Thermal Management

Chomerics thermal interface materials include phase-change materials, thermally conductive adhesive tapes, insulator pads, flat sheet and molded gap fillers, cure-in-place thermal cpmpounds, and copper and ceramic heat spreaders.

Chomerics has recently introduced its latest thermal interface material. Fully-cured, dispensable GEL30 effectively cools complex automotive electronics providing for long-term reliability of components. It decreases storage and handling issues associated with traditional thermal interface materials, and provides for automation and increased design and manufacturing flexibility for electronic control unit (ECU) manufacturers.
