Abstract
A composition is prepared by melt blending specific amounts of polyamide, acid-functionalized poly(phenylene ether), polyimide-polysiloxane block copolymer, and metal dialkylphosphinate. The composition, which exhibits improved flame retardancy and tensile modulus relative to known blends of poly(phenylene ether), polyamide, and polyimide, is useful for forming electrical components, such as photovoltaic junction boxes and connectors, inverter housings, automotive electrical connectors, electrical relays, and charge couplers.
Description
Background technique [0001] Polyphenylene ethers are a class of plastics known for their excellent water resistance, dimensional stability, and inherent flame retardancy. Properties such as strength, hardness, chemical resistance, and heat resistance can be tailored by blending it with a variety of other plastics to suit a wide variety of consumer products such as plumbing fixtures, electrical boxes, automotive components, and wire and cables Insulation needs. [0002] Blends of polyphenylene ethers with polyamides and polyimides are known. See, for example, Japanese Patent Application Publication No. JP10007900 A to Takatani, which describes blends in which polyphenylene ether and polyimide are dispersed in a continuous polyamide phase. The Takatani compositions offer improved compatibility of polyphenylene oxide and polyimide, but their flame retardancy and tensile modulus are critical for some applications such as photovoltaic junction boxes and connectors, and mass trans...
