LINED PIPES AND FITTINGS, ASSOCIATED FORMING METHOD, AND METHOD OF IMPROVING THE CHLORINE RESISTANCE OF HIGH DENSITY POLYETHYLENE PIPES

A lined pipe or fitting includes an outer layer containing high density polyethylene, and an inner layer containing a blend of poly(phenylene ether), polystyrene, and, optionally, a hydrogenated block copolymer. Relative to corresponding pipes and fittings made from high density polyethylene alone,...

More Information
Summary:A lined pipe or fitting includes an outer layer containing high density polyethylene, and an inner layer containing a blend of poly(phenylene ether), polystyrene, and, optionally, a hydrogenated block copolymer. Relative to corresponding pipes and fittings made from high density polyethylene alone, the lined pipes and fittings exhibit improved resistance to chlorine and chlorine derivatives.
