I. 300-500mm²/s Medium-Low Viscosity Range
Precision Equipment Lubrication
Suitable for applications requiring ultra-low shear resistance, such as watch escapements and micromechanical bearings. Its viscosity decay rate can be controlled to less than 3% over long-term operation.
Medical Equipment Maintenance
For high-frequency moving parts such as orthopedic drills and laparoscopic joints, it enables zero-resistance operation and reduces the risk of intraoperative jamming.
Chemical Valve Seals
In environments exposed to strong solvents (such as ketones and esters), the electron shielding effect created by fluorine atoms effectively resists media corrosion.
II. 500-1000mm²/s Medium-High Viscosity Range
High-Temperature Lubrication
With a temperature range of -60°C to 250°C, it is suitable for use in wide temperature ranges, such as automotive fuel systems and aviation fuel tank seals. It exhibits low volatile loss at high temperatures. Vacuum Equipment Applications
Stable performance in high vacuum environments up to 10⁻⁸ Pa, such as in semiconductor wafer manufacturing equipment, reduces contamination of precision components by volatiles.
Composite Mold Release
When used as a release agent, its low surface tension (contact angle of 110°) can reduce the release force of carbon fiber products by 70%, extending mold life to 2,000 cycles
