Thermal Grease

The constantly increasing technical demands on electrical and electronic assemblies lead to major challenges in the area of thermal management. Due to the miniaturization of components and the higher performance of devices, component temperatures would increase significantly without countermeasures, which can lead to the failure of the entire assembly. In order to increase the longevity of electronic components, heat must therefore be conducted from the heat source (electronics) to the heat sink (e.g. heat sink). Thermally conductive and electrically insulating intermediate layer materials, so-called Thermal Interface Materials (TIMs), are used for this purpose. KERAFOL® has developed effective, uncomplicated and cost-effective solutions in this area with the KERATHERM® and KERAMOLD® product ranges. Thermal Grease is a product group that is also well-known in the consumer sector.

What is Thermal Grease?

an explanation

Thermal Grease are thermally conductive and non-crosslinking 1-component materials, e.g. based on silicone. Due to their special filling, thermal greases can be compressed to very thin layer thicknesses of < 25 µm. Due to this special plasticity and the thin layer thickness, an incomparably low thermal resistance can be achieved. This contributes significantly to the enormous cooling capacity of electronic components.
Kerafol has silicone-free alternatives for all sensitive components/applications where products containing silicone must not be used.

Delimitation

to other products

In contrast to gap filler liquids, thermal grease are non-crosslinking systems and therefore do not harden. Due to special fillers and the very thin layer thickness, thermal grease are not electrically insulating. The degree of filling and the density of greases are very high. The choice of fillers is always based on the need for easy dispensing. In terms of the gap to be bridged over a certain area, greases are a more cost-effective alternative to films, also because the material utilization is higher (e.g. no material is lost due to punching residues). This is offset by the investment costs for a dosing or screen printing system.
