On April 13, 2026, Suzhou - At the Asian Silicon Technology Conference and Exhibition, ethyl silicone oil, as an important branch of organic silicon materials, has become a focus of attention in the industrial field due to its excellent lubricity, chemical corrosion resistance, and wide temperature stability. According to industry data, the global market size of ethyl silicone oil has reached 4 billion US dollars in 2024 and is expected to exceed 4.5 billion US dollars by 2025, with industrial applications accounting for over 60%.


The demand for industrial lubrication has surged
Ethyl silicone oil is widely used for lubrication of precision instruments, high-speed motors, and aerospace equipment due to its low volatility, high flash point (>265 ℃), and excellent shear resistance. For example, Wuhan Carnot Technology Co., Ltd. has successfully replaced traditional mineral oil with low viscosity ethyl silicone oil (viscosity 18-26 mPa · s) for lubrication of friction components such as clocks and synchronous motors, significantly reducing equipment wear rates and extending service life. In addition, high viscosity ethyl silicone oil (10000-100000 mPa · s) is used as a damping fluid in shock absorption systems for sensors and instruments, effectively improving equipment stability.


New energy and high-end manufacturing drive growth
With the rapid development of new energy industries such as photovoltaics and wind power, the demand for ethyl silicone oil in module packaging and thermal conductive materials continues to rise. The recently applied thermal conductive silicone grease patent for aerospace electronic equipment by Shenzhen Debang Interface Materials shows that the proportion of ethyl silicone oil in its formula reaches 3-8 parts, which can meet the heat dissipation needs in extreme space environments. Meanwhile, in the field of 5G communication, ethyl silicone oil, as an additive for high-frequency substrate materials, can significantly improve signal transmission efficiency and has become a key research and development direction for companies such as Huawei and ZTE.


Environmental regulations promote industrial upgrading
Faced with the strict restrictions of the EU REACH regulation and RoHS directive, domestic enterprises are accelerating technological iteration. Guangzhou Shengtainuo New Material Technology Co., Ltd. has optimized its production process to control the ring content (D3-D10) in ethyl silicone oil below 300ppm, fully meeting international environmental standards. We have customized the production of low ring dimethyl silicone oil and vinyl silicone oil for EU customers, and will further expand the medical grade silicone oil market in the future, "said Zhang Yi, the general manager of the company
