Thermal conductive gasket and thermal conductive silicone grease are both materials used for heat conduction and heat dissipation. In the current market, both of these thermal conductivity materials have been used. However, due to the differences in the production process and materials between them. There are also differences in the use of this heat-conducting material. Which of the two materials is better? Let's see the difference between the two first.

Which is better, heat conductive gasket or heat conductive silicone grease?

So I first know about this thermal gasket, which is a kind of soft material with good thermal conductivity. This composite material also has good insulation. The material is mainly made of boron nitride with high thermal conductivity and silica gel.

Look at thermal grease, which is a heat-conducting material that uses silicone. Good wettability, for some contact surface uneven place is a good application.

From the above point of view, heat conduction gasket and heat conduction grease actually have their own unique place, can not say which is good or bad. Let's take a look at the advantages and disadvantages of both, and then judge further.

In insulation, the insulation of heat conductive gasket is better than that of heat conductive silicone grease. This is mainly because of the presence of metal in conductive silicone grease, natural insulation is poor. Secondly, when in use, silicone gasket is more convenient, because it can be cut according to the size needs. And thermal grease is needed to apply carefully. Otherwise, it will dirty components and even short circuit.

There is also the service life, because the thermal conductive gasket is solid, and thermal conductive silicone grease is a kind of solid-liquid mixture of materials, compared with silicone grease silicone oil will be more volatile. Therefore, the use of thermal conductivity grease for a long time is prone to aging, and the life is shorter. And then there's the heat conduction. Under the same thermal conductivity, the thermal conductivity of thermal gasket is worse than that of thermal conductivity silicone grease. This is mainly because the thermal resistance of thermal grease is small.

The characteristics of the two are that each has its own advantages, if the thermal conductive gasket and thermal conductive silicone grease which is better? It still depends on the scene you are using, which aspects of the thermal conductivity material have higher requirements.
