    Abstract: PURPOSE:To obtain a heat-shrinkable tube capable of covering and hermetically sealing various cover members and excellent in heat resistance and adhesive capacity by forming the heat-shrinkable tube so as to have a double-layer structure consisting of an outer layer composed of crosslinked polyethylene and an inner layer composed of a compsn. prepared by mixing a predetermined amt. of a polyamide copolymer with a carboxyl group-containing an ethylene copolymer. CONSTITUTION:As an outer layer material, crosslinkable polyethylene or crosslinkable silane grafted polyolefin is used. As an inner layer material, a compsn. prepared by compounding 1-50 pts.wt. of a polyamide copolymer with 100 pts.wt. of a carboxyl group-containing ethylene copolymer is used. As the carboxyl group-containing ethylene copolymer, an ethylene/butene-1 copolymer and/or an ethylene/propylene copolymer and an ethylene/methacrylic acid/acrylic ester copolymer all of which are modified with maleic anhydride are pref. A tube is molded using the outer and inner layer materials to be subjected to electron beam crosslinking, chemical crosslinking or water crosslinking to obtain a heat-shrinkable tube of which the outer layer is crosslinked.
