According to the material of the computer, it is recommended to use thermal pad.

Because it has certain flexibility, compressibility and natural viscosity on the surface, it can fill the gap and complete the transfer between the heating part and the heat dissipation part. At the same time, it also plays the role of insulation and shock absorption, and penetrates the computer shell through heat transfer.

Now in the electronic market, thermal conductive graphite sheet and thermal conductive silicone pad belong to heat conduction medium, but there are still differences between them. What is the difference between thermal graphite sheet and thermal silicone pad?


The thermal silicone pad is generally based on silica gel and added with metal oxide and other auxiliary materials. It is a kind of thermal conductive medium material synthesized by special method. Thermal conductive silica pad is designed to transfer heat through the gap. It can fill the gap and complete the heat transfer between the heating part and the heat dissipation part. At the same time, it also plays the role of insulation, shock absorption and sealing.


The thermal pad and graphite sheet are different regardless of their application range


1. Thermal graphite sheet is a kind of electronic thermal conductive material which is made of polyimide film or graphite powder by high-temperature calendering. It can be made into a certain viscosity and insulation property of electronic heat-conducting material by laminating.


2. The heat conduction mode of the graphite sheet is that the temperature of the heat source is diffused by the high thermal conductivity of the graphite level, and the heat conduction is carried out in the vertical direction at the same time.


3. Because of its ultra-thin thickness, graphite sheet plays an important role in heat conduction and heat dissipation of high-power and high heat electronic products such as smart phones, tablet computers, LED lighting.


Thermal graphite sheet and thermal silicone pad are different in heat conduction mode, process characteristics and application range, so we need to understand their basic characteristics in use. As a high-tech enterprise integrating R & D, production and sales, Suzhou Dasen Electronics Material Co., Ltd. produces various thermal interface materials, such as graphite sheet, thermal silicone pad, thermal gel and thermal tape.
