Thermal Interface Material (TIM) for heat transfer
Thermal interface material, Gap fillers and thermal pads
Thermal interface material makes complete heat transfer between the heat sources (component, CPU, GPU, etc.) and the heat sinks (or chassis) by replacing the air in the gaps between the assemblies. Without these thermal interface materials, heat transfer is very quickly limited and the component risks overheating or even destruction.
Compelma is the French representative of Fujipoly, a Japanese manufacturer of high quality thermal interfaces. We work with this manufacturer for the quality and performance of its products. We then cut the thermal interface material to size to deliver turnkey gap filler pads.

Thermal interface materials, thermal pads or gaps are a single name for these thermal interface materials.
The levels of performance, hardness, thickness and quality vary enormously on the market. That’s why we work with you to offer the most suitable materials to meet your specifications and to last the lifetime of your project.

The thermal interface material avoid the layers of air (thermal insulation) between the components (CPU, GPU, processors) and the heat sinks.
The performance of thermal interface material (TIM) depends on the particle load of the silicone.
Compelma is Fujipoly’s European representative. For more information, please visit the website of our partner and expert Fujipoly on its SARCON® product range.
The interfaces are cut according to your drawings and packaged in sheets or reels according to their dimensions.
Our range comprises three main families: silicone-based, silicone-free and graphite.
-
Very flexible silicone base with thermal conductivity ≤17W/m.K These interfaces are made from a polymer matrix filled with thermally conductive particles. They conform perfectly to the geometries of a board’s components.
-
Silicone-free with a thermal conductivity ≤3W/m.K These interfaces are similar in functionality to silicone interfaces, but present no risk of outgassing or bleeding of silicone oil in sensitive environments (hard disks, optical components, etc.).
-
Graphite base with thermal conductivity ≤1500 W/m.K in the X,Y plane These thermal interfaces are available in natural or synthetic versions. These interfaces are suitable for thin thicknesses (a few tenths of a millimetre maximum). They can be laminated to metal parts (copper or aluminium) to increase the overall thermal performance.
