PFAS-free environmentally friendly fluorosilicone oil has been put into mass production and is compliant with the new global export standards. 

1. Global control over fluorine-based chemicals tightens; traditional fluorosilicone oil faces export barriers
In recent years, many countries have introduced PFAS (perfluoroalkyl substances) control regulations. The trace residual of perfluorinated additives in traditional general-purpose fluorosilicone oil pose risks of seizure and return during cross-border shipments. Export enterprises of automobiles, precision equipment, and medical devices are facing a significant increase in compliance pressure regarding raw material requirements. The traditional modification approach can only reduce the residue but cannot completely eliminate the PFAS structure. This has long restricted the expansion of the domestic specialty fluorosilicone material market overseas. The industry urgently needs a new synthetic solution for fluorine-free additives. 

2. Molecular chain reconstruction modification technology is implemented, completely eliminating PFAS components
The R&D team reconfigured the copolymerization path of fluorosilicon monomers, abandoned the use of full-perfluoroalkyl auxiliary catalysts, replaced the long-chain PFAS structural units with short-chain fluorinated alkyl groups, and combined with an environmentally friendly solid catalytic system to complete the entire process of synthesis. The new product has been tested by authoritative institutions and no PFAS was detected. It has the same oil and acid-base resistance performance as traditional products in the wide temperature range of -40℃ to 250℃, and the thermal decomposition temperature remains above 330℃, solving the industry pain point of being unable to balance compliance and performance. 

3. Large-scale trial use in multiple downstream fields, effectively optimizing production costs
This environmentally friendly fluorosilicone oil has been put into batch testing in three scenarios: automotive engine sealing, industrial anti-corrosion coatings, and medical demolding. After being used in automotive sealing parts, the resistance to fuel swelling has increased by 40%; in medical plastic high-temperature molding, there is no carbon residue after high-temperature treatment, and the product scrap rate has decreased by 20%; the salt spray test duration of outdoor metal anti-corrosion coatings has exceeded 1500 hours. The domestic synthesis route for raw materials simplifies the purification process, and the comprehensive production cost is reduced by 25% compared to imported compliant products. 

4. Green fluorosilicone becomes the mainstream upgrade direction of the industry
Industry analysis indicates that fluorosilicone oil without PFAS will become the standard category of general-purpose fluorosilicone materials in the future. Subsequent research and development will promote the substitution of bio-based raw materials, the development of low-VOC water-based fluorosilicone oil formulas, and the simultaneous improvement of the full-category environmental certification system. Relying on compliance advantages, it will expand overseas orders in Europe, Asia and Southeast Asia, and promote the green and internationalized two-way upgrade of the fluorosilicone oil industry.
