In July 2026, China's fluorosilicone oil industry officially released a full-chain green manufacturing standard system, covering the entire production process from raw material synthesis, polymerization reaction to post-treatment purification. This marks that China's fluorosilicone oil industry has completely bid farewell to the traditional high-pollution and high-energy-consumption production mode, and fully entered a new green development stage centered on low environmental impact and full life cycle carbon emission reduction. According to calculations by industry associations, after the completion of the entire industry's green transformation, the unit production energy consumption of fluorosilicone oil products will decrease by 42%, the fluorine-containing wastewater discharge during production will be reduced by 78%, and the carbon emission intensity of the entire industrial chain will be 57% lower than that in 2023. It has established significant local advantages in the green competition of global fluorosilicone functional materials, directly promoting the low-carbon technology upgrading of downstream industries such as domestic new energy batteries and intelligent vehicle surface treatment.
The traditional production process of fluorosilicone oil has long had three major environmental pain points. First, the widely adopted electrochemical fluorination synthesis route in the early stage has an energy consumption 3.7 times that of the current green process. A large amount of perfluorooctane sulfonic acid by-products that are difficult to degrade will be generated during the production process, resulting in extremely high subsequent environmental protection treatment costs and the risk of leakage of environmentally persistent organic pollutants. Second, the traditional batch reactor production mode has poor temperature control accuracy and many side reactions, which not only leads to high residual volatile fluorides in the product, but also releases a large amount of unorganized fluorine-containing waste gas during the production process, causing potential impacts on the production environment and surrounding ecology. Third, the industry generally lacked a fluorine element closed-loop recycling mechanism in the past. Most of the fluorine-containing residual liquid generated during the production process was disposed of as hazardous waste, which not only caused serious waste of fluorine resources, but also brought huge environmental pressure. With the continuous upgrading of global environmental control requirements for fluorine-containing chemicals, the latest EU PFAS restriction regulations have directly excluded fluorosilicone oil produced by traditional processes from the compliant market. The green transformation of China's fluorosilicone oil industry has become a necessary survival and development task.
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 fluorination reaction technology. The millisecond-level precise temperature control of the microchannel reactor increases the atomic utilization rate of the fluorination reaction to 97%, and the equipment utilization rate jumps from 38% of the traditional batch process to 94%. The production energy consumption per unit product directly decreases by 42%, and the unorganized fluorine-containing waste gas emission caused by material leakage in the traditional fluorination reaction process is completely eliminated. The fluoride concentration in the production environment is far lower than the national occupational safety standard limit. Second, the full construction of the closed-loop fluorine resource recycling system. The fluorine element recycling process promoted in the industry adopts membrane separation + catalytic cracking technology to re-convert the fluorine-containing by-products generated during the production process into fluorination raw materials for recycling. The comprehensive utilization rate of fluorine resources is increased to 99.2%, and the generation of fluorine-containing hazardous waste is reduced by 93% compared with that before the transformation, completely solving the high-pollution pain point of fluorosilicone oil production from the source. Third, the full application of low-VOC residue-free post-treatment process. The green supercritical fluorocarbon extraction technology is used to replace the traditional organic solvent cleaning process. The residual amount of volatile organic compounds in the final fluorosilicone oil product is less than 5mg/kg, fully meeting the latest EU PFAS environmental control requirements. The full life cycle carbon footprint of the product is 61% lower than that of products produced by traditional processes.
The low-VOC fluorosilicone oil produced by green processes has achieved large-scale applications in multiple high-value-added new energy scenarios. In the field of power batteries, the lithium battery separator coating prepared with this green fluorosilicone oil has a surface energy as low as 8mN/m, and the contact angle of the electrolyte on the separator surface exceeds 120°, completely eliminating the electrolyte leakage problem of lithium batteries during high-rate charge and discharge. At the same time, the thermal stability of the coating is greatly improved, the shutdown temperature of the separator is increased from 130°C to 180°C, and the thermal safety performance of lithium batteries is improved by 45%. Related products have been batch supplied to the supply chains of leading global power battery enterprises. In the field of intelligent vehicles, the nano anti-fouling coating for automobile bodies prepared with this green fluorosilicone oil has the highest level 10 of water and oil repellency. The dust adhesion on the car body surface is reduced by 75%, and the car washing cycle of the vehicle is extended from the traditional 15 days to 90 days. The water consumption for car washing throughout the life cycle is reduced by 80%, and the weather resistance of the coating reaches more than 15 years, fully adapting to the low maintenance requirements of intelligent vehicle users for body care. In the field of photovoltaic glass, this green fluorosilicone oil is used as a modified component of the anti-reflection and anti-fouling coating for photovoltaic glass, which can reduce the surface reflectivity of photovoltaic glass to 1.8%. At the same time, the self-cleaning property of the surface reduces the dust accumulation rate of photovoltaic modules by 68%. Outdoor actual measurements in high dust areas in northwest China show that the annual power generation of photovoltaic modules is increased by 8.7%, greatly increasing the power generation revenue throughout the life cycle.
The latest forecast released by industry associations shows that with the full maturity of the green manufacturing system, the domestic fluorosilicone oil market will maintain an average annual compound growth rate of 15.3% from 2026 to 2031, and the overall market size will exceed 13 billion yuan by 2031. The proportion of high value-added products produced by green low-VOC processes will increase from the current 28% to 72%. Relying on the cost and compliance advantages brought by green processes, the global market competitiveness of domestically produced fluorosilicone oil has been greatly improved. In the first half of 2026, the product export volume increased by 136% year-on-year, successfully entering the markets with the strictest control of fluorine-containing chemicals such as the European Union and North America, rapidly growing from a traditional exporter of mid-to-low-end fluorosilicone products to a core supplier of global green fluorine-containing functional materials.
