Recently, several leading domestic organic silicon new material enterprises have jointly completed the iterative upgrade of the core production process of ethyl silicone oil. The product has achieved a leapfrog improvement in core indicators such as low temperature resistance and lubrication stability. The long-term stable working temperature range covers -70 ℃ to 150 ℃, and can be widely adapted to a series of harsh application scenarios such as precision instrument operation and maintenance, aviation shock absorption systems, and special hydraulic devices.


The upgraded ethyl silicone oil product, relying on optimized hydrolysis condensation and directional molecular rearrangement processes, not only retains the inherent advantages of low surface tension, excellent chemical stability, and solubility in mineral oil at any ratio, but also significantly reduces the viscosity fluctuation amplitude in low-temperature environments. It can maintain stable and excellent lubrication performance even under extreme working conditions of -70 ℃, completely solving the long-term industry pain points of traditional lubricating materials being prone to solidification and lubrication failure in high-altitude and low-temperature environments.


At present, the upgraded ethyl silicone oil has completed multiple rounds of batch reliability testing in precision clock bearings, aviation instrument damping systems, and outdoor hydraulic equipment in high-altitude regions. The overall performance of the product far exceeds that of similar imported benchmark materials. Meanwhile, with its excellent dielectric properties, this material has also been widely used in electrical insulation infusion, special capacitor impregnation and other scenarios, becoming an indispensable key basic new material in the fields of electronic information and high-end manufacturing. Industry insiders point out that with the rapid development of downstream aerospace and precision instrument industries, the market demand for ethyl silicone oil, which combines ultimate low-temperature resistance and high lubrication stability, will continue to rise. The core breakthrough of this domestic process will further promote the process of self-control of the entire industry chain supply chain.
