Introduction

Challenge

Krytox is the lubricant of choice for oxygen and reactive
gas service with over 40 years of experience.

Conventional mineral oil and synthetic lubricants are notcompatible with oxygen or other oxidizing chemicals.

Krytox™ oils and greases are completely nonflammable,chemically inert, thermally stable, and completely safe
to use in all areas of oxygen service. Our wide range ofproducts provide excellent lubricity at extremes of bothlow and high temperature. Krytox™ technology has set thestandard for lubrication in automotive, electronics, paper,chemical, aviation, aerospace, and other industries.

Oxygen will react with conventional lubrication
technologies, leading to potential for explosion, fire, anddeterioration of the lubricant and component failure.
Oxygen accelerates the decomposition of hydrocarbon
lubricants. They rapidly form tars and varnish, causing
bearings to fail. Oxygen will react with conventional
additives, leading to degradation, reduced lubricant life,
and a need for more frequent lubrication.

Krytox™ fluoropolymer lubricants have been used inoxygen service by NASA and the aerospace industry forover 40 years. Krytox™ has been used in cryogenic pumps
from the following manufacturers: Cryostar, Cryomec,
Estritio, Cosmodyne, and APD. Krytox™ has also been usedin cryogenic blowers, bearings, compressors, connecting
rods, oxygen bombs, valves, fittings, and O-rings, amongst
other mechanical components. Krytox™ oils are usedprevalently as vacuum pump fluids in oxygen service bymajor corporations such as BOC Edwards, Leybold, andEbara. The nonflammability and inertness to processing
chemicals provides safe performance and eliminatespotential explosive reactions.
Krytox™ has been tested and approved for safe use inoxygen service by BOC, Air Liquide, West German Federal
Institute for Materials Testing (BAM), Praxair, Air Products,NASA, and General Dynamics, amongst other oxygen
industry authorities.

The use of non-compatible lubricants requires
components be installed in explosion-proof barriers,
as well as the use of a nitrogen purge. To avoid fire andexplosion, flammable lubricants need to be kept below
their explosive limits by purging with nitrogen. This cankeep them below the ignition point; but, is cumbersomeand expensive, and relies on mechanical equipment andinterlocks that can fail. Standard lubricants are also atrisk of compression auto-ignition, if contacted by a surgeof oxygen.
Conventional lubricants are subject to oxidation, attack byharsh chemical or solvents, flammability, and volatilizationof the base oil, leading to failure of the lubrication system
and associated hazards.
Conventional lubricant properties are often not adequate
for critical systems where failure is not an option.

Solution

Krytox™ patented XP additive is the first robust soluble
anti-wear/anti-corrosion additive for fluoropolymer
lubricants and provides excellent protection for cryogenicapplications. Krytox™ XP additive provides the best
available anti-wear and anti-corrosion prevention in anoxygen compatible lubricant. Krytox™ XP was named theNASA Tech Briefs product of the month in 1998. Soft
Krytox™ greases with XP are excellent for cryogenic oxygen
applications.

The wide range of chemically inert Krytox™ oils andgreases provide the best available lubrication for all
oxygen service equipment.
Krytox™ lubricants are 100% compatible with oxygenand completely nonflammable. Krytox™ products provide
excellent lubricity, leading to extended equipment life vs.
alternative technologies. In addition to being non-reactive
towards oxygen, they are also safe for use with otheroxidizing chemicals, such as fluorine, chlorine, bromine,HF, etc.
Krytox™ compatibility and nonflammability may allow for
the elimination of auxiliary systems designed to prevent
fire and explosion.
Grades of Krytox™ oil and grease are available to meet
every lubricating requirement for oxygen and compressedgas users.
Cryogenic applications require soft greases and anticorrosion additives to prevent skidding during start-up
and corrosion resulting from temperature cycling. TheKrytox™ has also been tested at temperatures greaterthan 482 °C (900 °F) in the presence of oxygen withno ignition and tested at pressures above 345 bar withno impact.
Summary
Krytox™ lubricants are ideal to improve the safety andreduce the complexity of your oxygen system.
