On January 15, 2026, Dongguan, China - With the organic silicon industry entering a stage of high-quality development, technological innovation and patent layout in the field of ethyl silicone oil have become the core focus of enterprise competition. Recently, several domestic enterprises have been promoting the upgrading of the industry towards high-performance and green direction by developing new types of ethyl silicone oil products and production processes.


Patent technology breaks through performance bottlenecks
In January 2026, Dongguan Zheng'an Organic Silicon Technology Co., Ltd. applied for a patent for "End Vinyl Silicone Oil with Side Chain Silicon Hydrogen Bonds" (Publication No.: CN121270926A), which attracted industry attention. This technology significantly improves the mechanical properties of liquid silicone rubber by introducing silicon hydrogen bonds into the molecular side chains, while reducing the phenomenon of structuring. According to the patent abstract, this product can be applied in fields such as battery sealing for new energy vehicles and medical grade silicone products, with huge market potential.


At the same time, Jiujiang Yuren New Materials Co., Ltd. has obtained the patent for "ultra-low viscosity ethylene based silicone oil automatic feeding device" (authorization announcement number: CN223717046U), which has shortened the mixing time by 30% through optimizing the production process, significantly reducing energy consumption and production costs. This technological breakthrough provides the possibility for large-scale industrial production or reshapes the industry's cost competition landscape.


High end fluorinated products have become a research and development hotspot
At the 24th Organic Silicon Fine Chemicals Technology Exchange Conference in 2024, Yu Pengfei, Manager of Xinyuan Chemical Division, shared the latest research results on "ultra-low temperature resistant ethyl silicone oil and fluorinated silicone oil". The fluorosilicone copolymerization technology developed by their team extends the temperature resistance range of ethyl silicone oil to -100 ℃ to 200 ℃, while improving the chemical stability of the material. This product has been certified by military enterprises and may be used in deep-sea exploration equipment and spacecraft thermal protection systems in the future.


Industry concentration continues to increase
According to Tianyancha data, by 2025, the CR5 (top five companies' market share) of China's ethyl silicone oil industry will reach 65%, an increase of 12 percentage points compared to 2020. Top enterprises further expand their advantages through mergers and acquisitions, as well as technology integration. For example, Hubei Jusheng Technology Co., Ltd. achieved full market coverage in the central China region by acquiring two regional manufacturers. Small and medium-sized enterprises, on the other hand, focus on niche areas, such as the "high viscosity ethyl silicone oil" developed by Wuhan Shuou Technology Co., Ltd., which has already occupied 30% of the textile additive market share.


Dual support from policies and capital
In November 2025, the National Development and Reform Commission released the "14th Five Year Plan" for the development of the organic silicon industry, which clearly listed ethyl silicone oil as a key development category for high-end new materials and proposed the goal of achieving an import substitution rate of over 80% by 2028. In the capital market, the financing amount of the organic silicon sector in 2025 will reach 12 billion yuan, of which the proportion of ethyl silicone oil projects exceeds 40%, demonstrating investors' strong confidence in the industry's prospects.


Future Prospects
Industry insiders analyze that with the promotion of the "dual carbon" target, the application of ethyl silicone oil in areas such as photovoltaic inverter heat dissipation and hydrogen energy storage and transportation will accelerate. Enterprises need to accelerate the research and development of green production processes, such as using bio based raw materials to replace traditional petrochemical raw materials, in order to meet international standards such as EU carbon tariffs. It is expected that by 2028, the global market size of ethyl silicone oil will exceed 5 billion yuan, and the global market share of Chinese enterprises is expected to increase to 45%.
