Thermally conductive foils made of silicone achieve an excellent thermal transfer between electronic packages and heat sinks. Being based on silicone, a long-term stability is ensured. Their respective thermal conductivity depends on filling degrees of particular thermally conductive powders or compositions thereof, as well as on their respective geometry and own thermal conductivity. Together with the property both to comply with the contact surfaces and to be compressible under pressure, the total thermal resistance is minimized. At the same time a permanent electrical insulation is assured.

The product line is complemented by thermally conductive caps and tubes for an electrical all-around insulation.
