1. Lubrication Performance Beyond Physical Limits
Fluorosilicone oil, modified with fluorine atoms in its siloxane structure, maintains fluidity and lubricity at temperatures as low as -50°C (viscosity change <5%) and maintains molecular stability at temperatures as high as 200°C (thermal weight loss ≤ 0.3%/h). This wide temperature range stems from its unique helical molecular structure: at low temperatures, intermolecular forces weaken, preventing solidification. At high temperatures, the Si-O bond energy (452 kJ/mol) and the C-F bond energy (485 kJ/mol) synergistically resist thermal cracking.

II. Core Applications in Harsh Operating Conditions
Automotive Industry
Turbocharger Bearing Lubrication: Continuously Withstands 180°C High Temperatures and 30,000 rpm
Electric Vehicle Battery Cooling Systems: Ensures Flexible Pump and Valve Opening and Closing in Extremely Cold -40°C

Vacuum Technology
Semiconductor Coating Equipment: Maintains Low Volatility (Vapor Pressure <10⁻⁸Pa) at 10⁻⁶Pa Vacuum
Spacecraft Moving Parts: Passes NASA MSFC-272C Standard Space Environment Testing

III. Irreplaceable Technical Advantages
Compared to mineral oil/PAO synthetic oils, fluorosilicone oils offer three key advantages:
Chemical Inertness: Resistant to Strong Acids (98% H₂SO₄) and Strong Oxidants (30% H₂O₂)
Material Compatibility: Expansion Rate with NBR/FKM <1.5%
Long-Term Performance: 8 Years Maintenance-Free in Wind Turbine Pitch Control Systems
