Abstract
A sheet includes: a composition comprising about (60) to about (85) weight percent of polyphenylene, about (0) to about (10) weight percent of polystyrene, about (10) to about (20) weight percent of a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, about (3) to about (10) weight percent of an aryl salicylate, and optionally, a flame retardant additive.
Claims17
A composition, comprising:
- 67.90 to 72.6 weight percent of poly(phenylene ether),
- 15 to 20 weight percent of a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene,
- 4.7 to 5 weight percent of polysalicylate acetate, and
- 5 to 9.5 weight percent of a phosphorous-containing flame retardant additive, percentages based on 100 parts by weight total of the poly(phenylene ether), the hydrogenated block copolymer, the polysalicylate acetate, and the phosphorous-containing flame retardant additive,
- wherein the hydrogenated block copolymer is a hydrogenated polystyrene-poly(ethylene-butylene)-polystyrene block copolymer having a weight average molecular weight of 100,000 to 150,000, and
- wherein the phosphorous-containing flame retardant additive is bisphenol-A bis(diphenyl phosphate).
