Abstract: A desirable balance of heat resistance and flame retardancy is exhibited by a composition that includes specific amounts of a poly(phenylene ether), a poly(phenylene ether)-polysiloxane block copolymer reaction product, a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, and an organophosphate flame retardant. The composition minimizes or excludes reinforcing fillers, certain adhesion promoters, and addition polymers that include repeat units derived from a glycidyl ester of an α,β-ethylenically unsaturated acid.

Abstract: A thermoplastic composition includes: (a) about 30 wt % to about 60 wt % of a resin component including polyphenylene ether (PPE) and polystyrene (PS); (b) from about 35 wt % to about 65 wt % of a filler component; (c) from about 1 wt % to about 5 wt % of a flow promoter including at least a partially hydrogenated hydrocarbon resin; and (d) an elastomer component including from 2.5 wt % to 5 wt % rubber content in the composition excluding the filler component. The combined weight percent value of all components does not exceed 100 wt %, and all weight percent values are based on the total weight of the composition except as indicated in (d).
