Thermal Management

In response to new heat-management challenges arising from the higher frequencies, power, and miniaturization of components, Momentive scientists have developed and continue to enhance an extensive portfolio of thermal management materials.

The excellent thermal conductivity and consistent, long-term heat transfer performance typically help enable devices to operate more efficiently and reliably. Our products, which include

Grease Compounds

Momentive's thermally conductive SilCool grease compounds offer excellent thermal conductivity, as well as excellent stability, penetration, temperature resistance, and low bleed. These properties enable SilCool grease compounds to draw heat away from devices, contributing to improved reliability and operational efficiency of electronic components.


Momentive Performance Materials family of SilCool thermally conductive adhesives can help deliver thin bond lines that contribute to low thermal resistance, and provide excellent adhesion and reliability. This series of heat-cured adhesives excel in thermal interface applications that demand good structural adhesion.

Encapsulants & Pottings

Momentive Performance Materials provides leading-edge silicone technologies to help meet performance and productivity challenges in a wide range of automotive and electronic applications. Momentive’s dielectric potting and encapsulation materials offer outstanding protection to electronic components from dust, moisture, fluids and harmful environmental contaminants.

Liquid Dispensed Thermal Pads

Momentive’s thermally conductive silicone gap fillers are dispensed to fill air gaps and voids in electronic components. They work with heat sinks or metal cases to dissipate heat from critical electronic parts. These non-adhesive curing silicones form a soft, stress-absorbing interface and fill uneven areas to improve cooling. Momentive’s Thermal Gap Fillers can also be applied to flat or high-profile 3-dimensional surfaces as a cure-in-place thermal pad or as a pump-out resistant alternative to greases.

High Thermal Gap Fillers

Faster processing speeds, more stringent performance requirements, and miniaturization in many electronic applications are some of the factors driving demand for new solutions to help meet thermal management challenges. Momentive’s SilCool* ultra-high thermally conductive gap fillers are liquid dispensed silicone materials available in thermal conductivities up to 10 W/m.K. These high thermal conductivities can help solve heat dissipation challenges and provide designers of electronic components with greater design flexibility to achieve performance expectations.
