Classification: CPC C | IPC C

Claim 0:
1. A thermoplastic composition comprising:
(a) about 30 wt % to about 60 wt % of a resin component comprising polyphenylene ether (PPE) and polystyrene (PS), wherein the PS does not comprise a rubber reinforcement;
(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 comprising at least a partially hydrogenated hydrocarbon resin; and
(d) an elastomer component comprising from 2.5 wt % to 5 wt % rubber content in the composition excluding the filler component,
wherein 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),
wherein components (c) and (d) are distinct components, and
wherein the composition has a tensile strength retention, a flexural strength retention, or a notched Izod impact strength (NII) retention of at least 75% after heat ageing at 150° C. for 1000 hours, wherein tensile strength is determined at a speed of 5 mm/min in accordance with ISO527, flexural strength is determined at a speed of 2 mm/min in accordance with ISO178, and NII is determined at room temperature in accordance with ISO180.
