On February 24, 2026, Beijing, China - With the rapid development of the global high-end manufacturing industry, ethyl silicone oil, as a high-performance silicone material, is experiencing explosive growth in market demand. According to industry data, the global market size of ethyl silicone oil has exceeded 4 billion US dollars by 2025, and it is expected to continue to grow at an average annual rate of over 6% in the next three years, with the contribution rate of the Chinese market exceeding 30%.


Industrial sector becomes the core driving force
Ethyl silicone oil continues to deepen its application in the industrial field due to its excellent lubricity, low temperature resistance (stable operation below -80 ℃), and dielectric properties. In automobile manufacturing, ethyl silicone oil is widely used in engine seals, shock absorption systems, and high-temperature lubrication scenarios, significantly improving equipment life by replacing traditional mineral oils; In the electronics industry, its low volatility (vapor pressure of only 0.532mmHg at 25 ℃) and ultra pure characteristics have become key materials for high-end chip packaging and liquid silicone rubber (LSR) injection molding.


Yunnan Nengtou Silicon Material Technology Development Co., Ltd. (hereinafter referred to as "Yunneng Silicon Material") recently announced that its independently developed low ring vinyl silicone oil annual production capacity has exceeded 5000 tons, with a product purity of 99.9%, successfully entering the electronic packaging and biomedical materials markets. The head of the company's R&D team stated, "Through full process automation control, we have solved the volatility and environmental compliance issues caused by the high ring content of traditional vinyl silicone oil. Our products have passed the EU REACH certification and our customers include multiple international semiconductor giants. ”


The synergistic effect of the industrial chain is significant
The upstream of the ethyl silicone oil industry chain relies on silicon mining and production of organic silicon monomers. As the world's largest supplier of silicon materials, China accounts for over 60% of the global production capacity. Hubei, Jiangsu, Shanghai and other places have gathered leading enterprises such as Hubei Fangde New Materials and Nanjing Bermuda Biotechnology, forming a complete layout from raw materials to end products. In terms of downstream applications, Shenzhen Debang Interface Materials Company recently applied for a patent for thermal conductive silicone grease for aerospace electronic equipment, which uses ethyl silicone oil as the core component and adds zinc oxide particles to achieve efficient heat dissipation in extreme space environments.


Environmental policies promote technological upgrading
Faced with the global carbon neutrality goal, the ethyl silicone oil industry is accelerating its transformation towards green manufacturing. The "methyl vinyl silicone oil production tail gas recovery and treatment device" developed by Inner Mongolia Hengyecheng Organosilicon Co., Ltd. has increased the tail gas adsorption efficiency by 40% through the U-shaped adsorption flow path design, reducing the active carbon consumption by 200 tons annually. The relevant patents have been authorized by the China National Intellectual Property Administration. Industry experts point out that in the next three years, low ring, low volatility, and biodegradable ethyl silicone oil products will become the mainstream in the market, and enterprises with high technological barriers will have a competitive advantage.
