DuPont™ Krytox® Benefits Guide

 

Benefits Attributes Application

Oil evaporates slowly, extending lubrication intervals

Low vapor
pressure

 

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

No breakdown in
properties up to
10E07 rads
Radiation
stability
   Nuclear, aerospace, and difficult-to-access areas for repair or replacement
Reliable and consistent in low- or high-temperature conditions; nonreactive; does not break downThermal and
oxidative
stability
 All industries
Does not burn or support combustion even in 100% liquid or gaseous oxygenNon-
flammability
 Oxygen service, aerospace, chemical, semi-conductor
Low viscosity oils used at temperatures as low as –57°C (–70°F)Low-
temperature
environments
 Aerospace
Krytox® has a 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
High-
temperature
environments
 Industrial bearings, corrugator and hot oven bearings, chains
Longer lubricant life,
less contamination
Low
outgassing
 High vacuum, clean rooms
Protects bearings and other components under
high loads or slower
speeds. Components
run quieter and wear
protection is extended
Extreme
pressure (EP)
 Automotive bearings, industrial
Accommodate rigid
specifications for safety in oxygen and harsh chemical environments
Meets military
specifications
 Aerospace and industrial
applications: space
shuttle, bearings,
sealants, o-ring lubricant,
oxygen systems
Does not break down
under mechanical stress and lose ability to hold oil

Select additives
combined with Krytox® improve electrical conductivity
Conductivity Where electrical
conductivity is needed
Additives combined
with Krytox® to protect metallic surfaces from
corrosion caused by
moisture and oxygen;
prevents rusting
Anticorrosion Any applications subject
to harsh environments
including exposure to
extreme temperature
ranges, frequent
temperature cycling,
moisture, or chemicals
Provides high specific
load-carrying capability and highest protection
against wear
