Abstract

Alpha alumina platelets are used as thermally conductive, electrically insulating filler in thermally conductive, electrically insulating elastomers. The platelets provide improved thermal conductivity in comparison to conventional alumina fillers. The platelets preferably average less than one micron thickness with an average aspect ratio of at least about 5:1.
