Patent ID: 8192814

Claim:
A tube comprising a molded article of a resin composition, wherein the resin composition comprises: (a) a hydrogenated block copolymer having a glass transition temperature, T g (a), of from −45 to 30° C. and comprising, in reacted form, a polymer block (A) constituted mainly from an aromatic vinyl compound unit and a polymer block (B) constituted mainly from a 1,3-butadiene unit or constituted mainly from an isoprene unit and a 1,3-butadiene unit, wherein a content of the polymer block (A) is from 5 to 40% by mass based on a total mass of (a) and the polymer block (B) has a hydrogenation rate of 70% or more; (b) a hydrogenated block copolymer having a glass transition temperature, T g (b), of less than −45° C. and comprising, in reacted form, a polymer block (C) constituted mainly from an aromatic vinyl compound unit and a polymer block (D) constituted mainly from a 1,3-butadiene unit or constituted mainly from an isoprene unit and a 1,3-butadiene unit, wherein a content of the polymer block (C) is from 10 to 40% by mass based on a total mass of (b) and the polymer block (D) has a hydrogenation rate of 80% or more; and (c) a polyolefin-based resin having an ethylene content of from 22 to 30%, wherein the polyolefin-based resin (c) is selected from the group consisting of (i) a copolymer of propylene and ethylene and (ii) a mixture of a compolymer of propylene and ethylene and a propylene homopolymer, wherein a mass ratio of (a) to (b), (a)/(b), is from 50/50 to 95/5, and a mass ratio of (c) to a sum of (a), (b), and (c), (c)/((a)+(b)+(c)), is from 10/100 to 60/100.
