MIXED RESIN COMPOSITION AND HEAT-SHRINKABLE TUBE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a heat-shrinkable tube that has both high abrasion resistance and high oil resistance while maintaining flexibility.SOLUTION: A mixed resin composition constituting the heat-shrinkable tube includes an urethane rubber produced by reacting a polyester polyol with an isocyanate, a low-density polyethylene resin and carbon black. The low-density polyethylene resin and carbon black are blended in an amount of 10-60 pts.wt. and 20-120 pts.wt., respectively, based on 100 pts.wt. of the urethane rubber.
