How to identify the stickiness of thermal conductive silicone grease

Thermally conductive silicone grease is used in a large number of industries such as household appliances and lighting fixtures, and it is an indispensable material, and its role is simply to extend the service life of products. If the viscosity of thermal grease is not suitable, it will be inconvenient to operate and abnormal to attach during the application process, so how to identify the viscosity of thermal grease?

I. Drapability

This method is very easy and convenient to identify the thermal grease with different viscosity, but for the thermal grease with close viscosity, this method may not be suitable and may cause misjudgment. Therefore, the pendulousness of thermal grease is only suitable for products with low viscosity, and the comparison of viscosity is only suitable for thermal grease with large difference.

2. viscosity size

Can the viscosity of thermal conductive silicone grease be completely characterized by viscometer test viscosity? For thermal conductive silicone grease without special functions, the higher the viscosity, the greater the data of viscometer test. Therefore, the premise of using viscosity to identify the viscosity of thermal conductive silicone grease is to understand the functional characteristics of thermal conductive grease.

3.Needle penetration

Needle penetration is an important indicator to identify the viscosity of thermal conductive silicone grease, and it is also a very effective method. The test of needle penetration of thermal conductive silicone grease is not affected by thixotropy, and it is determined by the depth of needle penetration of the cone into the thermal conductive silicone grease in free fall.
