Thermal interface materials


As you design your devices to be faster, smaller and more powerful, you need to protect their high powered electrical components from heat, which can lead to degraded performance and damage.

The range of silicone-based, thermally conductive interface tapes are designed to move heat more efficiently through the material, constantly cooling the component. You get maximum thermal management and excellent long-term performance under extended high temperature conditions.

We offer you thermal interface materials from Bergquist resp. Henkel-Adhesives, as customized die-cut parts. For applications in electronic industry the following materials have been proven:
