Recently, domestic organic silicon new material enterprises have completed the iteration of the new generation high-purity ethyl silicone oil process, achieving stable and large-scale production. The products have been upgraded in terms of low-temperature fluidity, low volatility, and dielectric stability, further filling the material gaps in the application of special organic silicon in extreme working conditions in China.


Ethyl silicone oil, as a high-end specialty silicone oil, has excellent viscosity and temperature characteristics due to its special molecular structure of ethyl side chains. It can maintain a stable fluid state in a wide temperature range of -70 ℃ to 200 ℃. Compared with conventional methyl silicone oil, it is not easy to solidify and crystallize at low temperatures, and is compatible with mineral lubricants. It does not corrode or swell metal, rubber, or plastic substrates, and is a key medium material for precision instruments, aerospace, polar equipment, and low-temperature hydraulic systems.


The optimized ethyl silicone oil product has effectively reduced ring impurities and volatile matter through a new catalytic polymerization and deep de boiling purification process, resulting in a narrower molecular weight distribution and significantly reduced batch viscosity deviation. The product can be used as a low-temperature lubricating and shock-absorbing medium for precision instrument bearings and transmission components, eliminating pointer shaking; It can also be used as low-temperature hydraulic oil and insulation infusion fluid to serve polar scientific research equipment, aerospace low-temperature valves, deep-sea exploration equipment, avoiding the risk of low-temperature solidification failure of ordinary oil products for national science and technology enterprises At the same time, it is suitable for industrial scenarios such as rubber molding demolding and special heat transfer media.


Industry insiders have stated that in the past, high-end ethyl silicone oil was limited by synthesis processes, making mass production difficult and costly. This breakthrough in domestic technology improves product consistency, reduces downstream dependence on high-end imports, provides domestic material options for new energy storage, low-temperature laboratory equipment, and special military industry support, and helps the special manufacturing industry chain to be independently controllable.
