Abstract: A reflective article includes an injection molded thermoplastic substrate, and a reflective metal layer disposed on a surface of the thermoplastic substrate. The injection molded thermoplastic substrate is prepared from a pre-blended composition including specific amounts of two poly(phenylene ether)s having different intrinsic viscosities, an atactic polystyrene, and, optionally, a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene. The reflective article is lighter and less costly than comparable reflective articles based on heat-resistant polycarbonates. Also described are a melt-blended composition derived from the pre-blended composition, and an injection-molded article prepared from the melt-blended composition.

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).
