More Information
Summary:A poly(arylene ether) composition includes a styrenic polymer, a flame retardant comprising an organophosphate ester, and a poly(arylene ether)-polysiloxane block copolymer reaction product. The poly(arylene ether)-polysiloxane block copolymer reaction product includes a poly(arylene ether)-polysiloxane block copolymer and a poly(arylene ether) homopolymer. The composition is useful for forming molded articles, including photovoltaic junction boxes and connectors. The composition exhibits stiffness and a good balance of flame retardancy, impact strength, flow, and heat resistance.
