On January 21, 2026, Guangzhou, China - Faced with fierce competition in the global silicone oil market, China's ethyl silicone oil industry chain is building core competitiveness through technological collaboration, capacity integration, and international layout. From raw material supply to terminal applications, local enterprises have formed a complete industrial ecosystem, and some leading enterprises have begun to expand into high-end markets and overseas.


Raw material side: Collaborative development of silicon mineral resources and organic silicon monomers
The upstream of ethyl silicone oil relies on silicon mineral resources and organic silicon monomers. China has abundant reserves of silicon ore, mainly distributed in Jiangxi, Hubei and other places, providing resource guarantees for industrial development. Taking Jiangxi Xinghuo Industrial Park as an example, the park gathers enterprises such as Huahao Chemical and Jiujiang Huirong Chemical, forming a complete chain from silicon mining, organic silicon monomer production to deep processing of ethyl silicone oil. The general manager of Huahao Chemical said, "Through the mutual supply of raw materials and the recycling of waste among enterprises in the park, our production costs have been reduced by 15%, while reducing carbon emissions


Production end: Patent technology drives product iteration
In the production process, patented technology has become the key to enterprise competition. Zhejiang Zhenghe Silicon Materials Co., Ltd. has applied for a patent for "photo thermal synergistic catalytic preparation of vinyl silicone oil". By precisely controlling the polymerization reaction, it avoids side reactions and end group damage in traditional processes, and the product purity has been increased to 99.5%. It is widely used in high-end coatings and electronic packaging materials. In addition, Jiande Polymer New Materials Co., Ltd. has launched the "long-chain alkyl silicone oil", which significantly improves the hydrophobicity and wear resistance of the material by introducing a long carbon chain structure, becoming the preferred material for outdoor equipment and automotive coatings.


Application end: Local brand substitution for imports accelerates
In the terminal application market, local ethyl silicone oil brands are accelerating the replacement of imported products. For example, Gansu Longshen Rongfa Pharmaceutical Co., Ltd. uses domestically produced ethyl silicone oil as a drug excipient in the pharmaceutical field. Its biocompatibility and stability have been internationally certified, and the cost is reduced by 30% compared to imported products. In the field of consumer electronics, companies such as Huawei and Xiaomi have partnered with Shanghai Mindray Biochemical Technology Co., Ltd. to apply ethyl silicone oil to mobile phone heat dissipation modules, increasing heat dissipation efficiency by 20% and promoting the position of domestic materials in the global supply chain.


Internationalization: Parallel overseas factory construction and standard output
To expand into the international market, local enterprises have begun to establish production bases overseas. For example, Xinyuan Chemical plans to build a 50000 ton per year ethyl silicone oil factory in Southeast Asia, leveraging the local low-cost advantage to radiate to the Asia Pacific market; Zheng'an Organic Silicon promotes Chinese technology to become a global industry standard by participating in international standard setting. According to customs data, the export volume of ethyl silicone oil in China will increase by 25% year-on-year in 2025, mainly sold to Europe, America, Southeast Asia and other places.


Industry outlook: With the advancement of the "dual carbon" target and the rise of emerging industries, the ethyl silicone oil industry will usher in a new growth cycle. Enterprises need to continue to increase their R&D investment, break through the bottleneck of high-end material technology, and strengthen the synergy of the industrial chain to promote the upgrading of the industry towards green, intelligent, and high-end directions.
