<p>PROBLEM TO BE SOLVED: To realize a manufacturing process wherein contamination or the increase of the cost can be avoided in the manufacture of a rubber plug, and at the same time, provide a plug body which has a sealing property and safety at a high level, and is especially suitable for transfusion. SOLUTION: This plug body for transfusion is equipped with a plastic supporting body, and a rubber plug which is supported by the supporting body. The rubber plug is formed of a thermoplastic elastomer obtained by dynamically vulcanizing a resin composition containing 3 to 20 wt.% of a polyolefin resin, 10 to 60 wt.% of a butyl rubber, 10 to 60 wt.% of a hydrogenated aromatic vinyl-conjugated diene compound block copolymer, the number average molecular weight of which is 150,000 or higher, and 20 to 60 wt.% of a mineral oil, with a vulcanizing agent.</p> |
