Abstract
In order to provide a thermally conductive polymer-based resin that may be molded using a range of thermoplastic manufacturing techniques, a composition includes a thermoplastic polymer and/or elastomer, a polymer fiber, a binding agent, and a thermally conductive filler. The composition includes from 40 to 80 volume percentage of a thermoplastic polymer and/or a thermoplastic elastomer, from 5 to 30 volume percentage of a polymer fiber, from 0.1 to 20 volume percentage of a binding agent, and from 10 to 40 volume percentage of a thermally conductive filler. The polymer fibers and thermally conductive fillers are combined to create a hybrid thermally conductive particle for better feeding in standard plastic processing methods. The polymer fiber has an aspect ratio greater than 10. The filler has a thermal conductivity greater than or equal to 10 W/m-K. The composition is characterized by a thermal conductivity of at least 1 W/m-K.
