摘要： The present invention aims to provide an electric wire that is capable of being produced by extrusion molding and is excellent in heat resistance and crack resistance. The present invention relates to 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 the group consisting of a copolymer including a tetrafluoroethylene unit and a perfluoro(alkyl vinyl ether) unit and a copolymer including a tetrafluoroethylene unit and a hexafluoropropylene unit.

摘要： Provided is a novel modified fluororesin material having a low linear expansion coefficient, a material for a circuit board, a laminate for a circuit board, a circuit board, and a method for producing the modified fluororesin material. The modified fluororesin material contains a modified fluororesin. The modified fluororesin contains a tetrafluoroethylene unit, a modifying monomer unit based on a modifying monomer copolymerizable with tetrafluoroethylene, and a tertiary carbon atom. The tertiary carbon atom is present in an amount of 0.001 to 0.100 mol% of a total amount of the tetrafluoroethylene unit and the modifying monomer unit. The modified fluororesin material has a linear expansion coefficient at 20°C to 200°C that is 5% or more lower than that of a non-modified fluororesin material. The non-modified fluororesin material contains a tetrafluoroethylene unit and a modifying monomer unit based on a modifying monomer copolymerizable with tetrafluoroethylene and containing no tertiary carbon atom.
