Abstract

In order to render an elastomeric material thermally conducting, large volume quantities of high thermal conductivity fillers are incorporated therein. In a paper en titled, Conductive Polymeric Compositions, Polymer Engineering and Science, Volume 17, December 1977, pages 842-847, there is a detailed discussion regarding the addition of conductive fillers to polymer materials to increase thermal conductivity. However, problems are encountered because the high volume loading of such fillers causes the elastomer to become weak; that is, the high volume loading causes low tensile strength, low percent elongation and low tear strength. Furthermore, the high volume loading of such fillers complicates the processing of the elastomeric material. The weakening effect has been visualized as being caused by a dewetting of the filler particles from the elastomer matrix. The material is hard to process because of insufficient dispersion of the filler particles within the elastomer matrix.
