How to choose thermal conductive silicone film?

There are many thermal conductive silicone films on the market, so what aspects should we pay attention to when choosing them? Thermal conductive silicone film is specially designed for the use of cracks to transfer heat. It can fill the cracks and complete the heat transfer between the heating and heat dissipation parts. It also plays the role of insulation, shock absorption, sealing and so on. It can meet the design requirements of miniaturization and ultra-thin equipment. It is a very technological and usable material with wide thickness and application range. It is an excellent thermal conductive filling material. 。



The following points should be paid attention to when choosing thermal conductive silicone film:

1. Thermal conductivity. The thermal conductivity is the physical parameter of the material itself, and can not be used as the only distinguishing condition between good and bad. In principle, the higher the thermal conductivity, the better. But the factors to be considered are hardness, area and price.



2. Viscous requirements. In principle, it is not recommended to use thermal conductive silicone film backing instead of other fixtures, because the thermal conductivity of the double-sided adhesive is not high, the overall thermal conductivity of the thermal conductive silicone film behind the backing adhesive will be reduced, and the effect behind the double-sided adhesive will be worse. In addition: thermal conductive silicone film due to raw materials, there will be a weak natural viscosity, but this can not be used as a fixed. Must be strong viscous thermal conductive material, you can choose our company's thermal conductive double-sided adhesive.



3. Requirements for glass fibers. Due to the material limitation of silica gel itself, in principle, the thickness is not less than 0.5mm, and the thermal conductive silica film below 0.5mm will increase glass fibre by default. The thermal conductivity of glass fibre itself is general. Increasing the thermal conductivity of glass fibre mainly plays a supporting role in the thermal conductive silicone film to prevent too thin to be torn and difficult to install.



When choosing thermal conductive silicone film, we should only pay attention to the above three aspects.
