Recently, there has been new progress in the research and development of special organic silicon materials in China. The new generation of ultra low temperature resistant ethyl silicone oil has completed full performance testing and achieved mass production offline. This product has been optimized through molecular structure, replacing traditional methyl structures with ethyl side chains. Conventional models can maintain liquid state without solidification at -70 ℃, while special grade products have broken through the low temperature limit of -130 ℃. The viscosity increase is controlled at the leading level in the industry, completely breaking the previous situation of relying on imported high-end extreme cold working condition special lubricants.


It is reported that this ethyl silicone oil not only has extraordinary low-temperature fluidity, but also has excellent chemical stability and electrical insulation performance. In high and low temperature alternating environments, there is almost no fluctuation in dielectric loss. At the same time, it is completely inert to various industrial materials such as metals, rubber, and engineering plastics, and can be directly mixed with existing mineral oil and synthetic oil systems without the need for large-scale equipment modification to complete replacement. At present, the product has been validated in multiple high-end fields such as aerospace and polar research equipment, and will gradually be applied in core scenarios such as low-temperature hydraulic systems for spacecraft, lubrication of polar drilling equipment, and sealing of ultra-low temperature refrigeration units.


Industry organizations estimate that with the development of Arctic shipping routes, the advancement of deep space exploration projects, and the upgrading of special equipment in high-altitude regions, the domestic low-temperature resistant ethyl silicone oil market will maintain a compound annual growth rate of over 12% in the next five years. This domestic technological breakthrough will effectively fill the market gap in extreme environmental special materials and promote further improvement in the independent and controllable level of the supply chain in related high-end manufacturing fields.
