Introduction: with silica gel as the base material, adding various auxiliary materials such as metal oxides, a kind of heat-conducting medium material is synthesized through special process. In the industry, it is also known as heat-conducting silica gel pad, heat-conducting silicon film, soft heat-conducting pad, heat-conducting silica gel gasket, etc. it is specially designed for the design and production of heat transfer through the gap, which can fill the gap and open the gap between the heating part and the heat dissipation part The heat channel can effectively improve the heat transfer efficiency, at the same time, it also plays the role of insulation, shock absorption, sealing, etc., which can meet the design requirements of miniaturization and ultra-thin equipment. It is a kind of excellent thermal conductive filling material with high processability and usability, and wide application range of thickness.
