The resin composition for tubes excellent in the balance of abrasion resistance, flexibility, gas permeability, and low repulsion (elasticity) is provided. Isobutylene block copolymer (A) composed of a polymer block (a) having isobutylene as a main component and a polymer block (b) having a monomer component having a heterogeneous component with isobutylene (A) and a thermoplastic polyurethane system It is achieved by the resin composition for tubes which consists of resin (B).n n n PVC Alternative Materials Thermoplastic Polyurethane Resin, Isobutylene Block Copolymer, Resin Composition for Tube |
