They are commonly used in notebook computers or other electronic devices as contact media for heat sinks and packages. The role is to reduce the contact thermal resistance, enhance the thermal conductivity between the package and the heat sink, and also play the role of insulation, vibration damping, sealing, etc. It can meet the requirements of miniaturization and ultra-thin design of equipment, which is a great process and usability, and a wide range of thickness, an excellent thermal conductivity filling material.

Thermally conductive silicone grease is used in liquid form to disperse heat from electronic heating parts and improve the efficiency of electronic parts. It is a thermally conductive silicone grease-like compound made of silicone as the main raw material and liquid form as the main storage medium, with the addition of materials with excellent heat resistance and thermal conductivity, and is now widely used as a material for heat conduction of electronic original devices such as CUP, transistors and electronic tubes. The following is a comparison of thermally conductive silicone film and thermally conductive silicone grease, which can be selected according to your own needs and hardware conditions when purchasing.

1, thermal conductivity: In the short term, the thermal conductivity of thermal grease is better than that of thermal conductive silicone film, because the thermal resistance of thermal conductive silicone film is large, and the thermal resistance of thermal conductive silicone grease is smaller.

2, thermal conductivity: thermal conductivity of silicone grease is 1.0~5.0W/Mk, thermal conductivity of silicone film is 0.8~8.0W. (Of course, the higher the thermal conductivity, the better it is)

3, construction: the construction of thermal conductive silicone grease is more troublesome, difficult to apply evenly, easy to dirty the surrounding devices. The thermal conductive silicone film has been cut according to the size in advance, just tear off the protective film, align the paste surface and paste it on, simple and convenient.

4, heavy industry: thermal conductive silicone grease can not be heavy after disassembly, thermal conductive silicone film can be repeatedly installed and used.

5, insulation: thermal conductive silicone film has high insulation, 1mm thickness voltage resistance up to 15KV; thermal conductive silicone grease does not have insulation performance.

6, service life: thermal conductive silicone film has stable thermal conductivity, and its service life can be more than 10 years; thermal conductive silicone grease is prone to dry solid, chalking, cracking and other phenomena due to long time use, and its service life is generally about two years.

7、Thickness: The thickness of thermal conductive silicone grease is generally 50~80um; while the thickness of thermal conductive silicone film can be from 0.3~5.0mm, as a gap-filling thermal conductive material, it can be used more widely.

8, shock absorption: thermal conductive silicone film because of its softness, can be used in high compressibility, has the effect of shock absorption, can be used as a vibration absorber, and thermal conductive silicone grease because it is paste, can not play the role of shock absorption.

Of course, the price of thermal conductive silicone film will be much more expensive than thermal conductive silicone grease.
