Is the thermal conductivity of thermal grease related to viscosity?

Professional thermal gel, thermal grease manufacturer. To understand the relationship between thermal conductivity and viscosity of thermal grease, we must first understand where the thermal conductivity or thermal conductivity of silicone grease comes from.


This article starts with the source of thermal conductivity of thermally conductive silicone grease, expounding whether the relationship between thermal conductivity and viscosity of thermally conductive silicone grease is of decisive significance.


Thermal conductive silicone grease is made of special processes such as silicone grease, fillers, and certain functional additives. After all materials are stabilized, their viscosity value is in their state. Therefore, the viscosity mainly depends on the viscosity of the silicone grease and the number of fillers. Similarly, the thermal conductivity mainly depends on the thermal conductivity of the silicone grease and the filler itself, so how to define the relationship between the two? Make the following instructions.

Regardless of other properties, the thermal conductivity of thermally conductive silicone grease, as long as the amount of thermally conductive filler is added, the thermal conductivity will naturally increase. In this case, the thermal conductivity can be adjusted by adding thermally conductive filler, indicating that the greater the viscosity, the greater the thermal conductivity. Large; For products of the same formula with the same formula, it can be regarded as a proportional relationship, but the market demand cannot be met by adding fillers. The application also includes service life, operability, stability, etc. Therefore, there will be A variety of thermally conductive silicone greases. This type of thermally conductive silicone grease has higher thermal conductivity and higher viscosity than viscosity. This also shows that the thermal conductivity and viscosity are not proportional. This is due to the choice of silicone grease and the thermal conductive filler Select relevant,


Users are warned that viscosity must not be used as an index to measure the size of the thermal conductivity. The products selected in this way may buy defective products or products with poor performance, such as longevity. There is no way to show it in the short term. Since the thermal conductivity of thermal grease has nothing to do with its viscosity, users do not know about thermal grease. First of all, you must choose a professional manufacturer to consult clearly how to choose thermal grease and how to use thermal grease. , How to control the quality of thermal grease. Since Schneider's full set of glue service has been recognized by the market, I believe that choosing Schneider will get a more accurate use plan.
