Silicone Thermally Conductive Gels

Product description

DOW Silicones (formerly Dow Corning) delivers a wide variety of silicone-based polymers for diverse solutions in electric, electronic and energy applications.

DOWSIL™ and SYLGARD™ silicone gels are a special class of encapsulants that cure to an extremely soft material. Gels cure in place to form cushioning, self-healing, resilient materials. Cured silicone gels retain much of the stress relief and self-healing qualities of a liquid while providing the dimensional stability of an elastomer. Typically, gels are used to protect circuits from the harmful effects of moisture and other contaminants and provide electrical insulation for high voltages. Another key characteristic of most gels is a naturally tacky surface after cure. This natural adhesion allows gels to gain physical adhesion to most common surfaces without the need for primers. The tacky nature also results in the unique ability to re-heal if the cured gel has been torn or cut. The ability to re-heal permits the use of test probes directly through the gel for circuit testing.

DOWSIL™ and SYLGARD™ thermally conductive gels are used as filling material, potting in housings and raw material for the production of gel sheets.
