PROBLEM TO BE SOLVED: To provide a tube prepared from a thermoplastic plastic which has a high biocompatibility and a moderate flexibility and stretch recovery property. SOLUTION: The tube comprises a hydrogenated styrene butadiene block copolymer, a paraffin-based oil and a polypropylene resin. Preferably, the blending proportion of the hydrogenated styrene butadiene block copolymer is from 30 to 40 wt.%, the blending proportion of the paraffin-based oil is from 40 to 50 wt.% and the blending proportion of the polypropylene resin is from 10 to 30 wt.%. Preferably, the hardness of the tube is from 50 to 85. |
