Abstract
A water pipe for mining operations has an outer diameter of 20 to 200 millimeters and a wall thickness of 2 to 20 millimeters. The water pipe includes a composition containing 58 to 82 parts by weight poly(phenylene ether), 8 to 18 parts by weight of a hydrogenated block copolymer of an alkenyl aromatic monomer and a conjugated diene, 0 to 15 parts by weight of polystyrene selected from the group consisting of homopolystyrenes, rubber-modified polystyrenes, and combinations thereof, and 10 to 20 parts by weight of a flame retardant comprising an organophosphate ester, wherein parts by weight values are based on 100 parts by weight total of the poly(phenylene ether), the hydrogenated block copolymer, the polystyrene, and the flame retardant. The water pipe exhibits a desirable balance of impact strength, tensile strength, burst pressure resistance, static pressure resistance, and flame retardancy.
