Thermally conductive silicone pads are a polymer composite material with silicone rubber as the base material and thermally conductive fillers added. Its main function is to fill the gap between electronic components and radiators, improve the efficiency of heat conduction, and ensure the stable operation of electronic equipment. The core of thermally conductive silicone pads lies in the selection and ratio of its materials, which not only determines its thermal conductivity, but also affects its softness, insulation and durability.
