The difference between thermal conductive silicone grease and thermal conductive silicone pad

Thermal conductive silicone pad is a 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 thermal conductive silicone pad, or soft heat dissipation pad, and so on.

Because it has the characteristics of flexibility, excellent insulation, stretchability and natural viscosity on the surface, it is produced specifically for heat transfer through the gap, so it can complete the heat transfer between the heating part and the heat dissipation part, and it can also provide insulation. And shock absorption.

With the continuous development of electronic devices now, functions can now be integrated into smaller components. Generally, this will lead to limitations in the size and space of electronic devices. The compressibility of thermal conductive silicone pads can well meet this demand, but because of thermal The conductive silicone pad is too thin and easy to tear, so glass fiber needs to be added to increase its tensile strength.

Thermally conductive silicone grease is generally called thermally conductive paste. Thermally conductive silicone grease is generally made of silicone as the main raw material and added with heat-resistant and thermally conductive materials to make a silicone grease-like compound with thermal and heat dissipation properties. This composite has excellent electrical insulation and thermal conductivity. This material will almost never solidify, and generally can maintain the grease state for a long time at a temperature of -50°C to +230°C.

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