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 the constituent and a polymer block (b) derived from a monomer component other than isobutylene, and a thermoplastic polyurethane resin (B). |
