Non silicon thermal conductive gasketFN15， The characteristic that distinguishes it from ordinary thermal conductive silicone film is that it does not contain low molecular weight siloxane, no silicone oil, and does not evaporate. What is low molecular weight siloxane? What are the special market demands for non silicon thermal conductive gaskets without low molecular weight siloxane? Low molecular weight siloxane, commonly known as silicone oil, is an active synthetic material. The thermal conductive silicone sheets on the market generally contain low molecular weight siloxane if non silicone is not specifically emphasized, but the difference is in quantity. Because low molecular weight siloxanes are cheap and easy to use. If the content of low molecular weight siloxane (silicone oil) is too high, it will definitely contaminate the motherboard or PCB board. However, as long as the content of silicone oil is well controlled, like the thermal conductive silicone sheet of advanced technology, it is generally controlled within 0.01%, which will not affect the customer's use. However, if the customer's products are optical products, medical products, laser products, security products, etc., the requirements for silicone oil are very high, and even some medium-sized products require no silicone oil. Because low molecular weight siloxanes have excellent activity,
Thermal conductive silicone sheetWhen working, it is usually in a high-temperature environment, and low molecular weight siloxanes are easily volatile. The volatile substances will adhere to the optical lens, causing atomization. If the thermal conductive silicone film has a high content of silicone oil, the volatilization of silicone oil will directly affect the pollution and mold growth of the PCB board, and in severe cases, it can cause short circuits. Due to so many objective facts, there is an urgent need in the market for thermal conductive silicone sheets that do not contain low molecular weight silanes
