Fluocon® PFPE Vacuum Pump Oils for High-Vacuum and Corrosive Applications
The Pinnacle of Vacuum Lubrication
Fluocon® PFPE Vacuum Pump Oils: High-Performance Lubrication for Extreme Vacuum Environments
Fluocon® PFPE Vacuum Pump Oils represent the ultimate hydrogen-free lubrication solution, offering ultra-low vapor pressure and exceptional thermal-oxidative stability for demanding high-vacuum applications. Specifically engineered for systems where conventional mineral or synthetic oils fail, Fluocon® L series lubricants are built on a robust linear Perfluoropolyether backbone. By eliminating hydrogen atoms, this advanced fluid achieves a level of chemical inertness that is unmatched in the industry. Whether you are managing corrosive gas flows in semiconductor etching or maintaining high-integrity vacuum seals in aerospace research, Fluocon® PFPE vacuum pump oil ensures zero carbonization, minimal outgassing, and an extended service life that significantly reduces your total cost of ownership.
Advanced Chemical Composition & Manufacturing
The superior performance of Fluocon® PFPE fluids begins at the molecular level. Unlike standard vacuum oils, our PFPE is a polymeric chain composed exclusively of Carbon, Fluorine, and Oxygen. This unique hydrogen-free architecture is achieved through a high-precision polymerization process, resulting in a fluid that does not react with Lewis acids or strong oxidizing agents. The manufacturing process ensures a tight molecular weight distribution (ranging from 1,850 to 4,300 AMU), providing consistent kinematic viscosity across various grades—from the lightweight L2-06 to the robust H4-40. This purity is critical for preventing the formation of acidic by-products and sludge, which are common causes of pump failure in aggressive chemical environments.
Multi-Dimensional Performance Advantages
Fluocon® PFPE Vacuum Pump Oils are defined by their ability to provide solutions where others provide compromises:
- Ultra-Low Vapor Pressure: With values as low as 5×107 torr at 25℃, our fluids enable the achievement of ultimate total pressure targets in high-vacuum systems.
- Inherent Non-Flammability: Featuring no flash or fire point, these oils provide an essential safety margin in oxygen-rich or high-heat environments.
- Superior Material Compatibility: Fluocon® is completely non-reactive with most metals, plastics, elastomers, and rubbers, ensuring the integrity of your O-rings and seals.
- Extreme Thermal Stability: Resistant to thermal breakdown even at continuous operating temperatures exceeding 200 ℃, preventing oil consumption and deposit formation.
- Radiation & Chemical Resistance: Ideal for nuclear and chemical processing industries where radiation stability and resistance to aqueous/non-aqueous solvents are mandatory.
