Krytox™ Performance Lubricants for the Chemical Processing and Petrochemical Industry.

At Chemours, we know from first-hand experience that chemical and petrochemical industry systems require lubricants that help support operational safety. Krytox™ Performance Lubricants do just that, with a broad selection of specially formulated synthetic oils and greases that are nontoxic, non-reactive, non-flammable, noncorrosive and compatible with polymers used in seals, O-rings and valves.

Independently studied and tested by companies and organizations such as BOC, Air Liquide, BAM, NASA and General Dynamics, Krytox™ lubricants have been confirmed as compatible for use with oxygen and other reactive chemicals.

Krytox™ lubricants, including the NRT line of oils and greases, were developed using DuPont technology to satisfy the special needs of the chemical industry.  These first-quality synthetic, perfluoropolyether- (PFPE-) based lubricants deliver a long list of desirable characteristics, including:

  • Safe, non-reactive, non-flammable use with reactive chemicals
  • Effective lubrication extends equipment use-life and saves maintenance
  • Will not auto-ignite in oxygen at temperatures up to 482 ºC
    (900 ºF)
  • No ignition at pressures up to 350 bar
  • Compatible with seal, O-ring and valve polymers
  • Maintain lubricity and stable viscosity throughout a wide range of temperatures in highly corrosive environments
  • Chemically and biologically inert and silicone-free
  • Unaffected and non-reactive to acidic or caustic cleaners as well as disinfectants, steam, moisture and high temperatures
  • Used for lubricating valves, fans, pumps, agitators, reactors, centrifuges and other components
  • Minimal environmental footprint and compatible with chemicals commonly used in industry−contain no volatile organic compound (VOC) materials or chlorine

Krytox™ Performance Lubricants for Reactive Gas Applications.

There are no second chances when working with reactive gas equipment. Conventional lubricants containing mineral oils and some synthetic lubricants can react with oxygen or halogens such as chlorine, fluorine and bromine — and that can lead to a catastrophic incident. Your reactive gas applications require lubricants that help ensure your safety and Krytox™ NRT line of oils and greases can. With Krytox™ NRT you get:

  • Highly effective, safe, non-reactive, non-flammable lubricants designed especially for use with reactive gases
  • Effective sealing and lubrication for longer equipment life
  • No auto ignition at temperatures up to 482 ºC (900 ºF)  in oxygen
  • No ignition at pressures up to 350 bar
  • Compatibility with most seals and polymers

Krytox™ NRT Performance Lubricants have been independently use-tested for oxygen and other reactive chemical compatibility by BOC, Air Liquide, BAM, NASA and General Dynamics. Using Krytox™ helps assure the safety of your reactive gas service operations. Krytox™ Performance Lubricants are more than just safe — they are remarkably effective lubricants, providing outstanding performance for mechanical systems under harsh conditions.

Compressors, bearings, seals, actuators, valves and more — they all last longer, run more efficiently and require less maintenance, thanks to Krytox™ NRT. It’s your ideal choice for use in cryogenic and firefighting applications, life support systems and reactive gas service equipment.

While the potential for explosion, fire, deterioration of lubricants and equipment failure is always possible, Krytox™ NRT oils and greases can help you avoid issues like:

  • The need for nitrogen purging to keep non-compatible lubricants below explosive limits
  • Costly, cumbersome equipment with interlocks that can fail
  • Risk of compression auto-ignition when conventional lubricants make contact in an oxygen surge
  • Lubrication system failure from oxidation, harsh chemical or solvent attack; flammability and volatilization of the oil base of standard lubricants
  • Bearing failure due to tars and varnishes
  • Frequent re-lubrication

Krytox™ NRT oils and greases are designed specifically for safe, long-term use in critical oxygen service equipment. Chemours has taken over from DuPont, who started supplying perfluoropolyether- (PFPE) based, synthetic lubricants that meet the demanding needs of oxygen and reactive gas applications since the 1960s.
