To provide a molding material for a fluororesin that has an excellent electrical properties especially dielectric dissipation factor even in a microwave range, can mold at a lower pressure because of a low molecular weight polymer, is excellent in surface smoothness, and is useful as a material e.g. coating material such as a coaxial cable for equipment using microwave in a satellite communication or a mobile phone base station or the like.
The molding material for a tetrafluoroethylene resin excellent in high-frequency electric properties provides a resin that has ≤2.2 of permittivity at 12 GHz, ≤1.60×10-4 of a dielectric dissipation factor and ≥2.192 and <2.3 of standard specific gravity. For the tetrafluoroethylene resin, a homopolymer of tetrafluoroethylene or a copolymer composed of tetrafluoroethylene of 99.9-99.9999 mol% and a specified fluoromonomer of 0.0001-0.1 mol% is desirably used.
