    Abstract: Thermally conductive materials comprising a non-polar elastomer, a polar elastomer, and a thermally conductive filler. The polar elastomer and non-polar elastomer are sufficiently immiscible to form a polar elastomer phase and a non-polar elastomer phase. The thermally conductive filler is concentrated in an amount of at least 60 volume percent of the total filler amount in either the non-polar elastomer phase or the polar elastomer phase. The thermally conductive material has a tensile modulus less than 200 MPa. Such thermally conductive materials can be employed in a variety of articles of manufacture as thermal interface materials.
