Harzbeschichtetes Rohr

摘要

Disclosed is a resin-coated pipe, which is obtainable by extrusion coating a tubular base with a resin composition comprising 5 to 30 % by weight of a component A and 95 to 70 % by weight of a component B. Component A: an ethylene- alpha -olefin copolymer resin in which the melt flow rate at a temperature of 190 DEG C and under a load of 2.16 kg is 0.01 to 50 g per 10 min., the density is 0.910 g/cm<3> or below, and the maximum fusion peak temperature as measured by a differential scanning calorimeter is 60 DEG C or above. Component B: crystalline polypropylene, in which the melt flow rate at a temperature of 190 DEG C and under a load of 2.16 kg is 0.1 to 10 g per 10 min. The resin-coated pipe, using the above resin composition which is excellent in processibility, is excellent in the mechanical strength, normal and low temperature impact resistance, heat resistance, chipping resistance and coating surface appearance.
