The elastomer composition of the present invention comprises a thermoplastic elastomer composition which contains 20 to 80% by weight of component (A), 1 to 25% by weight of component (B), and 1 to 70% by weight of component (C): Component (A): at least one block copolymer selected from: a block copolymer having a polymer block derived from a vinyl aromatic compound and a polymer block derived from at least one selected from a conjugated diene and isobutylene; and a block copolymer obtained by hydrogenating the block copolymer; Component (B): a polypropylene resin containing component (B1): a modified polypropylene obtained by graft-modifying a polypropylene resin with a diene compound; and Component (C): a hydrocarbon softener for rubber.

Elastomer composition and medical container stopper formed by molding same

An object of the present invention is to provide a thermoplastic elastomer composition capable of molding a medical tube excellent in the transparency and kink resistance. The present invention is related to a thermoplastic elastomer composition including a hydrogenated block copolymer (A) wherein the copolymer has at least two polymer blocks P composed mainly of an aromatic vinyl compound unit and at least one polymer block Q composed mainly of a conjugated diene compound unit; the total content of aromatic vinyl compound units is from 8 to 25% by mass; and the copolymer contains a high-MFR hydrogenated block copolymer and a propylene polymer (B).

Thermoplastic elastomer composition, extrusion molded article, and medical tube

An assembly of the present invention for a syringe is composed of a barrel, made of cyclic polyolefin, which has a barrel body having a distal end part and a piercing needle which has a piercing needle tip at its distal end and is fixed to a piercing needle fixing portion of the barrel and a seal cap mounted on the barrel. The seal cap is formed of a thermoplastic elastomer composition containing as its main component a mixture of a styrene-based thermoplastic elastomer and a softener, for hydrocarbon-based rubber, which has a kinematic viscosity of 1 to 5,000 mmsat 100 degrees C. and a naphthenic carbon ratio (% CN) of not more than 20% when said naphthenic carbon ratio is measured by ring analysis.
