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.
