  • Patent number: 10843432
    Abstract: A multilayer water pipe for mining operations has an outer layer and an inner layer. The inner layer of the multilayer water pipe includes a composition containing a poly(phenylene ether), a hydrogenated block copolymer of an alkenyl aromatic monomer and a conjugated diene, optionally, a homopolystyrene, a rubber-modified polystyrene, or a combination comprising at least one of the foregoing, and a flame retardant comprising an organophosphate ester. The outer layer of the multilayer water pipe includes a composition containing a high density polyethylene, an antistatic agent, a flame retardant, and a flame retardant synergist. The multilayer water pipe exhibits a desirable balance of impact strength, tensile strength, burst pressure resistance, static pressure resistance, flame retardancy, and outer surface electrical resistance.
