Krytox™ + Oxygen = Safety and Reliability

Product Information
Challenge

Solution

Reduce safety hazards due to oxygen volatility.

Krytox™ provides protection for oxygen systems.

Oxygen reacts with conventional lubrication technologies
involving mineral oil or synthetics and increases
the potential for explosion, fire, deterioration of thelubricant, and component failure. It also accelerates thedecomposition of hydrocarbon lubricants, rapidly formingtars and varnish. Furthermore, oxygen degrades additives
more rapidly; thereby, reducing the life of the lubricant
and requiring more frequent re-lubrication. Additionally,conventional lubricants are subject to oxidation, attackby harsh chemicals or solvents, and volatilization of thebase oil that lead to failure of the lubrication system andassociated hazards. Conventional lubricant properties areoften not adequate for critical systems where failure is
not an option.

Chemours continuously experiments with Krytox™
to expand the range of consumer applications. In
various studies over the years, Krytox™ was tested attemperatures greater than 482 °C (900 °F) in thepresence of oxygen and at pressures up to 35 bar withno ignition.

Use of non-compatible lubricants requires component
installation behind explosion-proof barriers. To avoid fireand explosion, flammable lubricants need to be kept
below their explosive limits by purging with nitrogen. While
this process can keep lubricants below the ignition point,
it is cumbersome, expensive, and relies on mechanicalequipment and interlocks that can fail. The process also
increases the risk of compression auto-ignition withstandard lubricants, if they are hit by a surge of oxygen.

Krytox™ fluoropolymer lubricants have been used in oxygen
service by NASA and the aerospace industry for over 35years, where it became vital to find materials that werenonflammable and would not interfere with infrared sensor
performance. Krytox™ was also tested and approved forsafe use in oxygen service by BOC, Air Liquide, West
German Federal Institute for Materials Testing (BAM),
Praxair, Air Products, NASA, General Dynamics, as well asnumerous other oxygen industry authorities. Furthermore,
Krytox™ was successfully used in Cryostar, Cryomec,Estritio, Cosmodyne, APD cryogenic pumps, cryogenic
blowers, bearings, connecting rods, oxygen bombs, valves,fittings, and O-rings.
Krytox™ oils are prevalent as vacuum pump fluids in oxygen
service.

Krytox™

Performance
The wide range of chemically inert Krytox lubricants
provides the best available lubrication for all oxygen
service equipment.
™

Krytox™ products provide excellent lubricity, leading toextended equipment life versus alternative technologies.
In addition to being non-reactive towards oxygen, Krytox™
products are also safe to use with other oxidizing
chemicals, such as chlorine. They are chemically inert,
thermally stable, nonflammable, and non-volatile. Thiswide line of products provides excellent lubrication at
both low and high temperature extremes, resulting inincreased applications in the automotive, electronics,paper, chemical, aviation, and aerospace industries.
Krytox™ lubricants will reduce the complexity of oxygen
systems and provide safe operation for all mechanicalcomponents. The 100% compatibility and nonflammability of Krytox™ may allow auxiliary systems
designed to prevent fire and explosion to be eliminated.
There are several grades of Krytox™ oil and grease to meet
every lubricating requirement of oxygen and compressedgas users. For example, soft Krytox™ greases with XP
are excellent for cryogenic applications that require
soft greases and anti-corrosion additives to prevent
skidding during start-up and corrosion resulting fromtemperature cycling. Krytox™ patented XP additive is thefirst robust, soluble, anti-wear/anti-corrosion additive
for fluoropolymer lubricants and provides excellent
protection for cryogenic applications. The XP additive
provides the best available anti-wear and anti-corrosion
prevention in an oxygen compatible lubricant.
