How often should the thermal grease be changed? How to judge the quality of thermal grease?


When thermal grease is used, it exhibits various properties during its service life. Once the expiration date has passed, it may not be able to be used normally. In this case, don't question the quality of the thermal grease, but the expiration date.

How often is the thermal grease replaced?

For users, after using the thermal grease for a period of time, it may dry or harden. This indicates that the service period of the thermal grease has expired and needs to be replaced in time to avoid affecting the thermal conductivity. In order for the thermal grease to perform stably, the old adhesive layer needs to be removed and reapplied.

Normally, if you choose ordinary thermal grease, you should replace it every six months to a year. If you choose a high-quality thermal grease, you should change it every two years or so. Directly clean up the old adhesive layer and apply the new adhesive layer evenly. As long as the adhesive layer is free of impurities and air bubbles, it can be put into use.

How to judge the quality of thermal grease?

If you want to judge whether a thermal grease is good or not, you have to look at the thermal conductivity. The level of thermal conductivity directly affects the heat dissipation capacity, of course, the higher the better.

Second, see if the operation method is simple. The application method of some adhesives is very simple, but they may volatilize and are not suitable for long-term use. Choose an adhesive that is flexible but difficult to apply as much as possible, and after some operation, it will be more durable.

Finally, look at the performance. For high-quality products, the various performances in the instructions can be used, rather than perfunctory. Choose high-quality products, cooperate with powerful suppliers, and feel more assured. TENSAN has been focusing on the research of heat-dissipating silicone grease for 20 years, and also provides customized heat-dissipating silicone grease application solutions. It has a wide range of uses and can be used in new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
