MULTILAYERED HEAT-RECOVERABLE ARTICLE, WIRE SPLICE, AND WIRE HARNESS

摘要

Provided are a multilayered heat-recoverable article which can suppress deterioration of a PVC insulated wire and flow of an adhesive layer and which is suitable for appropriately protecting the PVC insulated wire; and a wire splice and a wire harness, each including the multilayered heat-recoverable article. According to the present invention, a multilayered heat-recoverable article 1 includes a base material layer 10 and an adhesive layer 11 disposed on an inner side of the base material layer 10. The adhesive layer 11 does 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 article 1 is 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.
