Is thermally conductive silicone conductive? It turns out that it has something to do with these factors?

Nowadays, thermal grease is commonly used in the manufacturing industry. With a small investment, you can get a more stable utility of the appliance. The thermal performance of the appliance is more secure after using thermal grease, and there will be no burnout due to poor heat dissipation after a long period of operation.

Is thermal grease conductive? Does it need to have conductive properties?

Thermal conductive silicone grease is mainly used in the manufacturing of electrical appliances, and many fields have certain requirements on the insulation of thermal conductive silicone grease. The main properties of thermally conductive silicone grease are thermal conductivity, flame retardant, dustproof, and moisture resistance. When buying thermally conductive silicone grease, users need to distinguish it from conductive silicone grease. Both are types of silicone grease. Conductive silicone grease has good thermal and electrical conductivity, and can also be used to resist corrosion.

Whether the thermally conductive silicone grease is conductive or not is related to the following factors

1Formulation. Thermal conductive silicone grease is a heat dissipation material, the main component is the organic silicone and heat-resistant, thermally conductive material composition. If the silver powder is used as filler, this kind of thermal conductive silicone grease has good conductivity, but it will increase the conductivity. Some thermally conductive silicone greases are slightly conductive, and the safety risk of using such thermally conductive silicone greases is too great to be widely used. Only thermally conductive silicone grease that is not conductive after use can be used in the manufacture of various electrical appliances.

2How to use. It is very important to use thermal conductive silicone grease. If you do not pay attention when you buy the thermally conductive silicone grease with insulating properties, and if you do not clean up the excess silicone grease around the substrate in time, the silicone oil in the silicone grease will pollute the exposed relays and cause even electricity.
