Is thermal grease conductive? It turns out that it is related to these factors?

2024-07-09

Thermal grease is now widely used in the manufacturing industry. Thermal grease is not expensive and the amount used each time is limited. With a very small investment, you can get more stable practicality of electrical appliances. The heat dissipation performance of electrical appliances after using thermal grease is more guaranteed. Long-term operation will not cause burns due to poor heat dissipation. Users are more concerned about whether it is conductive after using thermal grease.


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

Thermal grease is mainly used in electrical appliance manufacturing. Many fields have certain requirements for the insulation of thermal grease. Only with insulation can the safety of electrical appliances be guaranteed. The main properties of thermal grease are heat conduction, flame retardancy, dustproof and moisture-proof. Users need to distinguish thermal grease from conductive grease when purchasing it. Both belong to the type of silicone grease. Conductive grease has good thermal and electrical conductivity, and can also play a corrosion-resistant role after use.


Is thermal grease conductive? It is related to the following factors

1. Formula. As a heat dissipation material, thermal grease is mainly composed of organic silicone and heat-resistant and thermally conductive materials. If silver powder is used as filler, this thermal grease has good conductivity, but it will increase conductivity. A reasonably formulated thermal grease can not only ensure electrical and thermal properties, but also play an insulating role. For example, TENSAN focuses on the research of thermal grease and provides customized thermal grease application solutions. It has a wide range of uses and can be applied to new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.


2. Usage method. The use method of thermal grease is very important. If you buy thermal grease with insulating properties, if you are not careful when applying it, there will be excess grease around the substrate that is not cleaned up in time, and the silicone oil in the grease will contaminate the exposed relay and cause electrical connection.


Some thermal greases have slight conductivity, but this type of thermal grease has too great a safety risk and cannot be widely used. Only thermal grease that conducts heat but not electricity after use can be used in various electrical appliance manufacturing.
