On January 9, 2026, Beijing - According to the "Analysis and Research Report on the Market Data of Ethyl Hydrogen Containing Silicone Oil in China in 2025 and the Next Five Years" released by an authoritative market research institution, the market size of ethyl silicone oil in China will reach 1.86 billion yuan in 2025, a year-on-year increase of 12.8%, with production exceeding 128000 tons and capacity utilization rate increasing to 78.3%. This growth is mainly due to the surge in demand for high-performance silicone oil in high-end fields such as new energy vehicles, electronic appliances, and biomedicine, as well as the acceleration of domestic substitution processes.


Regional market differentiation is evident, with East and South China leading the country
From a regional distribution perspective, the East China region holds the top spot with a market share of 42.6%, while Jiangsu and Zhejiang provinces contribute 31.8% of the national output value; With the advantage of the electronic and electrical industry cluster, the market share in South China has increased to 23.4%; The North China region accounts for 18.7% due to the improvement of the new energy vehicle industry chain. It is worth noting that Yunnan Nengtou Silicon Material Technology Development Co., Ltd. (hereinafter referred to as "Yunneng Silicon Material") has become a "dark horse" in the high-end market with its independently developed low ring vinyl silicone oil. The company has an annual production capacity of 5000 tons, and its products have been widely used in fields such as electronic packaging and biomedical materials, filling the market gap of ultra pure and low volatile silicone oil in China.


Technological breakthroughs drive industrial upgrading
The report points out that the industry's technological innovation capability has significantly improved, with 1247 patent applications by 2025, of which invention patents account for 68.3%. The R&D team of Yunneng Silicon Materials has successfully overcome the production difficulties of low ring vinyl silicone oil through hundreds of catalyst screenings and thousands of rounds of polymerization process optimization, reducing product volatility by 30% and meeting environmental regulations such as EU REACH and RoHS. In addition, the ultra-low temperature resistant ethyl silicone oil (-70 ℃ pour point) launched by Xinyuan Chemical (Shandong) Co., Ltd. has shown excellent performance in hydraulic systems and power fluids in extremely cold regions, further expanding the application boundaries of silicone oil.


Green manufacturing has become an industry consensus
Under the promotion of the "dual carbon" goal, the ethyl silicone oil industry is accelerating its transformation towards low-carbon. By 2025, the energy consumption per unit product will decrease by 23.6% compared to five years ago, the wastewater discharge will decrease by 28.4%, and the comprehensive utilization rate of waste will increase to 89.2%. Yunneng Silicon Materials reduces production energy consumption by 15% through full process automation control, and adopts continuous production equipment, achieving a green process application rate of 76.8%. Industry experts predict that by 2030, the carbon emission intensity per unit product of ethyl silicone oil will decrease by more than 30% compared to 2025.
