PROBLEM TO BE SOLVED: To provide a flexible tube for medical use that generates little dioxins when the tube is disposed and burnt, is excellent in environmental adaptability, and is low in impact resilience. SOLUTION: This tube for medical use is obtained by co-extruding a thermoplastic material (A) composed of a styrene-based block copolymer, etc., and a thermoplastic polyolefin (B), such as the polybutadiene. This tube has a multiphase structure in which at least one or more phases composed of the thermoplastic material (A) exist in the cross section of the tube cut perpendicularly to the axial direction of the tube. In addition, this tube has the maximum angle restoring amount of 95-105%. |
