About Grease

About Lubricants

Bond heat sinks to surfaces, eliminating air gaps for maximum heat transfer. These compounds are commonly used with transistors, diodes, rectifiers, and transformers. Product regulations restrict sales to the listed jurisdictions/areas.

Zinc-oxide compounds create a more secure bond than silicone compounds.

Non-Bonding Heat Transfer Compounds

Heat Transfer Compound

Also known as thermal paste, these boron-nitride compounds increase heat transfer between parts while preventing them from sticking. Unlike antiseize compounds, they don't conduct electricity, so you won't risk shorting out sensitive electronics. They're often used on thermocouple probes to improve accuracy. You can also use them in 3D printer heating blocks and other high-temperature areas to keep parts from fusing together.

Heat-Transfer Foil

Made of indium, this foil is more thermally conductive than thermal interface materials (TIMs) made of plastic. By efficiently pulling heat away from components that produce heat, such as CPUs, this foil lets you use smaller forced cooling systems to extend battery life. It’s also softer and more ductile than paste and putty, covering surfaces better to minimize airflow gaps and increase heat flow. Unlike paste and grease, this foil won’t leach out from between surfaces over time, nor will it dry out and lose effectiveness. It’s clean, easy to install and reposition, and requires no surface preparation. Foil is corrosion resistant and doesn’t need special storage.

Foil with 48% tin has greater tensile and shear strength than foil without tin, but is less thermally and electrically conductive.

Conductive Liquid Gallium

Often used as a safe alternative to mercury in thermometers, thermostats, and switches, these gallium alloys are also good for transferring heat and electricity in soft electronics that must bend and flex. With a low melting point, they’re a liquid at room temperature. These alloys wet (stick to) both metallic and nonmetallic surfaces, and can even be used as a high-temperature lubricant for bearings. They will, however, dissolve aluminum at room temperatures and many other metals at higher temperatures. They’re also known as Galinstan.

Gallium alloys with 66.5% gallium have a lower melting temperature than those with 75.5% gallium. They are not, however, as good for transferring heat.

Gallium alloys with 75.5% gallium are better than those with 66.5% gallium for transferring heat. They also have a higher melting temperature.

Electrically and Thermally Conductive Grease

A high silver content gives this grease excellent conductivity for applications where electricity and heat transfer are required. It is suitable for ESD (electrostatic discharge) and EMI (electromagnetic interference) shielding applications.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter.

Electrical resistivity is a measure of how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.

Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.

Grease lubricates most efficiently within the listed temperature range. Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.
