Abstract: The present invention provides for a power transfer belt that is manufactured of a highly thermally conductive polymer composition, in contrast to the typical rubber material used to fabricate the belts of the prior art. The new and unique belt of the present invention is manufactured of a thermally conductive polymer material that is easily injection moldable into any desired shape and configuration. Further, the polymer composition is very thermally conductive, which assists in dissipating heat that is generated by the friction created during normal operation of the device. The new belt material and its construction allow heat to be conducted directly through the surface of the belt thus preventing heat buildup within the belt itself, thereby preserving and extending its life. Further, the present invention provides a novel method whereby a thermally conductive belt is manufactured through net shape molding.
