Fluorosilicone oil, with its unique molecular structure (siloxane main chain combined with fluorine-containing side chains), exhibits excellent chemical stability, oil resistance, and low surface tension in highly corrosive environments. It can be used as a base oil or directly in the preparation of special lubricants, effectively solving equipment lubrication problems in strong acid, strong alkali, organic solvent, and high-temperature oxidation environments.
I. Core Advantages of Fluorosilicone Oil in Highly Corrosive Environments
Breakthrough in Chemical Stability
The C-F bond energy in fluorosilicone oil molecules is as high as 485 kJ/mol, far higher than the C-H bond (413 kJ/mol), giving it extremely strong resistance to strong oxidizers, strong acids and bases, and organic solvents.
In chlorine-containing environments (such as the chlor-alkali industry), glass wool impregnated with fluorosilicone oil can extend equipment service life by more than 5 years, far exceeding ordinary silicone oil.
It remains stable against strong oxidizing media such as liquid oxygen, hydrogen peroxide, and fuming nitric acid, making it suitable for aerospace and special chemical fields.

Wide Temperature Range Adaptability
The operating temperature range is -60℃ to 250℃, maintaining viscosity stability even at extreme temperatures, suitable for polar equipment, high-temperature reactors, and other applications.
The volatilization rate at high temperatures (200℃) is less than 0.05%, far lower than ordinary mineral oil, ensuring long-term lubrication.
Optimized Interfacial Performance
The surface tension is as low as 20-24 mN/m (ordinary silicone oil is 21-25 mN/m), allowing it to form a uniform lubricating film on metal surfaces, reducing the steel-steel boundary friction coefficient by 30%-50%.
Its low refractive index (1.37-1.40) makes it suitable for the lubrication of optical equipment and precision instruments.

II. Specific Solutions in Highly Corrosive Environments
Preparation of Special Lubricants
Fluorinated silicone grease: Using polytetrafluoroethylene (PTFE) to thicken perfluoropolyether oil, with the addition of anti-corrosion additives, suitable for environments from -40℃ to 270℃. Typical Applications: Semiconductor cleanroom equipment bearings, automotive windshield wiper motor bearings, high-temperature valves and plastic gears
Advantages: Compatible with most rubbers/plastics, resistant to water, oil, organic solvents, and strong acids and bases.
Fluorosilicone Grease: Thickened with trifluoropropyl silicone oil, suitable for temperatures from -40℃ to 240℃, especially suitable for the watch industry and micro-mechanical systems.

Used directly as a lubricating base oil
Perfluorosilicone Oil: Can be used alone or mixed with dimethyl silicone oil. Its lubricity is significantly better than chlorinated phenyl silicone oil, and even superior to mineral oil-based greases under high loads.
Methylfluorosilicone Oil: Viscosity range 300-1000 mPa·s (25℃), operating temperature -40～204℃, especially suitable for high-speed, heavy-load bearings in contact with chemical reagents.
Application Examples: Used in film stretching and tentering machine bearings, heat setting machine conveyor belt bearings, high-temperature paint oven chain bearings, etc.

Surface Treatment and Protection
Molecular Assembly Film Technology: Fluorosilicone oil forms a molecular film on the substrate surface through chemical adsorption, with an outer chemical composition of -CF₃, exhibiting extremely high hydrophobicity and oleophobicity, significantly reducing the surface friction coefficient.
Fabric/Leather Waterproofing and Stain Resistance: Alkyl chains containing 8-10 perfluorocarbon atoms achieve optimal waterproofing and oil repellency, increasing the contact angle to over 110°.
Metal Surface Protection: Used in demisters in the chlor-alkali industry, providing corrosion resistance to chlorine gas for over 5 years.
