Material developers at Datwyler, a provider of system critical, high-performance polymer products, have been working to develop thermally conductive materials to support the thermal management of BEVs, including thermal interface materials (TIMs).
TIMs, by conducting the heat away from the source to the cooling systems, help to keep the optimal temperature of battery systems. The cooling or heating ability of these materials is directly linked to the thermal conductivity described as lambda and is expressed in W.mK.
There are various forms and types of TIMs, whether it is conventional “solid” rubber compounds, foams, resins, adhesives and others. Apart from others, these materials can be processed as form-in-place (foams, adhesives, resins, and generally thermo-setting materials) and in the form of stand-alone gaskets (rubber compounds).
