FLAME-RETARDANT HALOGEN-FREE POLY(PHENYLENE ETHER) COMPOSITIONS

摘要

Disclosed are polymer compositions, comprising: (a) 10 to 40 weight percent of a poly(phenylene ether)-polysiloxane copolymer; (b) 5 to 25 weight percent of a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene; (c) 0 to 10 weight percent of a polybutene; (d) 30 to 60 weight percent of magnesium hydroxide; (e) 0 to 10 weight percent of an anti-UV agent; (f) 1 to 40 weight percent of a copolymer of ethylene and a C3-C12 alpha-olefin; and (g) 0 to 30 weight percent of a polyolefin homopolymer.
