Customers often come to Dobon customer service and say that the thermal conductive silicone sheet they bought from other suppliers has oil leakage, and ask our company's testing staff to help test whether the thermal conductive pad of the supplier is qualified? For this reason, our company also bought several brands of thermal conductive silicone sheets from the market, and used our instruments to test them, including the parameter values, composition, temperature resistance, and state under high temperature of the thermal conductive silicone sheets. The following factors affect the performance of the thermal conductive silicone sheet:

The cross-linking degree of organic silicone is insufficient, and there are free unreacted vinyl silicone oil. These silicone oils will migrate to the surface of the pad when the viscosity decreases at high temperatures.

Excessive amount of hydrogen-containing silicone oil (including side hydrogen and end hydrogen), excessive reaction causes "oil leakage" and "volatilization".

Some methyl silicone oil with no active groups or even white oil as a plasticizer was added during production, which caused oil leakage. This problem is often caused by adulteration by unscrupulous suppliers.

The volatilization fraction of vinyl silicone oil or hydrogen-containing silicone oil itself is too high, and the main components are D3～D10, which will cause small molecules to slowly release substances suspected of being carcinogenic if they are in high temperature for a long time.
