In the third quarter of 2026, a milestone green manufacturing progress in the global organic silicone industry was officially announced: the world's first zero-carbon epoxy polyether silicone oil industrial production line, fully driven by green electricity and with 100% by-product resource utilization, officially passed the continuous 72-hour full-load operation assessment in China. The two core dimensions of the comprehensive performance indicators of the products and the carbon emission per unit product have refreshed the global industry record, marking that China has achieved a global leading technological breakthrough in the field of green synthesis of special modified organic silicone materials. The new-generation zero-carbon epoxy polyether silicone oil produced by this production line not only has all performance indicators comprehensively surpassing similar international products, but also achieves a breakthrough result that the full-life-cycle carbon emission per unit product is 92% lower than that of traditional processes, completely breaking the technological monopoly of overseas enterprises in the field of high-end green epoxy polyether silicone oil, and providing a replicable Chinese technical solution for the global organic silicone industry to achieve the 2050 carbon neutrality goal.
As a special organic silicone additive with both epoxy reactivity and polyether hydrophilicity, epoxy polyether silicone oil is a key functional material supporting the green upgrading of high-end manufacturing industry. For a very long time in the past, the mainstream production processes of global epoxy polyether silicone oil generally adopted fossil energy-driven high-temperature and high-pressure reaction systems, which not only had low reaction selectivity and large by-product emissions, but also the carbon emission per unit product remained high for a long time. In traditional processes, the total direct and indirect carbon emissions of producing 1 ton of epoxy polyether silicone oil exceeded 12 tons, which is a typical fine chemical category with high energy consumption and high emission. With the accelerated advancement of global carbon neutrality, the downstream high-end manufacturing industry has increasingly strict carbon footprint requirements for upstream materials. High-end manufacturing industries in Europe, North America and other regions have begun to gradually include material carbon footprint into the procurement access standards. The epoxy polyether silicone oil produced by traditional high-carbon emission processes has been unable to meet the access requirements of downstream high-end markets, and the green and low-carbon transformation of the global organic silicone industry is extremely urgent.
The new generation zero-carbon production line put into operation this time has realized a disruptive full-chain innovation in the synthesis technology system. After more than ten years of continuous research, the R&D team has developed the world's first normal temperature and pressure photocatalytic directional grafting reaction system. By precisely exciting the active sites on the catalyst surface with visible light of a specific wavelength, the precise directional grafting of epoxy groups and polyether segments on the main chain of methyl silicone oil is realized under the mild conditions of 25℃ normal temperature and normal pressure, completely replacing the high energy consumption reaction system in traditional processes that requires high temperature above 180℃ and high pressure of 1.2MPa, directly reducing the energy consumption of the reaction process by 83%. At the same time, the production line adopts 100% green electricity such as wind power and photovoltaic as energy supply. The supporting by-product full resource utilization system converts all trace by-products generated in the production process into environmentally friendly additives that can be used for building materials, realizing near-zero emission in the production process, eliminating carbon emissions from the energy end to the production end in the whole chain, and finally achieving a breakthrough result that the full-life-cycle carbon footprint of the product is less than 0.9 tons CO₂/ton, far lower than the global industry average of 11.8 tons CO₂/ton.
From the feedback of the downstream application end, the implementation of the new generation of zero-carbon epoxy polyether silicone oil directly promotes the green and low-carbon upgrading in multiple high-end manufacturing fields. In the modification field of new energy photovoltaic EVA adhesive film, the zero-carbon epoxy polyether silicone oil is used as a leveling agent to prepare photovoltaic adhesive films, which not only increases the surface flatness by 71%, but also increases the full-life-cycle power generation efficiency of the modules by 2.3%. At the same time, the full-life-cycle carbon footprint of photovoltaic modules is directly reduced by 6.8%, helping downstream photovoltaic products easily meet the access requirements of the EU Carbon Border Adjustment Mechanism, greatly improving the global market competitiveness of China's photovoltaic products. In the field of high-end water-based coatings, zero-carbon epoxy polyether silicone oil is added as a wetting and dispersing agent to water-based industrial coatings, reducing the VOC emission of the coatings by 47% and increasing the scratch resistance of the coating by 54%. It has been batch applied in the coating lines of many new energy vehicle manufacturing enterprises in China, greatly reducing the carbon emission during the automobile manufacturing process. In the field of agricultural green additives, high-purity low-foam epoxy polyether silicone oil is used as a pesticide spray additive, which can increase the spreading area of pesticide liquid on the surface of plant leaves by more than 3 times, increase the effective utilization rate of pesticides by 62%, greatly reduce the usage of pesticides, and help the low-carbon development of green agriculture.
Data from industry research institutions show that the global market size of low-carbon epoxy polyether silicone oil reached 1.9 billion US dollars in 2025, and it is expected to maintain a compound annual growth rate of 14.3% in the next 8 years, with the market size exceeding 5.7 billion US dollars by 2033. With the implementation of the new generation of zero-carbon production lines in China, China will not only realize the completely independent supply of high-end zero-carbon epoxy polyether silicone oil, but also occupy a core competitive advantage in the low-carbon transformation of the global organic silicone industry with its world-leading green manufacturing technology. At present, chemical enterprises in more than 12 countries have taken the initiative to seek technical cooperation, hoping to introduce this new generation of zero-carbon epoxy polyether 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 zero-carbon epoxy polyether silicone oil is not just a single product green technology upgrading, but a landmark event for China to achieve full-chain green technology independent control in the field of special organic silicone functional materials. In the past, the green upgrading of China's organic silicone industry often focused on the end treatment of waste gas and wastewater, but this breakthrough directly penetrated to the underlying mechanism level of molecular reactions, eliminating the pain points of high energy consumption and high emission from the source, providing a brand-new technical paradigm for the subsequent green and low-carbon transformation of the entire fine chemical industry. In the future, with the continuous iteration of technology, more brand-new special organic silicone materials based on normal temperature and pressure photocatalytic synthesis technology will continue to emerge, injecting new impetus into the carbon neutrality development of the global high-end manufacturing industry.
