Compared with thermal paste, what are the advantages of thermal gel?

So what kind of gap filling thermal conductive material is thermal gel? What are its advantages to make people think that it is a thermal conductive material capable of replacing thermal conductive paste?

Thermally conductive gel is a kind of gel that uses silicone resin as the matrix, adds thermally conductive fillers and bonding materials in a certain proportion, and is processed by a special process. In the industry, it is also known as thermal conductive silica gel mud and thermal conductive mud. It has high thermal conductivity, low interface thermal resistance and good thixotropy. It has become an ideal material for applications with large gap tolerances. It is filled between the electronic components that need to be cooled and the radiator/shell to make them in close contact. Reduce the thermal resistance, quickly and effectively reduce the temperature of the electronic components, thereby prolonging the service life of the electronic components and improving their reliability. The common use method is manual coating or dispensing equipment.


Thermal gel has a long working life. Anyone who has used thermal paste knows that after a period of use, the thermal paste needs to be cleaned up and then reapplied. The thermal gel has a long working life. According to big data statistics The general working time of the gel can reach 5-10 years, and the qualified thermal conductive gel will not crack or solidify during long-term work.

The thermal gel is very convenient to use. The thermal gel is also called the thermally conductive silicone gasket. It is a soft paste like silicone rubber. After filling the gap, it is like a gasket. It can be customized according to the shape of the plane. After the error, only need to remove the glue.

Thermal gel can be used in an automated dispenser. Now the industry is pursuing automated production to improve efficiency. In the past, the thermal paste needed to be stirred when used, and the thermal gel was shipped in a sealed package, and the automatic dispenser was installed directly when used. However, it is very convenient to use and install, and can adapt to the high-tempo industrial automation production needs.

Thermally conductive gel is a very convenient and efficient thermally conductive material. Although its price is higher than that of thermally conductive paste, its advantages make thermally conductive gel still a thermally conductive material trusted by enterprises.
