MULTILAYERED TUBE AND MEDICAL SUPPLY COMPRISING MULTILAYERED TUBE

摘要

A multi-layered tube is composed of at least two layers formed of different resin compositions containing a polypropylene resin and at least one copolymer selected from the group consisting of hydrogenated block copolymers obtained by hydrogenation of block copolymers formed of a polymer block from a vinyl aromatic compound and an isoprene and/or butadiene polymer block and a hydrogenated copolymer obtained by hydrogenation of a copolymer from a vinyl aromatic compound and butadiene. The multi-layered tube can be used as a multi-layered tube for medical use which is excellent in flexibility and anti-kinking properties, further, which has durability against sterilization with high-pressure steam, which is free from generation of any toxic gas when incinerated, and which is excellent in hot solvent bonding or solvent adhesion to other tube, and the like.
