On December 29, 2025, as the market size of ethyl silicone oil continues to expand, upstream and downstream enterprises in the industrial chain accelerate collaborative innovation, and the regional industrial cluster effect becomes increasingly significant. A complete industrial chain covering "silicon mining organic silicon monomers ethyl silicone oil high-end products" is accelerating its formation in the eastern coastal areas of China, from raw material supply to terminal applications.


Upstream: Integration of Silicon Mineral Resources and Breakthrough in Individual Technologies
As the core raw material of ethyl silicone oil, the mining and purification technology of silicon ore directly affects the product quality. With abundant silicon mineral resources, Xinjiang has become an important global supply base for silicon-based materials. Xinjiang Zhuoneng Coal Industry Co., Ltd. recently announced that its wholly-owned subsidiary, Xinjiang Eastern Hesheng Silicon Industry, has officially put into operation a 15 million ton silicon ore project. The project adopts internationally advanced flotation technology, with a silica purity of 99.8%, which can meet the demand for an annual production of 500000 tons of organic silicon monomers. At the same time, the monomer synthesis technology continues to break through, and the "low-energy methylchlorosilane synthesis process" developed by a certain enterprise reduces the energy consumption per unit product by 20%. The related patented technology has been exported to Southeast Asian countries.


Midstream: Modified technology drives product iteration
Faced with the diversified demand for performance in downstream markets, ethyl silicone oil modification technology has become a competitive focus. Zhejiang Lingzhiyuan Technology Co., Ltd. has successfully developed "Nano particle Modified Ethyl Silicone Oil" through joint laboratory construction with universities. The friction coefficient of this product has been reduced to 0.05, and it has been applied in the lubrication system of high-speed railway bearings. Another company focuses on the research and development of bio based ethyl silicone oil. Its products synthesized from vegetable oil have obtained EU ECOCERT certification and are in high demand in the personal care market. According to statistics, the number of patent applications for ethyl silicone oil modification in China will increase by 35% year-on-year in 2025, of which 30% will come from small and medium-sized enterprises, and innovative vitality will continue to emerge.


Downstream: Deep integration of regional clusters and terminal applications
In the field of terminal applications, the effect of regional industrial clusters is accelerating. Taking Taixing, Jiangsu as an example, relying on the circular economy industry demonstration zone, a closed-loop industrial chain of "ethyl silicone oil sealant new energy vehicles" has been formed locally. As a core enterprise in the cluster, Lithua New Materials Co., Ltd.'s annual production of 200000 tons of ethyl silicone oil project not only meets its own sealant production needs, but also provides raw material support for more than 20 surrounding automotive parts enterprises. The company's general manager introduced that by transporting raw materials such as hydrogen and silicon tetrachloride through pipelines within the park, the unit product cost has been reduced by 15% and carbon emissions have been reduced by 20%. This "chain development" model is being replicated in many places, with Shandong, Guangdong and other regions planning to build specialized industrial parks for ethyl silicone oil. It is expected that by 2026, China will form three industrial clusters of ethyl silicone oil with an output value exceeding 10 billion yuan.


International Cooperation: Integrating Technology Introduction and Market Expansion
In the international market, Chinese ethyl silicone oil companies are accelerating their global layout through technological cooperation and mergers and acquisitions. A certain enterprise recently completed the acquisition of a special silicone oil company in Germany, obtaining its core technology of high-temperature resistant ethyl silicone oil. The product's temperature resistance limit has been increased to 350 ℃, directly benchmarking international giants. Another company has cooperated with Southeast Asian countries to build an ethyl silicone oil production base, taking advantage of local cheap labor and tariff advantages, reducing product costs by 18% compared to China, and has successfully entered the mid to high end markets in Europe and America. According to customs data, China's export of ethyl silicone oil will increase by 25% year on year in 2025, of which 60% will be exported to countries along the "the Belt and Road".


Challenges and Opportunities: Green Transformation and High End Breakthrough
Despite the broad market prospects, the industry still faces environmental pressures and the challenge of relying on imported high-end products. To this end, multiple enterprises have increased their R&D investment, laid out green production and high-end substitution. The "closed-loop recycling process" developed by a certain enterprise can convert the waste of ethyl silicone oil production into high-purity raw materials with a recovery rate of 95%. This technology has won the National Science and Technology Progress Award. In the high-end field, domestic enterprises are breaking through technological barriers. A company has developed "electronic grade ethyl silicone oil" with a purity of 9N, which has been successfully applied to chip packaging and breaks the foreign monopoly. Industry experts point out that with the promotion of the "dual carbon" target and the acceleration of domestic substitution, the ethyl silicone oil industry will usher in a new round of reshuffle, and enterprises with technological reserves and industrial chain integration capabilities will stand out.
