  • Publication number: 20190351639
    Abstract: A heat-resistant two-layer heat-shrinkable tube including an outer layer and an inner layer, and a method for covering an object to be covered with the heat-resistant two-layer heat-shrinkable tube. The outer layer consists of a cross-linked product of a resin composition containing a resin, such as a tetrafluoroethylene-ethylene copolymer with a melting point of 210° C. or more and 260° C. or less, and a cross-linking aid. The outer layer thermally shrinks at 250° C. or more and 280° C. or less. The inner layer consists of a hot-melt adhesive composed mainly of an acid-modified tetrafluoroethylene-ethylene copolymer or the like and having a shear viscosity of less than 10000 Pa·s at 250° C. and at a shear rate of 10 s?1.
