesin, and winding a resulting cooled tube onto a winding reel using a winding device. A gas is fed from a head end of the tube wound onto the winding reel into a hollow of the tube, the gas in the hollow is allowed to pass through a gas-introducing entrance of the mold and then through a gas-discharging hole of the mold to discharge the gas outside, thereby allowing the gas to flow along the hollow, and an internal pressure of the hollow is kept higher than atmospheric pressure and lower than 0.5 kgf/cm2.
