Krytox™ GPL 407 Grease
Krytox™ GPL 407 grease has an Oil Viscosity of 440 cSt at 40°C and the estimated useful temperature range is –70–316 °C.
Krytox GPL 407 Grease | For Ultra-high Temperatures
Formulated using a non-melting thickener
Krytox GPL 407 grease from Chemours is made using a non-melting thickener, instead of the normal Krytox™ PTFE. This change from PTFE to silica boosts the temperature capability of the grease from approximately 316 °C (600 °F) to an upper limit determined by the evaporation/breakdown temperature of the oil. Krytox™ GPL-407 is made from Krytox™ GPL-107 oil, which, with proper ventilation, can withstand up to 399 °C (750 °F) and higher temperatures for brief periods. With replenishment/re-lubrication, it can last longer.nWhile Krytox™ GPL-407 is not meant to replace the Krytox™ GPL-200 series at temperatures below 288–316 °C (550–600 °F), it does extend the range for using fluorinated greases to beyond the 316 °C (600 °F) limit of PTFE and Teflon™ thickened greases. Krytox™ GPL 407 has higher oil separation than PTFE thickened greases and, therefore, might not last as long under equivalent conditions.
Why Krytox GPL 407 Grease?
Standard Krytox lubricants contain only carbon, oxygen, and fluorine; whereas, hydrocarbons contain hydrogen. The absence of hydrogen greatly increases the stability of the lubricants and renders them non-flammable with no flashpoint. They will not burn or support combustion, even in an environment of 100% liquid or gaseous oxygen. Krytox lubricants are not only resistant to oxygen but are also inert to virtually all chemicals used in a variety of industries. They are insoluble in most solvents but are soluble in highly fluorinated fluids and some supercritical fluids, such as CO2. At elevated temperatures and pressures, PFPE oils are highly resistant to attack by gaseous and liquid oxygen. As a result, Krytox oils and greases have become preferred lubricants in the oxygen manufacturing industry and in those industries that use oxygen.
