In December 2025, the market for ethyl silicone oil will show a strong supply-demand trend. Its excellent chemical stability, high temperature resistance, and wide range of applications make it a "star product" in the silicone oil industry. According to industry data, the global market size of ethyl silicone oil is expected to grow from approximately 3 billion US dollars in 2020 to 4 billion US dollars in 2025, with a compound annual growth rate of over 6%. As the world's largest consumer country, the Chinese market contributes more than 40% of the increase.


Industrial sector: lubricants for high-end manufacturing
In the industrial field, ethyl silicone oil has become a key material for high-end equipment manufacturing due to its excellent lubricity and high temperature resistance. For example, in the aerospace field, ethyl silicone oil is used to manufacture lubricants for key components of aircraft. Its extreme temperature resistance of -100 ℃ to 375 ℃ ensures stable operation of high thrust launch vehicles and ultra high speed aircraft in extreme environments. In addition, in automobile manufacturing, ethyl silicone oil is widely used as a high-temperature sealant in core components such as engines and transmissions, effectively preventing oil leakage and extending equipment life. Anhui Aiyota Silicone Oil Co., Ltd. recently launched the "Low viscosity Ethyl Silicone Oil IOTA 20569", which has successfully entered multiple new energy vehicle supply chains due to its excellent permeability and stability, and is used for battery pack sealing and motor lubrication.


Cosmetics field: the "invisible guardian" of beauty and personal care
Ethyl silicone oil is also widely used in the field of cosmetics. Its colorless, odorless, and non-toxic characteristics make it an ideal additive for skincare and makeup products. For example, as a modified product of ethyl silicone oil, phenyl silicone oil is widely used by international beauty brands because it can improve the gloss and film-forming property of lipstick and sunscreen. New Yaqiang Chemical Co., Ltd. recently revealed at a performance briefing that its phenyl silicone oil products have achieved large-scale sales and are continuously upgrading their formulations to meet market demands for "fast film formation, waterproof and breathable" performance. In addition, ethyl silicone oil can also be used to manufacture medical devices such as silicone catheters and baby pacifiers, and its biocompatibility and aging resistance provide guarantees for product safety.


Emerging fields: the "booster" of green energy
With the acceleration of global energy transition, the application of ethyl silicone oil in the field of new energy continues to expand. In the photovoltaic industry, ethyl silicone oil, as an encapsulation material for silicone solar cells, can improve the weather resistance and power generation efficiency of components; In the field of lithium batteries, as an electrolyte additive, it can improve the charging and discharging performance and cycle life of batteries. Yunnan Nengtou Silicon Material Technology Development Co., Ltd. recently announced that its independently developed "low ring vinyl silicone oil" has achieved large-scale production, with an annual production capacity of 5000 tons. Due to its low volatility and high stability, this product is widely used in high-end electronic packaging and biomedical materials fields, providing key material support for the new energy industry chain.


Industry outlook: Technology driven, high-end transformation accelerating
Industry experts point out that the growth momentum of the ethyl silicone oil market mainly comes from two aspects: one is the continuous expansion of downstream application fields, and the other is the increase in product added value brought about by industry technological upgrades. In the future, with the promotion of the "dual carbon" goal, the ethyl silicone oil industry will accelerate its green transformation, reduce energy consumption and emissions through catalytic technology optimization, production process improvement, and other means, while developing towards high-end and differentiated directions. For example, the "ultra-low temperature resistant ethyl silicone oil" being developed by Xinyuan Chemical (Shandong) Co., Ltd. can meet extreme environmental needs such as polar scientific research and deep-sea exploration, and is expected to be industrialized by 2026.
