Silicone Thermally Conductive Encapsulants
DOW Silicones (formerly Dow Corning) delivers a wide variety of silicone-based polymers for diverse solutions in electric, electronic and energy applications. With increased miniaturisation of systems and increased circuit density, today’s electronics generate a large amount of heat. If the heat is not carried off and dissipated, the operational lifetime and reliability of the electronics can be reduced. This is a problem that needs to be addressed for everything from individual devices to electronic modules and systems.
We are offering a wide variety of DOWSIL™ and SYLGARD™ thermally conductive materials to meet the needs of different applications. These materials include curing adhesives, encapsulants and gels, non-curing compounds, and dispensable thermal pads. They can be used in many device configurations and perform well in accommodating high tolerances between surfaces.
As a class of materials, silicones maintain consistently high physical, electrical and optical performance at high temperatures. Available in a broad range of viscosities, cure chemistries and delivery formats, our products can help expand design and manufacturing latitudes.
DOWSIL™ and SYLGARD™ thermally conductive encapsulants are used as potting materials for high voltage transformers and sensors, assembly of heat sinks and fillers between heat sources.
