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).

Resin composition for tubes and tube

An object of the present invention is to provide a thermoplastic elastomer composition which is highly flexible while maintaining vibration damping properties, as a feature of an isobutylene polymer, and is excellent in moldability and rubber-like properties, and also has particularly improved permanent compression set. The object is achieved by a thermoplastic elastomer composition comprising (A) a composition obtained by crosslinking an isobutylene polymer having an alkenyl group at the molecular ends with a hydrosilyl group-containing compound while melt-kneading in the presence of at least one kind selected from an aromatic vinyl-containing thermoplastic elastomer and an olefinic resin, and (B) at least one kind selected from the group consisting of an aromatic vinyl-containing thermoplastic elastomer and an olefinic resin.
