What are the main components of thermal conductive silicone?

The main components of thermal conductive silicone include base polymer, filler and catalyst.

1.Base polymer‌:Thermally conductive silicone usually uses methylvinyl polysiloxane or methylhydrogen polysiloxane as the base polymer, which has good elasticity and temperature resistance.

2.Filler‌:Commonly used fillers include alumina, aluminum hydroxide and boron nitride, which can improve the thermal conductivity of silicone.

3.Catalyst‌:Platinum catalyst is used to promote the curing reaction of silicone, usually using PT complex.

In addition, thermally conductive silicone may also contain some additives, such as alcohol retarders, to adjust the curing time and performance.

Thermally conductive silicone has excellent resistance to hot and cold alternation, aging resistance and electrical insulation performance, and can maintain performance in the temperature range of -60℃ to 280℃. It is widely used and suitable for the connection and heat dissipation needs between various electronic components and heat dissipation equipment.
