About DuPont Krytox®

..
Krytox® Oils and Greases
offer a unique combination of properties that provide exceptional, yet cost-effective solutions to your most difficult problems. Compared to other lubricants, only Krytox oils and greases combine high-temperature performance, non-flammability, and chemical inertness under a variety of conditions. Krytox oils and greases increase the service life of critical components, allowing equipment manufacturers to extend warranties, and manufacturing plants to reduce costly maintenance and improve productivity due to component failure.

Krytox® Oils and Greases are exceptional lubricants that provide superior protection and load-carrying ability under the most severe conditions. They are especially suited for use in 100% liquid or gaseous oxygen services. Krytox oils and greases are effective at temperatures as hot as 750°F (399°C) and as cold as -60°F (-51°C). From the aggressive world of chemical processing, to the high temperatures in state-of-the art automotive applications, to the critical tolerances of aerospace mil specs, Krytox oils and greases are becoming the lubricants of choice worldwide.

Benefits of Krytox®
 

Attribute
Benefits
Application
Low vapor pressure Oil evaporates slowly, extending lubrication intervals Used as sealant or lubricant in vacuum systems, high-temperature bearing, valve or O-ring lubricant, oven conveyor chain and bearing grease, or any use that requires high-temperature stability, low vapor pressure, high vacuum, chemical inertness, or in industries that manufacture oxygen
Radiation stability No breakdown in properties up to 10E07 rads Nuclear, aerospace, and difficult-to-access areas for repair or replacement
Thermal and oxidative stability Reliable and consistent in low- or high-temperature conditions; non-reactive; does not break down All industries
Non-flammability Does not burn or support combustion even in 100% liquid or gaseous oxygen Oxygen service, aerospace, chemical, semi-conductor
Low-temperature environments Low viscosity oils used at temperatures as low as -57°C (-70°F) Aerospace
High-temperature environments Krytox® has dropping point (thickener melting point) of 325°C (-617°F). Special thickener formulations provide useful lubrication up to 371 to 399°C (700 to 750°F) or higher with relubrication Industrial bearings, corrugator and hot oven bearings, chains
Low outgassing Longer lubricant life, less contamination High vacuum, clean rooms
Extreme pressure (EP) Protects bearings and other components under high loads or slower speeds. Components run quieter and wear protection is extended Automotive bearings, industrial
Meets military specifications Accommodate rigid specifications for safety in oxygen and harsh chemical environments Aerospace and industrial applications: space shuttle, bearings, sealants, O-ring lubricant, oxygen systems
Mechanical stability Does not break down under mechanical stress and lose ability to hold oil All bearings
Conductivity Select additives combined with Krytox® improve electrical conductivity Where electrical conductivity is needed
Anticorrosion Additives combined with Krytox® to protect metallic surfaces from corrosion caused by moisture and oxygen; prevents rusting Any applications subject to harsh environments including exposure to extreme temperature ranges, frequent temperature cycling, moisture, or chemicals
Antiwear Provides high specific load-carrying capability and highest protection against wear Bearings used in all applications
