RESIN COMPOSITION AND MEMBER COMPRISING SAID RESIN COMPOSITION

摘要

A resin composition which comprises 100 parts by weight of a thermoplastic elastomer containing an isobutylene based block copolymer comprising an isobutylene based polymer block and an aromatic vinyl based polymer block and 1 to 50 parts by weight of a polyolefin resin. The resin composition can provide a product exhibiting a low hardness, high loss property damping property and good gas permeability, and can be injection-molded with high and stable dimensional accuracy, and thus can be suitably used for producing an elastic member for an ink-jet printer, an insulator for a recording medium driving device, a gasket for HDD, a shock absorber for HDD, and the like.
