(57) [Abstract] [PROBLEMS] To provide a heat-shrinkable tube made of a fluorine-containing elastomer which is excellent in toughness, eliminates the generation of die residue during extrusion, and can shrink at low temperature, and a method for producing the same. [Structure] 100 parts by weight of a resin component containing a tetrafluoroethylene-propylene-based copolymer and vinylidene fluoride-propylene hexafluoride copolymer, and 0.5 parts by weight or more of a crosslinking aid are added. It consists of a composition. Such a composition is molded into a tube shape, and the tube-shaped molded body is crosslinked by irradiation with ionizing radiation, and then expanded and fixed. |
