Thermally Conductive Grease

What Is Thermal Conductive Grease?

Thermally conductive grease is a type of one-component thermal management material designed to manage and dissipate heat generated in increasingly powerful devices. 

Single component greases are thermally conductive compounds that connect a heat source to a thermal spreading device. These flexible, high-performance thermal conductive grease products are useful in many thermal settings, such as heat sinks and almost all electrical applications. They offer fantastic thermal management performance and application flexibility to suit a wide range of assemblies.

Thermal conductive greases offer low thermal impedance and resistance, which improves the overall thermal conductivity of a system to improve the performance and reliability of devices.

Why Use Henkel Thermally Conductive Grease?

For manufacturers with a preference for traditional thermally conductive grease compounds, Henkel offers several REACH/RoHS-compliant formulations that fit a wide range of applications. Used in high-performance applications where a small bondline thickness is essential for high thermal performance, our LOCTITE^® Bergquist^® brand thermally conductive greases offer immediate functionality upon application and fantastic thermal performance. 

Our greases are the ideal option for easily compensating for voids within assemblies. This makes them a perfect solution for use in devices that have issues with flatness or coplanarity.

Available in cartridges or bulk containers, Henkel’s thermal greases include high-performance, high-temperature reliability, thermal conductive silicone grease, silicone-free, and water-cleanable formulas.

The line of thermally conductive thermal interface compounds (TIC) offers a range of products designed to flow under assembly pressure to wet-out the thermal interface surfaces and produce very low thermal impedance. 

TIC products are suitable for many assemblies and components, offering improved thermal performance and reliability of assembly. They are often deployed in applications between a high-end computer processor and a heat sink, or other high-watt density applications.

Choosing a Thermal Grease Product

The thermally conductive grease compound portfolio is made up of a range of products with diverse thermal characteristics. These all dictate which product is the best option for your specific application and needs. When choosing your thermal grease compound, considerations will include:

• Required viscosity for flow needs in your application.
• The required level of thermal resistance for your heat-dissipating needs.
• Level of thermal conductivity required.
• The thermal performance, depending on the heat generated within a device.
• Size of the gap that must be filled within a device.
• The type of resin required for use.
