The highly thermally conductive White Group with their well balanced thermal and electrical or dielectrical behavior are created by filling a silicone elastomer base with aluminum oxide. An increase in mechanical strength can be achieved by fiberglass reinforcement. Both the unreinforced and reinforced film types can optionally be supplied with an adhesive coating. In general, however, the very good self-adhesion of the film will be sufficient for the mounting required.
