PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer resin composition which has high gas barrier properties, compressive deformation resistance in a high-temperature environment, flexibility and mechanical strength that are required for a material of a medical syringe gasket and a material of plugs of a bottle for chemical liquid preservation and a bottle for food preservation, has excellent moldability, and can enhance productivity.SOLUTION: A thermoplastic elastomer resin composition contains: 100 pts.mass of a resin composition which includes 20-80 mass% of (a) a crosslinked elastic body having a structural unit derived from isobutylene and 80-20 mass% of (b) one or more kinds selected from the group consisting of (b1) a hydrogenated product of a block copolymer of an aromatic vinyl compound and a conjugated diene compound and (b2) a block copolymer of an aromatic vinyl compound and isobutylene, where the total of the above described component (a) and the above described component (b) is 100 mass%; and 5-50 pts.mass of (c) a polyolefin resin.SELECTED DRAWING: Figure 1 |
