On November 13, 2025, Qujing, Yunnan Province - Driven by the "dual carbon" goal, Yunnan Province is accelerating the construction of a complete industrial chain ecology for ethyl silicone oil, relying on its abundant silicon mineral resources and green energy advantages. From silicon mining to high-end applications, Yunnan has formed a complete chain of "silicon ore industrial silicon organic silicon intermediate ethyl silicone oil downstream products". It is expected that by 2027, the output value of the organic silicon industry cluster will exceed 100 billion yuan.


Upstream integration: deep coupling of silicon ore resources and green energy
Yunnan is one of the provinces with the richest silicon reserves in China, with proven reserves accounting for over 30% of the country's total. In recent years, the local government has promoted the coordinated development of silicon mining and green energy through the "chain leader system". For example, Yunneng Silicon Materials has built the "Silicon based New Materials Industrial Park" in Qujing, which is accompanied by the construction of photovoltaic power stations and wind farms, achieving 100% green electrification of production electricity. According to calculations, this model can reduce carbon emissions from the production of ethyl silicone oil by 40% compared to traditional processes.


In the process of silicon ore processing, the "low-temperature melting technology" introduced by Yunnan can increase the purity of silicon materials to 99.99%, providing raw material guarantee for the high-end development of ethyl silicone oil. At present, Yunnan has formed an annual production capacity of 500000 tons of industrial silicon and 200000 tons of organic silicon intermediates, ranking among the top in the country.


Midstream Innovation: Intelligent Production Lines Enhance Product Competitiveness
Intelligent transformation has become an industry trend in the production of ethyl silicone oil. Yunneng Silicon Materials invested 1 billion yuan to build an "intelligent factory" that uses AI algorithms to control reaction temperature, pressure, and other parameters in real time, increasing product yield from 85% to 98%. At the same time, the factory has introduced blockchain technology to achieve full process traceability from raw materials to finished products, ensuring that products meet strict standards in fields such as medicine and food.


In addition, Yunnan has collaborated with the Institute of Process Engineering of the Chinese Academy of Sciences to develop a new process for producing ethyl silicone oil using the "catalytic cracking method". This process reduces energy consumption by 30% compared to traditional methods, and can recycle by-products, reducing the cost of each ton of product by 2000 yuan. At present, this technology has been promoted and applied in enterprises such as China Aluminum Group and Hesheng Silicon Industry.


Downstream empowerment: continuous expansion of high-end application scenarios
The rise of the Yunnan ethyl silicone oil industry cluster is driving innovative breakthroughs in downstream application fields. In the field of electronics, local enterprises have collaborated with Huawei and ZTE to develop "thermal grease" for 5G base station heat dissipation, which has a thermal conductivity 50% higher than traditional products and can reduce base station energy consumption by 15%. In the medical field, Yunnan Baiyao Group's "artificial joint lubricant" developed using ethyl silicone oil has entered the clinical trial stage and is expected to be launched in 2026.


Policy support: The "High Quality Development Plan for Organic Silicon Industry" released by the Yunnan Provincial Development and Reform Commission clearly states that a 30% financial subsidy will be given to research and development projects of ethyl silicone oil, and high-end application enterprises will be exempted from corporate income tax for 5 years. In addition, Yunnan has established a 1 billion yuan "Organic Silicon Innovation Fund" to focus on supporting the research and development of cutting-edge technologies such as low volatility and bio based ethyl silicone oil.


Enterprise News: The Chairman of Yunneng Silicon Materials stated that the company plans to invest 2 billion yuan in the next three years to build a "Global Ethyl Silicone Oil Innovation Center" in Qujing, focusing on cutting-edge fields such as shape memory silicone rubber and degradable silicone gel. The company has also launched a "Organic Silicon+AI" laboratory, with the goal of incubating 20 patents within three years.
