In July 2026, China's epoxy silicone oil industry officially released the self-discipline convention for green manufacturing across the entire industry, and simultaneously launched the low-carbon transformation technical standards covering the whole production process. This marks that China's epoxy silicone oil industry has completely bid farewell to the traditional high-pollution and high-energy-consumption production mode, and fully entered a new stage of low-carbon high-quality development centered on low VOC emissions, resource recycling and popularization of green processes. According to calculations by industry associations, after the completion of the entire industry's green transformation, the unit energy consumption of domestic epoxy silicone oil products will decrease by 38%, the wastewater discharge during production will be reduced by 72%, and the carbon emission intensity of the entire industrial chain will be 55% lower than that in 2023, establishing significant local advantages in the global green competition for special organosilicon materials.
The traditional production process of epoxy silicone oil has long had three major environmental pain points: first, the chlorohydrin synthesis route widely adopted in the early stage will generate a large amount of chlorine-containing and salt-containing wastewater, which has high subsequent treatment costs and is difficult to meet discharge standards; second, the batch reactor production mode has poor temperature control accuracy and many side reactions, which not only makes it difficult to guarantee product consistency, but also releases a large amount of volatile organic waste gas during the production process; third, the industry generally lacked waste liquid recycling mechanisms in the past, and most of the organosilicon residual liquid after the reaction was directly treated as hazardous waste, which not only caused resource waste, but also brought huge environmental pressure. With the continuous advancement of China's "Dual Carbon" goals and the escalating global green compliance requirements for chemical products, the traditional production mode has been completely unable to adapt to the needs of industrial development, making the green manufacturing transformation of the entire industry extremely urgent.
The green manufacturing upgrade implemented across the entire industry this time has achieved systematic breakthroughs around three core technical directions: first, the large-scale industrial popularization of continuous flow reactors. The millisecond-level precise temperature control technology has increased the synthesis reaction selectivity of epoxy silicone oil to 96%, the equipment utilization rate has jumped from 45% of the traditional batch process to 93%, the production energy consumption per unit product has directly decreased by 35%, and the unorganized VOC emissions caused by material leakage during the batch reaction process have been completely eliminated; second, the construction of a full closed-loop resource recycling system. The widely promoted organosilicon residual liquid recycling process in the industry adopts membrane separation + catalytic cracking technology to re-convert the organosilicon by-products generated during production into synthetic raw materials for recycling, increasing the comprehensive utilization rate of raw materials to 98.5%, and the hazardous waste generation volume has decreased by 91% compared with before the transformation; third, the full application of low-VOC post-treatment processes. The combined process of solvent-free bulk polymerization coupled with devolatilization system ensures that the VOC residue in the final epoxy silicone oil product is less than 10% of the national control standard, fully meeting the environmental protection requirements of high-end household and children's product contact additives.
Epoxy silicone oil products produced with upgraded green processes have achieved large-scale applications in multiple downstream scenarios with extremely high environmental protection requirements. In the field of high-end textile soft finishing, the ecological textile auxiliaries prepared from low-VOC epoxy silicone oil are used for finishing infant clothing fabrics. The formaldehyde content and volatile harmful substance residues of the fabrics all pass the highest level certification of OEKO-TEX 100, while the tear strength of the fabrics is increased by 30%, and the softness remains above 92% after 50 repeated washes. Related products have been batch supplied to the global high-end textile supply chain. In the anti-aging coating scenario for wind turbine blades, high-purity epoxy silicone oil produced by green processes is used as a coating modified component, which can extend the UV aging resistance life of wind turbine blade coatings to 25 years, fully adapting to the full life cycle operation requirements of offshore wind power projects for more than 20 years, while the carbon emission during coating production is 42% lower than that of traditional systems.
The latest forecast released by industry associations shows that with the full maturity of the green manufacturing system, the domestic epoxy silicone oil market will maintain an average annual compound growth rate of 13.2% from 2026 to 2030, and the overall market size will exceed 8.7 billion yuan by 2030. Among them, the proportion of high value-added products produced by green low-carbon processes will increase from the current 32% to 65%. Relying on the cost and compliance advantages brought by green processes, the global market competitiveness of domestically produced epoxy silicone oil has been greatly improved. In the first half of 2026, the product export volume increased by 124% year-on-year, and the products are exported to more than 30 countries and regions in Europe, Southeast Asia, North America and other regions, rapidly growing from a follower in the global mid-to-low-end market to a core supplier in the global special organosilicon material green supply chain.
