More power and light weight. In the past, these two characteristics in electronics were mutually exclusive. Now, micro-electronics are just that, and in addition, need thermal management components to further complement these objectives.

SARCON® is an advanced silicone rubber with high thermal conductivity and superior flame-retardancy. By combining the inherent silicone rubber properties of heat resistance, electrical insulation and long-term aging into one compound, this universally applicable material can be made in an unlimited number of thermal management configurations.

SARCON® Thermal Gap Filler Products

Thermal Gap Filler Pads are highly conformable and high heat conducting gel materials in a versatile sheet form.

Thin Film Profiles

The following table contains links to all Thin Film Profile products. Select a part to view details

Die-Cut Gaskets

Standard die-cut parts. Effective also as a mounting cushion to prevent deformation. Customs available in unlimited sizes and shapes.

Sleeves

Tube shapes available in three thicknesses. TR, HR or Y-A formulations. The flexible structures conform to most applications.

Cases

Box-shaped caps for transistors. High thermal dissipation rate. Open on one end; installs by just slipping over the desired components.
