Keratherm FTC
Heat conducting films manufactured by a special process with copper (electrolyte) on one side. The beneficial properties of the heat-conducting film and copper create entirely new application possibilities, for example, active EMC protection or as system carriers of electronic switches.
The following copper tape/copper layer thicknesses are available:
17µm, 25µm, 37µm, 50µm, 75µm and 101µm
Elastomer thicknesses available up to 350µm.

Keratherm Copper as a system carrier of electronic circuits
On these system carriers, power densities of 5-10W/cm² can be realized. In this case, the heat conductive silicone film carries the electrical conducting circuit paths in copper etching technique. The second conducting path layer, for example in resistors, capacitors or coils, can be produced by applying polymer paste pressure.
In contrast to conventional circuit board technology, this method allows efficient production from a roll. The outstanding flexibility of the film permits the formation of interfaces and cable harnesses.
These system carriers for electronic switches represent state-of-the-art design from an economical and ecological perspective.
