PURPOSE: To provide a tubular molding that keeps excellent flexibility and retains low-temperature impact resistance even when molded at a high speed and whose surface does not become sticky when used for a long time at high temperatures. CONSTITUTION: This tubular molded item is made from a polyamide resin composition made up to (A) 100 pts.wt. polyamide 11 resin and/or polyamide 12 resin, (B) 3 to 10 pts.wt. modified polyolefin resin which is a graft polymer prepared by grafting an olefin copolymer whose major component is an ethylene component and/or a propylene component with anα,β-unsaturated carboxylic acid or its derivative, and (C)3 to 25 pts.wt. plasticiser. |
