Recently, several domestic fine chemical enterprises jointly released a new generation of high-purity ethyl silicone oil products, whose low temperature resistance and lubrication stability have reached the international advanced level, officially realizing the large-scale application of this type of special material in the aerospace field.


It is reported that this ethyl silicone oil product has been optimized through molecular structure to lower the pour point to below -70 ℃, and can maintain a stable fluid state in a wide temperature range of -70 ℃ to 150 ℃. It is perfectly suitable for the lubrication needs of low-temperature bearings and valves in polar exploration equipment and deep space exploration devices, and completely solves the industry pain points of traditional lubricants being prone to solidification and equipment jamming in extremely cold environments. At the same time, this product retains the high compatibility advantage of ethyl silicone oil, which is completely miscible with mineral oil and synthetic oil, without delamination or precipitation problems. It also has the characteristics of low surface tension and excellent dielectric properties, and performs well in electrical insulation, thermal conductivity and heat dissipation scenarios.


At present, the product has passed long-term working condition tests by multiple aerospace supporting units and has been successfully applied to the core lubrication of low-temperature fuel system components and polar scientific research equipment, breaking the previous situation of long-term dependence on imported high-end materials. Industry insiders say that with the maturity of the domestic fine chemical industry chain, the production cost of ethyl silicone oil is gradually decreasing. In the future, it will be popularized in more low-temperature scenarios such as cold chain transportation, precision instrument manufacturing, and military equipment, providing more reliable domestic solutions for special lubrication needs in high-end manufacturing fields.
