摘要
PROBLEM TO BE SOLVED: To provide an extrusion-molded two-layer tube for medical care in which suitable flexibility is possessed, product handleability is excellent, and product producibility can be maintained.SOLUTION: There is provided an extrusion-molded two-layer tube for medical care that is inserted in a resin-made member to be adhesion-joined for medical care from the outside and adhesion-joining is performed by blocking by heating. The extrusion-molded two-layer tube for medical care is characterized in that an inner layer is formed of polyethylene, polypropylene, a styrenic elastomer, an olefinic elastomer, or a mixture of them, or a raw material which contains them as main components, which is a raw material having a melting point of at most the heating temperature, and an external layer is formed of polypropylene, a styrenic elastomer, an olefinic elastomer, or a mixture of them, or a raw material which contains them as main components, which is a raw material having a melting point exceeding the heating temperature, and a radial thickness of an external layer is 2%-5% based on a radial thickness of the entire tube.
