With the continuous deepening of the application of organic silicon new materials in cutting-edge fields such as aerospace and precision electronics, ethyl silicone oil (CAS: 63148-61-8) is ushering in a new round of market explosion. According to the latest industry data, the market size of ethyl hydrogen silicone oil in China has reached 274 million yuan in 2024, and the global market size has exceeded 1.092 billion yuan. It is expected that the global market will climb to 1.865 billion yuan by 2030.


Ethyl silicone oil, as a polydiethylsiloxane, has a working temperature range of -60 ℃ to 150 ℃ and a flash point exceeding 265 ℃. It has excellent characteristics such as low viscosity with temperature changes, low vapor pressure, low surface tension, and high compressibility. Compared with dimethyl silicone oil, its low temperature resistance and lubricity are more outstanding, and it can be miscible with mineral oil in any proportion, which makes it highly favored in the high-end lubrication field.


It is worth noting that in January 2026, Shenzhen Debon Interface Materials applied for a thermal conductive silicone grease patent for aerospace electronic equipment. Its formula explicitly uses ethyl silicone oil with a viscosity of 50-1000 mPa · s as a key component, aiming to meet the heat dissipation needs in extreme space environments. This innovative application marks the leap of ethyl silicone oil from traditional release agents and lubricants to aerospace grade functional materials.


At present, the main production capacity of ethyl silicone oil in China is concentrated in Hubei, Jiangsu, Shanghai and other places, with large-scale supply from enterprises such as Hubei Jusheng Technology, Hubei Xinkang Pharmaceutical and Chemical, and Kandis Chemical (Hubei). The products on the market cover industrial grade, daily chemical grade, and scientific research reagent grade, with packaging specifications ranging from 100g to 200KG, and a price range of about 20-500 yuan/kg, meeting the needs of multi-level customers.


Industry insiders point out that the penetration rate of ethyl silicone oil in healthcare, automotive, personal care, aerospace and other fields continues to increase, coupled with the high-speed growth of the ethyl hydrogen silicone oil sub segment, this category is expected to maintain double-digit growth in the next five years.
