Abstract: Polymer resin compositions include a thermally conductive filler and one or more of a white pigment or an optical brightening agent. In a particular aspect a polymer composition includes: from about 20 wt. % to about 80 wt. % of a polymer base resin; from about 1 wt. % to about 70 wt. % of a thermally conductive filler; from about 0.1 wt. % to about 50 wt. % of a white pigment; and from about 0.001 wt. % to about 10 wt. % of an optical brightening agent. In certain aspects the polymer composition exhibits a through plane thermal conductivity of at least about 0.3 W/mK and a reflectivity of at least about 80%. In further aspects the polymer composition exhibits a through plane thermal conductivity of at least about 0.3 W/mK and a reflectivity of at least about 90%.
