SHRINKPROOFING MATERIAL AND MOLDED BODY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a shrinkproofing material, which produces a fully shrinkproofing effect to a polyolefin-based resin or a rubber, and a resin molded body, to which the shrinkproofing material is employed. SOLUTION: On the outer periphery of a core wire 2 made of metallic wires, hot melt varnish mainly made of a modified polypropylene resin is coated and fired so as to provide a fusion bonded layer 3 in order to constitute a shrinkproofing material 1. A molded body is made by imbedding the shrinkproofing material 1 in a polyolefin-based resin or a rubber.
