Before the earliest thermal conductive silicone sheet was developed and formed, there was a certain contradiction between thermal conductivity and insulation. Generally, materials with good thermal conductivity are basically not insulated. For example, metal is a good thermal conductor, which is a good thermal conductive material, but it does not have insulation. Silica gel is a good electrical insulating material, but it does not have any thermal conductivity itself. Thermal silica gel sheet uses its physical inert characteristics, and has good insulation and thermal conductivity by adding different alumina, boron nitride, etc. High-quality thermally conductive powder, processed by special processes such as kneading, extrusion molding, high temperature, etc., is a high-quality thermally conductive material (thermally conductive silicone sheet) that can conduct heat and has insulating properties. The thermally conductive silicone sheet is generally soft and easy to use. The intermolecular size is packed tightly and tightly to achieve high density, which is conducive to the heat transfer between molecules during heat conduction. The thermally conductive silicone sheets developed and produced by our company are all made of high-precision powder fillers, which do not contain harmful substances such as lead and mercury. The thermal conductive silicone sheet is flat and smooth on both sides and soft in texture. It is specially produced for the design scheme of using gaps to transfer heat, and has strong filling ability.
