China has never left behind in the research and use of thermally conductive materials, and has remained at the international cutting-edge level. Especially relying on the development needs of China's aerospace technology and high-end electronics industry, the development of thermally conductive graphite sheets has been a surprise. At present, 80% of domestic high-end electronic applications are preferred to use thermally conductive graphite sheets as thermally conductive insulating materials, because its superior thermal conductivity is the advantage of any electronic product in terms of performance and service life.

In some low-end electronic products, materials such as metal aluminum and copper were originally used as thermal conductive medium materials. Later, some silicone grease materials and silicone materials with aluminum and copper metal powders as fillers were developed. The performance has indeed been greatly improved, but due to their physical characteristics such as high density, insufficient thermal conductivity, and high thermal expansion coefficient, they can meet the requirements of China's aerospace technology and high-end electronics industry for thermal and thermal performance. In the study of carbon elements, it was found that natural graphite is exquisitely processed, and graphitized films can be obtained at high temperatures and pressures. This is the origin of thermally conductive graphite sheets.

Although the main body of the thermally conductive graphite sheet is composed of carbon elements, it has the electrical and thermal conductivity properties of metal materials, and also possesses the plasticity peculiar to this organic plastic. It is important that its thermal conductivity is far beyond that of copper and aluminum. Now the new technology has completed the coating of metal materials on the surface of graphite materials based on the preparation and processing of thermally conductive graphite materials. Of course, such precision materials are mainly used in aerospace technology. Then you have to ask, the performance of thermally conductive graphite sheet is so excellent, then all the thermally conductive materials have to be replaced by it? This statement can be established without considering the cost. In terms of the current output and production cost of thermally conductive graphite sheets, it can only be used by some high-end electronics markets. What I want to say is that with the technological innovation, the mass production technology of thermally conductive graphite sheets has become more mature and the cost has been controlled. Thermally conductive graphite sheets will definitely take the lead in thermally conductive materials, and can be used in high-end and low-end electronics See it.
