Also described are methods of forming the composition. The composition is useful for molding electrical and automotive components. | 06-23-2011 |
20110152431 | FLAME RETARDANT POLYAMIDE COMPOSITION, METHOD, AND ARTICLE - A composition is prepared by melt blending specific amounts of a polyamide, a flame retardant that includes brominated polystyrene, a polymeric flame retardant synergist, and a compatibilizing agent. The polymeric flame retardant synergist can be a poly(arylene ether), a poly(arylene ether)-polysiloxane block copolymer, or a mixture thereof The composition is useful for molding automotive and electrical parts. | 06-23-2011 |
20120029129 | POLYAMIDE/POLY(ARYLENE ETHER) COMPOSITION, ARTICLE, AND METHOD - A polyamide-poly(arylene ether) composition is prepared by melt blending specific amounts of components including a polyamide, a poly(arylene ether), a hydrogenated block copolymer of an alkenyl aromatic monomer and a conjugated diene, a compatibilizing agent, and partially saponified ester of a C | 02-02-2012 |
20120325083 | PISTON GUIDE RING COMPRISING POLYAMIDE-POLY(ARYLENE ETHER) COMPOSITION - A piston guide ring for use in a piston-cylinder assembly includes a compatibilized polyamide-poly(arylene ether) blend. The compatibilized polyamide-poly(arylene ether) blend includes about 35 to about 95 parts by weight polyamide and about 5 to about 65 parts by weight poly(arylene ether), based on 100 parts by weight total of the polyamide and the poly(arylene ether). The piston guide rings provide improved compressive strength at elevated operating temperatures, more isotropic mold shrinkage, and reduced moisture absorption compared to piston guide rings prepared from polyamide. | 12-27-2012 |
20130078465 | POLYAMIDE/POLYPHENYLENE ETHER FIBERS AND FIBER-FORMING METHOD - A fiber is prepared by melt extruding a composition including specific amounts of a polyamide and a polyphenylene ether along with a compatabilizer. Particular combinations produce fibers having a desirable combination of good tenacity and low denier per fiber. Compared to a fiber prepared from polyamide alone, the present fiber exhibits improved heat resistance and flame resistance. | 03-28-2013 |
20140065348 | POLYAMIDE-POLY(PHENYLENE ETHER) FIBER, ARTICLE, COMPOSITION, AND METHOD - A flame retardant polyamide fiber is prepared from a composition containing specific amounts of a polyamide, a poly(phenylene ether)-polysiloxane block copolymer reaction product, a flame retardant that includes a metal dialkylphosphinate, and a compatibilizing agent. The composition used to form the fiber can be prepared in a process that includes melt blending a portion of the polyamide with all the other ingredients to form an intermediate composition, and then melt blending the intermediate composition with the remainder of the polyamide. The composition has small disperse phase particles that facilitate its use to melt spin fibers. | 03-06-2014 |
