A thermally conductive and electromagnetic interference and radio frequency reflective polymer composition and a method for creating the same is disclosed. Thermally conductive filler material is coated with a thermally conductive and electromagnetic interference and radio frequency reflective coating material and mixed with a base polymer matrix. The mixture is molded into the desired shape. The electromagnetic interference and radio frequency reflective coating material prevents the absorption and transfer of EMI and RF waves through the filler material thus resulting in an EMI and RF reflective composition.
