Fluorosilicone oil has expanded its application boundaries across industries, with functional upgrades in the medical and textile sectors


1. Medical field: The coating of minimally invasive devices enhances the safety of use
In the field of medical devices, new breakthroughs have been made in the application of fluorosilicone oil. In response to the problems of minimally invasive surgical instruments being prone to adhering to tissues and difficult to clean, the R&D team has developed a medical-grade fluorosilicone oil coating technology. This coating, through special molecular design, forms a uniform and dense protective film on the surface of the instrument, with a contact Angle of over 115°. It has excellent anti-biological adhesion performance and can reduce the risk of tissue adhesion during surgery. At the same time, the coating has excellent resistance to steam sterilization. After being sterilized by 134℃ high-pressure steam for 50 times, it still maintains its complete structure, does not fall off or degrade, effectively extending the service life and safety of the equipment. Currently, it has entered the clinical verification stage.


2. Textile field: Endow fabrics with high-end functional attributes
The application of fluorosilicone oil in the modification of textile fabrics has also made new progress. The new type of fluorosilicone oil finishing agent for textiles has solved the problem of "difficulty in balancing water and oil repellency with breathability" of traditional finishing agents through molecular structure optimization. The fabric treated with this finishing agent has a water repellency level of grade 5 in AATCC 22-2020 standard and an oil repellency level of grade 6 in AATCC 118-2022 standard. Meanwhile, its air permeability remains above 1200g/(m² · 24h). It is much higher than the 800g/(m² · 24h) of fabrics treated with traditional fluorine-containing finishing agents. In addition, this finishing agent also has antibacterial functions, with an inhibition rate of over 99% against Escherichia coli and Staphylococcus aureus. It is suitable for high-end outdoor clothing, medical protective fabrics and other scenarios.


3. Performance Optimization: Low-temperature curing is suitable for multiple scenario requirements
To meet the processing requirements of different fields, the R&D team has also optimized the curing characteristics of fluorosilicone oil. The new type of low-temperature curing fluorosilicone oil can be cured at 80-100℃, which is significantly lower than the curing temperature of over 150℃ for traditional products. This not only reduces energy consumption during processing but also avoids damage to heat-sensitive substrates such as medical polymer materials and thin textile fabrics caused by high temperatures. Meanwhile, the adhesion of the product after low-temperature curing is increased by 20%, and it is less likely to crack under external forces such as bending and stretching, thus broadening the application range of fluorosilicone oil on fragile substrates.


4. Market potential: The upgrading of consumption drives the growth of demand
With the upgrading of consumption and the development of high-end manufacturing industries, the demand for fluorosilicone oil in cross-border fields such as medical care and textiles has been continuously rising. Data shows that the domestic market size of medical fluorosilicone oil is expected to reach 980 million yuan in 2025, and the market size of fluorosilicone oil finishing agents for textiles will exceed 1.2 billion yuan. Industry analysts believe that in the future, as the demand for functionalization and customization increases, fluorosilicone oil will further penetrate into more niche fields. With its unique physical and chemical properties, it will become a key material support for promoting the product upgrading of downstream industries.
