Long fluororesin films include tetrafluoroethylene resin, tetrafluoroethylene perfluorovinyl ether cofi, tetrafluoroethylene hexafluoropropylene copolymer, tetrafluoroethylene ethylene copolymer, and trifluorochloride. Films of general fluororesins such as ethylene resins can be used. The thickness of the film is preferably O, OO5~0.5~, and if necessary, the fluororesin may contain inorganic fillers such as aluminum hydroxide, talc, silica, alumina, calcium carbonate, and magnesium carbonate, glass fiber chips, and asbestos. It is also possible to add fibrous fillers such as wood flour, pulp, cotton flour, etc. Single, alloy, or composite foils of copper, aluminum, iron, nickel, zinc, etc. are used as long metal foils, and if necessary, an adhesive layer is provided on one side of the metal foil to further improve adhesion. You can also do so. The elongated laminate can be continuously heated and pressed by a double belt method or the like, and the curing temperature varies depending on the resin composition, but the pressure is preferably 1 to 40 kg/all.
なお長尺積層体は成形直前に予熱することが望ましい。Note that it is desirable to preheat the elongated laminate immediately before molding.
