Product description

CMC 15005 is a silicone film for thermal interconnection between e.g. MOSFETs or IGBTs and cooling surfaces. It combines excellent thermal conductivity with good electrical insulation, mechanical stability and easy handling. The silicone is resistant to ageing and its surface can adjust to minor irregularities to provide optimal thermal contact. silicone with ceramic fillers and fibre glass
