In the third quarter of 2026, the landmark industrialization project in China's special organic silicone material sector officially passed the 72-hour full-load continuous operation assessment, marking that China has achieved global leading technological breakthroughs in two core fields: green synthesis of three core categories of high-purity amino-modified methyl silicone oil, epoxy-modified methyl silicone oil and polyether-modified methyl silicone oil, and full resource utilization of low-molecular substances. The series of special modified methyl silicone oils produced by this project not only have all performance indicators comprehensively surpassing similar international products, but also achieve a breakthrough result that the carbon emission per unit product is 65% lower than that of traditional processes, completely breaking the nearly 50-year technological monopoly of overseas enterprises in the field of high-end modified methyl silicone oil, and providing a brand-new Chinese technical path for the green and low-carbon transformation of the global organic silicone industry.
As the most abundant functional branch in the organic silicone material family, modified methyl silicone oil can precisely meet the special performance requirements of different downstream scenarios by introducing different active functional groups on the methyl main chain, and is a key functional material supporting the upgrading of high-end manufacturing industry. For a very long time in the past, the production technology of global high-end modified methyl silicone oil has long been controlled by a few overseas chemical giants. Traditional production processes generally have common industry problems such as low grafting reaction selectivity, high residual unreacted low-molecular substances, and high energy consumption and carbon emission. As the world's largest high-end manufacturing base, China's demand for high-purity special modified methyl silicone oil has continued to grow at a high speed for a long time. However, restricted by technical shortcomings, a large number of high-end categories are completely dependent on imports, which not only leads to high procurement costs, but also the stability of the supply chain cannot be guaranteed for a long time, seriously restricting the development speed of downstream strategically emerging industries such as biomedicine, advanced semiconductors and new energy.
The new generation production line put into operation this time has achieved disruptive technological innovation in the grafting catalytic system. After more than ten years of continuous research, the R&D team has developed a brand-new single-atom anchored palladium-based catalytic system. By precisely regulating the distribution of active sites on the catalyst surface, 100% directional grafting of active functional groups on the main chain of methyl silicone oil is realized, completely avoiding the generation of a large number of misgrafted by-products in traditional processes. The atomic utilization rate of the reaction is increased from 58% of the traditional process to 99.6%, almost eliminating the generation of waste from the source. At the same time, the project is equipped with the world's first closed-loop low-molecular recycling system, which converts all trace unreacted monomers generated in the production process into basic raw materials that can re-enter the synthesis process, realizing near-zero emission in the production process and completely solving the long-standing environmental protection problem that plagues the production of modified methyl silicone oil.
From the feedback of the downstream application end, the implementation of the new generation of high-purity special modified methyl silicone oil directly promotes the product performance upgrading in multiple high-end manufacturing fields. In the textile printing and dyeing field, the high-purity amino-modified methyl silicone oil is used to prepare high-end fabric softener, the fabric treated with it has more than 120 times of washing resistance, and the softness of the hand feel far exceeds that of traditional similar products. It has been batch applied in many leading textile enterprises in China, greatly improving the added value of high-end textiles. In the field of advanced semiconductors, the electronic-grade high-purity polyether-modified methyl silicone oil is used to prepare the additive for chip chemical mechanical polishing slurry, which shows excellent performance in the chip polishing process of 28nm advanced process, with the surface roughness of the polished wafer controlled below 0.2nm, fully meeting the mass production demand of domestic chip manufacturing enterprises, and providing key material support for the independent controllable development of China's semiconductor industrial chain. In the field of new energy, the high-purity epoxy-modified methyl silicone oil is used to prepare the modifier for wind turbine blade coating, which increases the sand erosion resistance of the wind turbine blade by 52%, and at the same time greatly extends the service life of wind power equipment, laying a foundation for the large-scale mass production of the next generation of large-megawatt wind power equipment.
Data from industry research institutions show that the global market size of high-end special modified methyl silicone oil reached 5.2 billion US dollars in 2025, and it is expected to maintain a compound annual growth rate of 11.7% in the next 7 years, with the market size exceeding 11.8 billion US dollars by 2032. With the implementation of the new generation of green production lines in China, China will not only realize the completely independent supply of high-end special modified methyl silicone oil, but also occupy a core competitive advantage in the low-carbon transformation of the global organic silicone industry with its leading green manufacturing technology. At present, chemical enterprises in many overseas countries have taken the initiative to seek technical cooperation, hoping to introduce this new generation of green modified methyl silicone oil production technology to help the local organic silicone industry achieve the carbon neutrality goal.
Authoritative industry experts said that this industrialization breakthrough of special modified methyl silicone oil is not just a single product technology upgrading, but a landmark event for China to achieve full-chain independent technological control in the field of organic silicone functional materials. In the past, the technological upgrading of China's organic silicone industry often focused on downstream end products, but this breakthrough directly penetrated to the underlying level of precise molecular structure regulation, providing unlimited possibilities for the subsequent innovative development of the entire organic new material industry. In the future, with the continuous iteration of technology, more brand-new special methyl silicone oil materials based on precise modification technology will continue to emerge, injecting new impetus into the development of the global high-end manufacturing industry.
