KERAMOLD - MH&W Thermal Products

Thermally conductive injection molding granulate

Besides the conventional Thermal Interface Material
solutions in forms of Tapes, Pads or Liquids, KERAFOL®
has also developed a thermally conductive injection
molding granulate (KERAMOLD®) based on a TPE
polymer (Thermoplastic Elastomer).

This new series of injection molding granulate makes it possible to
achieve a 3D heat transfer and a high level of electrical
insulation at the same time. In addition, electrical components can be completely covered with thermally conductive materials through the over molding process. This means that electronic components cannot only be cooled, but also protected from dust and mechanical influences, a real alternative to conventional potting materials due to the fast processing time.
