Thermal silica film and thermal conductivity Guizhi difference

The coefficient of thermal conductivity: thermal silica film and heat conductive silicone grease thermal conductivity, are 1.9-3.0w / m.k and 0.8-3.8w / M.K.

The insulating heat conductive silicone grease: due to the addition of metal powder insulation, thermal    silica film good insulation properties . 1mm thickness electrical insulation index in the above 4000 volts.

The morphology: thermal conductivity Guizhi condensate paste, thermal silica film for sheet material.

Conclusion: using thermal grease need uniform (such as when the large size more inconvenience applicator ), easy and smudgy peripheral device caused short circuits and the scratching of electronic components; thermal conductivity of silica gel sheet can be arbitrarily cut, pull off protective film is directly stuck with, tolerance is small, clean, saving labor cost.

The thickness of filling gaps: as conductive materials, thermal grease is restricted, thermal silica film thickness ranging from 0.3-10mm, wide range of application.

The effect of heat conduction: the same thermal conductivity thermal conductivity Guizhi than thermal silica film is better, because the small thermal resistance thermal grease. Therefore, to achieve the same effect of heat conduction, thermal conductivity of silica gel plate thermal conductivity coefficient must be much higher than the thermal conductivity Guizhi high.

The new convenient installation, and the heat conductive silicone grease and again not easy applicator.

Order price: the thermal grease has been in common use, the price is low. Thermal conductivity of silica gel plate used in notebook computers, LED lighting and other small precision electronic products, the price is a bit high.

Below is the thermal conductivity of silica films with thermal conductivity Guizhi contrast:
