Abstract: A composition for injection molding includes specific amounts of a poly(phenylene ether), a first hydrogenated triblock copolymer, a second hydrogenated triblock copolymer, a polypropylene, a polybutene, an ethylene/1-octene copolymer, and a flame retardant. At least one of the first and second hydrogenated triblock copolymers has a pre-hydrogenation vinyl content of 50 to 100 mole percent, based on moles of incorporated polybutadiene. Injection molded articles prepared from the composition include cable connectors and their parts.

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.

Abstract: A water pipe for mining operations includes a composition including a poly(phenylene ether), a hydrogenated block copolymer of an alkenyl aromatic monomer and a conjugated diene, an organophosphate ester, a phosphazene or a combination thereof, and a brominated polystyrene. Each component is present in the composition in a particular amount defined herein. The water pipe can be made by a method including forming the composition by melt-mixing the components of the composition, and extruding the composition through an annular die to provide the water pipe.

Abstract: A poly(phenylene ether) composition includes specific amounts of a poly(phenylene ether), a hydrogenated block copolymer of an alkenyl aromatic monomer and a conjugated diene, a polypropylene or a polyethylene, a low molecular weight polybutene, a flame retardant, a liquid ultraviolet absorbing agent, and a poly(alkylene oxide). The composition can be useful as an insulation or jacketing material for wires and cables, where the insulation and jacketing materials including the composition can have reduced surface blooming.

Abstract: A composition includes specific amounts of a poly(phenylene ether), a hydrogenated block copolymer, a polyolefin, a flame retardant, and a hindered amine light stabilizer, and the composition minimizes or excludes benzotriazole ultraviolet absorbing agents. The composition exhibits desirable color stability on exposure to ultraviolet radiation, while reducing or eliminating migration of ultraviolet absorber to the surface of an insulated conductor or jacketed cable, and reducing or eliminating staining in the presence of metallic copper. The composition is useful for extrusion coating and injection molding.
