Resin composition for tubes and tube |
摘要 |
The present invention has its object to provide a resin composition for tubes excellent in balance among wear resistance, flexibility, gas permeation resistance and low resilience (pliability). The object is accomplished by a resin composition for tubes which comprises an isobutylene block copolymer (A) constituted of a polymer block (a) derived from isobutylene as a main constituent and a polymer block (b) derived from a monomer component other than isobutylene as a main constituent, and a thermoplastic polyurethane resin (B). |
