Since the beginning of 2026, the market for ethyl silicone oil has undergone a sudden change. According to the latest quotation from Gaide Chemical Network, the price of low viscosity ethyl silicone oil (18-26 mPa · s) in Hubei region has dropped to 20-29 yuan/kg, while the price of high viscosity products (10000-10000 mPa · s) remains in the range of 50-100 yuan/kg. Two years ago, the price of products of the same specification was generally above 18500 yuan/ton. Behind the price drop is the dual driving force of capacity release and technological breakthroughs.


Hubei is becoming the "Silicon Valley" of global ethyl silicone oil. A complete ethyl silicone oil industry chain has been formed from Tianmen to Wuhan, from Yichang to Jingmen. Hubei Xinkang Pharmaceutical Chemical Co., Ltd. focuses on the "Jusheng brand" ethyl silicone oil as its main product, with a purity of up to 99% and heavy metal control within 1ppm. It has established long-term cooperation with international giants such as MERCK in the United States and SK in South Korea; Hubei Jusheng Technology, with 13 years of deep industry cultivation, offers highly competitive prices; Kandis Chemical relies on the ISO9001 quality system, and its products are widely adopted by top research institutions such as the Chinese Academy of Sciences, Tsinghua University, and Peking University.


The technological breakthroughs are equally exciting. The traditional production of ethyl silicone oil relies on the preparation of Grignard reagents from chloroethane and magnesium metal, which is complex and costly. Nowadays, the direct synthesis route - co hydrolysis and condensation of diethyldichlorosilane and triethylchlorosilane, followed by molecular rearrangement catalyzed by sulfuric acid - is becoming the mainstream in the industry, greatly reducing the production threshold. Anhui Aiyota Silicone Oil Co., Ltd. has launched a full range of ethyl silicone oil product lines, covering 16 categories, from low viscosity instrument oil to high viscosity damping fluid.


From the application perspective, the "irreplaceability" of ethyl silicone oil is being redefined. It is not only the "blood" of precision instruments and efficient release agent for rubber and plastic, but also the core component of hydraulic oil, shock-absorbing oil, and capacitor infusion fluid. In April 2026, the Qingdao Research Institute of Sichuan University, in collaboration with Hangzhou Jiayuan Technology, applied for a patent for branched vinyl silicone oil, which also identified the compounding technology of phenyl vinyl silicone oil and ethyl silicone oil as a key innovation point, aiming to significantly improve the waterproof, sealing, and mechanical properties of coating resins.


Exploring prices does not mean compromising quality. On the contrary, when the Hubei industrial cluster enters the 20 yuan era with the advantage of scale, the pattern of the global high-end lubrication market is being rewritten. The "silicone oil revolution" led by Chinese companies has just begun.
