The difference between thermal conductive silicone grease and thermal conductive silicone

The difference between thermal grease and thermal silicone pad

Thermally conductive silicone pad is a kind of thermally conductive medium, which is generally used to reduce the contact thermal resistance between the surface of the heat source and the contact surface of the heat sink. Therefore, in the industry, it is generally called a heat-conducting silicone pad, or a soft heat-dissipating pad.

Because of its characteristics of flexibility, excellent insulation, stretchability and surface natural stickiness, it is specially produced for heat transfer through the gap, so it can complete the heat transfer between the heating part and the heat dissipation part, and can also provide insulation and damping.

With the continuous development of electronic devices, functions can now be integrated into smaller components. Typically, this results in size and space limitations for electronic devices. The compressibility of the thermally conductive silicone pad can well meet this requirement, but because the thermally conductive silicone pad is too thin, it is easy to tear, so it is necessary to add glass fiber to increase its tensile strength.

Thermal grease is generally called thermal paste. Thermally conductive silicone grease is generally a silicone grease-like compound with thermal conductivity and heat dissipation properties made of silicone as the main raw material and added with heat-resistant and thermally conductive materials. This composite material has excellent electrical insulation and thermal conductivity. The material hardly solidifies and generally remains greased for a long time at temperatures from -50°C to +230°C .

Thermally conductive silicone grease also has a series of characteristics such as low freeness, water resistance, ozone resistance, and weather resistance. Now this material has been widely used in the heat dissipation of various electronic products.
