Patent number: 6977105Abstract: A multi-layered tube composed of at least two layers, each formed from a different resin, e.g. resin (I) or resin (II). Resin (I) contains 5 to 40 mass % of a polypropylene resin and 95 to 60 mass % of at least one hydrogenated copolymer. Resin (II) contains 45 to 100 mass % of a polypropylene resin and 55 to 0 mass % of a hydrogenated copolymer. The multi-layered tubes may be used in the field of medicine and provide tubing which is excellent in transparency, flexibility and anti-kinking properties, and which is durable during sterilization procedures with high-pressure steam. The multilayer tubing may also be safely disposed of as it generates no toxic gases, such as dioxin, when incinerated. The multilayered tubing has excellent connectability and may be bonded to other tubing using hot solvent bonding or solvent adhesion. The multilayered tubing 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.Type: GrantFiled: September 22, 2000Date of Patent: December 20, 2005Assignees: Kuraray Co., Ltd., Kawasumi Laboratories, Inc.Inventors: Yukihiro Fujieda, Masayasu Ogushi, Motohiro Fukuda, Toshiyuki Zento, Koichi Wada, Toshiji Ichikawa, Akira Ishida
