Are thermal grease and thermal silicone the same? Are there any differences?


Thermal grease has a good heat dissipation effect when used in electrical appliances, ensuring the safety and service life of the appliances. Thermal silicone also has a good heat dissipation effect, and its main application areas include electrical appliances, automobiles and other parts. So are the two the same? Can they be used interchangeably?

Although both thermal grease and thermal silicone have heat conduction effects, their raw materials, usage methods and application areas are different.

Raw material differences

The main raw material of thermal grease is organic silicone, and then some heat-resistant materials are added. This material eventually presents a paste state, and will not be cured before and after temperature resistance. Thermal silicone is a high-end thermal conductive compound.

Features are very different

Thermal grease is in a paste state, which can play a good thermal conductivity role after use. It is a thermally conductive and non-conductive material. It can also resist high and low temperature changes and has high stability during use. Thermal silicone is a single-component adhesive. Once it comes into contact with water vapor in the air, it will undergo a curing reaction. After curing, it has various properties such as thermal conductivity, moisture resistance, corona resistance, and leakage resistance.

Different uses

Thermal grease can only be used in the middle of the electrical heating element and the heat dissipation facilities to exert its performance. It has no effect if used in other positions. Thermal conductive silicone can be used in various electronic products and electrical appliances, and can be used to bond and fix electrical components.

Different usage methods

Thermal conductive silicone grease can be directly applied to the substrate to be applied, and the next construction can be carried out without waiting for curing, because thermal conductive silicone grease will not undergo a curing reaction. Thermal conductive silicone needs to be thoroughly cured after construction before the next construction can be carried out. The glue that has not been thoroughly cured has no bonding and heat conduction effects.

Thermal conductive silicone grease is unique. It is a material that will not corrode and has no effect on human health when used in electrical components. At present, there are many brands of this material. In order to buy high-quality products, it must be carefully selected. You can cooperate with brand companies, such as TENSAN, which focuses on the research of thermal conductive silicone grease and provides customized thermal conductive silicone grease application solutions. It has a wide range of uses and can be applied to new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
