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 method of making an enhanced magnet wire insulation suited for an electric submersible motor application is described. The method includes drawing copper magnet wire to size and cleaning the copper magnet wire. The method includes pulling the copper magnet wire through a polyimide wrap machine to produce wrapped copper magnet wire and placing the wrapped copper magnet wire around a spool. The method includes heating the wrapped copper magnet wire by unspooling the wrapped magnet wire through a tube comprising an induction coil and removing moisture from the heated, wrapped copper magnet wire by creating at least a partial vacuum inside the tube. The method includes redrawing the wrapped copper magnet wire through an extrusion mold after moisture is removed. The method includes applying molten PEEK to the wrapped copper magnet wire to produce enhanced magnet wire and winding the enhanced magnet wire into an induction motor.
Abstract:
A composition contains specific amounts of a poly(phenylene ether), a hydrogenated block copolymer of an alkenyl aromatic monomer and a conjugated diene, a flame retardant that includes an organophosphate ester with a melting point of 60 to 150 º C, and an ultraviolet absorbing agent. The high-melting organophosphate ester permits reduction of the ultraviolet absorbing agent content, which in turn reduces color shift under storage conditions. The composition is useful as an insulating material and a jacketing material for wire and cable.
Abstract:
A foamed thermoplastic material includes a thermoplastic material exhibiting, in its unfoamed state, a particular flammability index, flame growth rate, and specific extinction area. The foamed thermoplastic material further includes a plurality of cells having a number average mean diameter of 5 to 150 micrometers present in an amount effective to provide the foamed thermoplastic material with a density that is 10 to 90 percent of the density of the unfoamed thermoplastic material. The foamed thermoplastic material exhibits a desirable tensile elongation and dielectric constant. A process for forming the foamed thermoplastic material, articles including the foamed thermoplastic material, and an article-forming process are also described.
Abstract:
Adhesive compositions are described that significantly improve the adhesion of polymer overmold compositions to metal substrates in polymer-metal junctions. The adhesive compositions include one or more poly(aryl ether) polymers, where each of the poly(aryl ether) polymers is, independently, a poly(aryl ether sulfone) polymer or a poly(aryl ether ketone) polymer. The overmold composition includes at least one poly(aryl ether ketone) polymer. Polymer-Metal junctions can be formed by, for example, dip-coating, spin-coating, extruding, or injection molding the adhesive composition and/or the overmold composition onto the metal substrate. Desirable applications settings for the polymer-metal junctions described include, but are not limited to electrical wiring.
