摘要： Medical tubes are well balanced in transparency, flexibility, heat resistance, scratch resistance and rubber elasticity.The medical tubes including a propylene polymer composition (A) that contains a polymer with propylene units, at least part of the polymer having an isotactic structure and the total of the propylene units of the polymer being in an amount of 65 to 82 mol % (the total of the structural units of the polymer in the composition is 100 mol %), and that satisfies the following (a1), (a2) and (b1): (a1) the modulus in tension is in the range of 5 to 25 MPa as determined in accordance with JIS K 6301; (a2) the penetration temperature is 120° C. or above as determined in accordance with JIS K 7196; and (b1) when a tube being made of the composition (A) and having an inner diameter of 2.1 mm, an outer diameter of 3.5 mm and a length of 20 cm is looped by inserting both ends thereof into a hollow jig having a hole 10 mm in diameter and 5 mm in height and, then, the both ends of the tube are pulled down until a kink occurs in the loop, the distance H from the upper surface of the jig to the upper end of the loop is not more than 60 mm.
