Abstract
It is an object of the present invention to provide a resin composition which has a low hardness, is favorable in high loss properties (vibration absorbing properties) and gas permeation resistance, is excellent in injection moldability, thereby enabling itself to be injection molded with stable dimensional accuracy, and which is particularly suitable for constituting an elastic member for an ink jet printer, an insulator for a recording medium drive, a gasket for an HDD and an impact absorbing material for an HDD. The above object has been achieved with a resin composition which comprises 100 parts by weight of a thermoplastic elastomer containing an isobutylenic block copolymer composed of isobutylenic polymer blocks and aromatic vinylic polymer blocks, and 1 to 50 parts by weight of a polyolefin resin.
