On November 7, 2025, according to the report "Market Size and Competitive Landscape of China's Silicone Oil Industry in 2025" released by Oriental Wealth Network, the market size of ethyl silicone oil, as an important branch of silicone materials, is growing at an average annual rate of 8%. The global market size of ethyl silicone oil was approximately 3 billion US dollars in 2020, and is expected to exceed 4 billion US dollars by 2025, with the Asia Pacific region accounting for over 50% and becoming the main growth engine.


Accelerated expansion of application fields
Ethyl silicone oil continues to deepen its application in industries, cosmetics, pharmaceuticals, and other fields due to its excellent chemical stability, thermal stability, and electrical insulation properties. In the industrial field, ethyl silicone oil is widely used to manufacture high-temperature lubricants, sealants, and waterproof coatings, especially in the sealing of new energy vehicle battery packs and aerospace materials. The cosmetics industry utilizes its non-toxic and odorless characteristics to develop high-end products such as skincare and makeup, meeting consumers' dual demands for safety and efficacy. In the pharmaceutical field, the market demand for ethyl silicone oil as a drug carrier and medical device lubricant is steadily increasing.


Accelerating the integration of the industrial chain
The ethyl silicone oil industry chain covers silicon ore collection, silicon material processing, organic silicon production, and downstream applications. As one of the world's largest silicon ore reserve countries, China has formed a complete industrial chain from raw materials to end products, relying on leading enterprises such as Hesheng Silicon Industry and Yunnan Energy Investment. For example, Hesheng Silicon Industry's annual production of 100000 tons of functional silicone oil project in Xinjiang includes 30000 tons of hydrogen terminated silicone oil and 20000 tons of vinyl silicone oil, further consolidating its position in the high-end market.


Policy and environmental drive
With the increasing global demand for environmental protection, the ethyl silicone oil industry is accelerating its transformation towards low-carbon. The "Safety Regulations for Production of Organosilicon Compounds" issued by China impose stricter limit standards on the volatile organic compounds (VOCs) content in products, forcing enterprises to upgrade their technology. The low ring vinyl silicone oil independently developed by Yunnan Nengtou Silicon Material Technology Development Co., Ltd. reduces volatility by 60% through full process automatic and precise control, complying with EU REACH, RoHS and other environmental regulations, and becoming the preferred material in high-end electronic packaging and biomedical fields.


News 2: Technological innovation leads the high-end development of ethyl silicone oil, and ultra-low temperature resistant products solve extreme environmental problems
On November 6, 2025, at the 4th China Western Chemical "5+N" Green Summit Forum, Xinyuan Chemical (Shandong) Co., Ltd.'s release of ultra-low temperature resistant ethyl silicone oil technology attracted industry attention. This product can maintain stable performance in extreme environments of -120 ℃, filling the gap in China and providing key material support for polar scientific research, deep-sea exploration and other fields.


Technological Breakthrough: From Laboratory to Industrialization
Yu Pengfei, Manager of Xinyuan Chemical Division, introduced that the research and development of ultra-low temperature resistant ethyl silicone oil took 3 years, and the team has overcome core technologies such as catalyst screening and polymerization process optimization. By the side of the high-temperature reactor, the R&D personnel went through thousands of rounds of parameter tuning, ultimately achieving a 30% increase in low-temperature elasticity and a 50% reduction in volatility of the product. At present, the product has passed extreme environmental testing and has been widely used in 5G communication equipment cooling modules and new energy vehicle battery pack seals. Customer feedback shows that its service life is twice as long as traditional products.


Market demand: Emerging fields generate incremental space
With the increasing global demand for extreme environmental materials, the market space for ultra-low temperature resistant ethyl silicone oil continues to expand. For example, in polar scientific expeditions, traditional silicone oil is prone to hardening and cracking at low temperatures, while Xinyuan Chemical's products can ensure the normal operation of equipment in an environment of -80 ℃. In addition, the field of deep-sea exploration requires higher pressure resistance of sealing materials, and ethyl silicone oil has become the preferred material for key components due to its excellent lubricity and chemical stability.


Industry impact: forcing collaborative innovation in the industrial chain
The breakthrough in ultra-low temperature resistant ethyl silicone oil not only enhances the international competitiveness of domestic enterprises, but also promotes collaborative innovation in the upstream and downstream of the industrial chain. For example, Yunnan Nengtou Silicon Material Technology Development Co., Ltd. has partnered with Xinyuan Chemical to jointly develop low-temperature lubricating materials suitable for the aerospace industry. At the same time, industry associations are collaborating with universities to develop the "Safety Guidelines for Application Scenarios of Ethyl Silicone Oil", which proposes differentiated indicator requirements for different fields and is expected to be released in early 2026.


Future outlook: Green and intelligent dual wheel drive
Industry experts point out that the ethyl silicone oil industry will present two major trends in the future: one is greening, reducing energy consumption and emissions through technological upgrades, and meeting global environmental regulations; The second is intelligence, using AI algorithms to optimize production processes and improve product consistency and stability. For example, the intelligent factory invested by Hesheng Silicon Industry controls the impurity content of the product below 0.01% by real-time monitoring of parameters such as reactor temperature and pressure, providing reliable guarantee for the high-end market.
