Are thermal grease and thermal silicone the same product? What is the main difference between the two?

2022-09-01

In thermal interface materials, both thermally conductive silicone grease and thermally conductive silicone can play a role in thermal conductivity. However, they are not the same product and should not be confused. Thermally conductive silicone has adhesive properties and is cured at room temperature. The thermal grease will not be cured and has no adhesiveness, so it cannot be used in combination. The difference between these two products is obvious, let's take a look together.


Different thermal conductivity

The thermal conductivity of thermally conductive silicone grease is between 0.3 and 1.0, and the thermal conductivity of thermally conductive silicone is between 0.6 and 1.5, and the applicable fields are different.

Different insulation properties

The insulation performance of thermal grease is very general, and metal powder is added in the production process, which limits the performance of insulation performance to a certain extent. The thermally conductive silica gel has good insulation properties and is more suitable for industries that require high insulation properties. Cooperate with powerful suppliers and feel more assured, such as TENSAN, which focuses on thermal grease research and provides customized thermal grease application solutions. , instruments, power supplies, high-speed rail, and other industries.

Different thermal conductivity

The thermal resistance of thermally conductive silicone grease is very small, which is much better than that of similar thermally conductive silicone sheets. The thermal conductivity of thermally conductive silicone is stronger, which is slightly better than that of thermally conductive silicone grease.

Different curing conditions

Thermal grease does not have any adhesive properties and will never cure. The thermal conductive silicone is different, has a certain adhesiveness, and can be cured at room temperature.

Different operating temperatures

The high-temperature resistance of thermal grease is very general and can only be used in an environment below 200 degrees. The thermal conductive silicone can work in an environment of 250 degrees, and it can also work in an environment of minus 50 degrees.

Different applications

Thermal grease is suitable for filling between the heat sink and the CPU. Thermal silica gel is suitable for industries related to electronic components and plays a role in sealing and potting.

 

In addition, the price of thermal grease and thermal silicone is different. The former is sold by the bottle, tens of yuan a bottle. The latter is sold in kilograms, and the price is not cheap.
