Keratherm Standard Films - MH&W Thermal Products

Kerafol LogoFlexible films consisting of a silicone elastomer filled with various thermally conductive ceramic materials. All film types are electrically insulating. For improved handling, the films are also available with fiberglass reinforcement. The standard films adapt to the component surface. Small irregularities can be evened out by using only minimal contact pressures. The good thermal properties of these films guarantee optimum heat transport to the heat sink and at the same time good electrical insulation properties. All Keratherm standard films are UL tested.
