High Performance Lubricants For Demanding Operating Environments
Chemours Krytox® oils and greases increase the service life of critical components, allowing equipment manufacturers to extend warranties and manufacturing plants to reduce costly maintenance, while improving productivity by reducing component failure. They can be a significant contributor to lowering the cost of doing business.
Krytox® from Chemours™ is a high-performance, non-flammable and chemically inert lubricant that is compatible with oxygen and has a strong resistance to aggressive chemicals. It can be used from temperatures of -95° C (-139°F) up to 343°C (650°F) or higher with relubrication, depending on the grade.
Krytox® oil is a perfluorinated polyether. It is a liquid fluoropolymer, similar to liquid Teflon®. Greases are made with various viscosity grades of PFPE oil that are thickened with special PTFE grease thickeners to match the performance capabilities of the oils. Various additives for corrosion protection, extreme pressure conditions, or antiwear improvement are added to some of the grades.
DuPont™ Krytox® NRT oils and greases are designed specifically for critical oxygen service equipment where failure is not an option.
- Non-flammable — Krytox™ XHT will not burn or support combustion, even in 100% liquid or gaseous oxygen — providing high-temperature stability up to 399 °C (762 °F)
- Longer component use-life, less downtime and less frequent re-lubrication
- No oxidation and low volatility
- Undamaged by — and non-reactive with — acidic or caustic cleaners and disinfectants, steam, moisture and high temperatures
- Insoluble in most solvents — but soluble in highly fluorinated fluids and some supercritical fluids such as CO2
- Ideal for all components, including bearings, seals, valves, O-rings, chains, gearboxes and agitators
- Minimal environmental footprint
- Chemically and biologically inert and silicone-free
- Safe for use around oxygen, and non-reactive with chemicals typically used in industrial applications
- Contain no volatile organic compound (VOC) materials or chlorine
