Thermally conductive plastics

Thermally conductive films, greases and compounds

Electronic components will often only function perfectly within a narrow temperature range.
Optimum cooling, using a heat sink, for example, requires equally optimum thermal coupling of widely different components to the cooling element. Thermally conductive films have developed into excellent, gap-filling materials with a high thermal conductivity value. In contrast to metal-based solutions, they also offer electrical insulation, making the heat sink design much simpler.
