Which is better, thermal conductive gasket or thermal conductive silicone grease?
Thermal conductive gasket and thermal conductive silicone grease are both materials used for heat conduction and heat dissipation. In the current market, these two kinds of heat conduction materials have been applied. However, due to their different manufacturing processes and materials. There are also differences in the use of this heat conducting material. Which of the two materials is better? It‘s better to see the difference between the two before we can understand it.
Let me first know about this thermal conductive gasket. It is a soft material with good thermal conductivity. This composite material also has good insulation. This material is mainly made of boron nitride with high thermal conductivity and silicone polymer.
Let‘s talk about thermal conductive silicone grease, which is a thermal conductive material using silicone resin. It has good wettability, and is a good application for some uneven contact surfaces.
From the above, it can be seen that the thermal conductive gasket and thermal conductive silicone grease have their own unique features, and we can‘t say which is good or which is bad. Now let‘s take a look at the advantages and disadvantages of the two and make a further judgment.
In terms of insulation, the insulation of thermal conductive gasket is better than that of thermal conductive silicone grease. This is mainly due to the existence of metal in conductive silicone grease, and the natural insulation is worse. Secondly, when using, the silicone gasket is more convenient, because it can be cut according to the size needs. The thermal conductive silicone grease needs to be coated carefully. Otherwise, the components will be dirty and even short circuited.
In addition, in terms of service life, the thermal conductive gasket is solid, and the thermal conductive silicone grease is a solid liquid mixed material. Compared with silicone grease, the silicone oil is more volatile. Therefore, thermal conductive silicone grease is prone to aging after a long service life, and its service life should be shorter. Another is the thermal conductivity. At the same thermal conductivity, the thermal conductivity of thermal conductive gasket is worse than that of thermal conductive silicone grease. This is mainly because the thermal resistance of conductive silicone grease is small.
The characteristics of the two are that they have their own advantages. If you want to say which is better, thermal conductive gasket or thermal conductive silicone grease? It still depends on the scene you use and which aspects of the thermal conductive material have higher requirements.
