On January 21, 2026, Shanghai, China - With the rapid development of the global silicone material industry, ethyl silicone oil, as an important branch of special silicone oil, is becoming a "new favorite" in many industrial fields due to its excellent low-temperature resistance, electrical insulation, and chemical stability. According to industry data, the global market size of ethyl silicone oil has exceeded 4 billion US dollars by 2025, and is expected to continue to grow at an average annual rate of 6% in the next three years. As the world's largest producer and consumer, China has particularly outstanding market potential.


Technological breakthrough: Ultra low temperature resistant ethyl silicone oil leads high-end applications
In the high-end field, the technological innovation of ethyl silicone oil continues to break through. For example, Xinyuan Chemical (Shandong) Co., Ltd. recently announced that its research and development of ultra-low temperature resistant ethyl silicone oil has achieved large-scale production. The product can maintain stable performance in extreme environments of -150 ℃ and is widely used in aerospace, deep-sea exploration and other scenarios. Traditional silicone oil is prone to brittleness in ultra-low temperature environments, but our product solves this problem through molecular structure optimization and has been supplied to multiple military enterprises, "said Yu Pengfei, the business unit manager of the company


In addition, Dongguan Zheng'an Organic Silicon Technology Co., Ltd. has applied for a patent for "End Vinyl Silicone Oil with Side Chain Silicon Hydrogen Bonds", further expanding the application of ethyl silicone oil in liquid silicone rubber. This technology significantly improves the mechanical properties of silicone rubber by introducing silicon hydrogen bonds, while reducing structural phenomena, providing high-performance material solutions for fields such as battery sealing and electronic component protection in new energy vehicles.


Market Dynamics: Parallel Expansion of Production Capacity and Environmental Protection Requirements
Domestic production capacity of ethyl silicone oil continues to expand. Jiangxi Huahao Chemical Co., Ltd. recently announced that its expansion project with an annual output of 15000 tons of organic silicon materials has been officially put into operation, including the addition of a 4500 tons/year hydroxyl silicone oil production line, and some products will be used for the raw material supply of ethyl silicone oil. At the same time, industry environmental standards are becoming increasingly strict, and companies are increasing their investment in environmental protection. For example, Huahao Chemical has added condensation and activated carbon adsorption devices in its expansion project to ensure that exhaust emissions meet standards and promote the green transformation of the industry.


Downstream applications: Full coverage from industrial lubrication to consumer electronics
The downstream application scenarios of ethyl silicone oil are constantly enriching. In the industrial field, it is widely used as a lubricant, release agent, and sealant in industries such as automobile manufacturing and mechanical processing; In the field of consumer electronics, ethyl silicone oil has become an ideal material for heat dissipation coatings on smartphones and wearable devices due to its non toxicity and non corrosiveness; In the field of medicine, its biocompatibility advantage is outstanding, which can be used for lubrication of medical devices and drug sustained-release carriers.


Market analysis institutions point out that with the rise of emerging industries such as 5G communication and new energy vehicles, the demand for ethyl silicone oil will be further released. It is expected that by 2028, the market size of ethyl silicone oil in China will exceed 15 billion yuan, becoming the fastest-growing regional market in the world.
