Abstract

A multilayered heat-recoverable articleincludes a base material layerand an adhesive layerdisposed on an inner side of the base material layer. The adhesive layerdoes not flow at a temperature of 135° C. and includes a thermoplastic resin and a viscosity characteristics modifier composed of at least one selected from the group consisting of silica, an organically treated layered silicate, and a deterioration inhibitor. In the case where the multilayered heat-recoverable articleis used to cover an insulated electrical wire which includes a conductor and a polyvinyl chloride layer provided on the outer periphery thereof, cracks do not occur in the polyvinyl chloride layer under heating conditions at 135° C. for 200 hours.
