    摘要: Polymer compositions are provided, and articles made therefrom. The polymer compositions comprise from 25 to 50 wt. % of a thermoplastic polymer; from 10 to 45 wt. % of a thermally conductive filler; from 15 to 30 wt. % of an electrically conductive carbon fiber; and less than 5 wt. % additives. The polymer composition is substantially free of glass fibers. The polymer compositions described herein surprisingly exhibit significantly improved thermal conductivity relative to analogous polymer compositions in which the carbon fiber is replaced by glass fiber. Further, even though carbon fiber has a significantly higher electrical conductivity relative to glass fiber, the polymer compositions exhibit no appreciable loss of volume resistivity relative to analogous polymer compositions in which carbon fiber is replaced by glass fiber.
