Thermally conductive silicone sheets have become one of the important thermal conductive interface materials due to their excellent softness and elasticity, interface adhesion, low thermal resistance and high thermal conductivity. Thermally conductive silicone sheets are a kind of thermal conductive medium material synthesized by a special process with silicone as the base material and various auxiliary materials such as metal oxides.
