On November 5, 2025, Weihai, Shandong - Xinyuan Chemical (Shandong) Co., Ltd., a leading enterprise in the domestic fluorosilicone material industry chain, announced that its independently developed "ultra-low temperature resistant ethyl silicone oil" has completed pilot testing and entered mass production stage. The gel point of this product is as low as -70 ℃, which can maintain stable lubrication performance in extremely cold environments (-70 ℃ to 150 ℃). At the same time, it has full material compatibility, and is non corrosive to metals, plastics, rubber and aerospace alloys. The flash point is as high as 265 ℃, and the high-temperature explosion-proof performance is significantly improved.


Technological Breakthrough: Facing Industry Pain Points Directly
Traditional ethyl silicone oil is prone to gelling below -50 ℃, which leads to equipment stagnation. However, through molecular structure optimization and catalyst innovation, SGC has reduced the gel point by 30 ℃, breaking through the material limitations of extreme scenarios such as Antarctic scientific research equipment and deep-sea exploration instruments. The head of the R&D team, Yu Pengfei, said, "We use dual-mode flash point technology to increase the flash point of PES2 products by nearly 100 ℃ compared to conventional silicone oil, which can meet high safety requirements such as rocket shock absorber fluid and high-temperature heat transfer medium. ”


Application Expansion: From Industry to Cutting edge Technology
This product has been tested by multiple aviation and automotive companies and has become the core raw material for high-performance shock absorbers and lubricants. In the cosmetics field, its low volatility and non-toxic characteristics make it the basic ingredient of face cream and lipstick; In the medical field, as a drug sustained-release carrier and medical device lubricant, its safety has been certified by the National Medical Products Administration.


Industrial Impact: Reshaping the Competitive Landscape
With the advantage of the entire industry chain of fluorosilicone materials, Xinyuan Chemical has reduced the cost of ultra-low temperature resistant ethyl silicone oil by 40%, and the annual production capacity is expected to reach 3000 tons. Industry analysts pointed out that this technology fills the gap of silicon-based materials in extreme environments in China, and is expected to replace imported products, promoting the high-end development of China's organic silicon industry.
