HEAT-RESISTANT FLAME-RETARDANT RESIN COMPOSITION, INSULATED ELECTRIC WIRE, AND TUBE

WIPO Patent Application WO/2014/010508

A1

Provided is a heat-resistant flame-retardant resin composition which is a resin composition made by blending an inorganic filler and/or a flame retardant to a mixture of a tetrafluoroethylene-α-olefin copolymer and a random polypropylene and by further irradiating the mixture with an ionizing radiation, the heat-resistant flame-retardant resin composition being characterized in that the mixing ratio between said tetrafluoroethylene-α-olefin copolymer and said random polypropylene is from 60:40 to 90:10 (mass ratio), the heat-resistant flame-retardant resin composition being inexpensive and having excellent insulating properties, heat resistance, flexibility, and flame retardancy as well as mechanical strength, such as cut-through properties and crimping workability, in a balanced manner. Also provided are an insulated electric wire having an insulating sheath made of said resin composition, and a tube made of said heat-resistant flame-retardant resin composition.
