Chemours Krytox - White Aircraft Instrument, Fuel & Oxidizer Resistant Grease, 2 oz Tube | 240AZ20Z
Krytox? 240 series greases are white, buttery greases with all of the same properties as the 143 series oils that they are made from, but they are in grease form. The 240 AZ, 240 AB and 240 AC meet MIL-PRF-27617 general specifications. Many of the other 240 series products meet other specifications for individual applications.
DuPont? Krytox? greases are based on perfluoropolyether (PFPE) oils. These synthetic fluorinated lubricants are used in extreme conditions such as continuous high temperatures up to 300 ?C (572 ?F) and higher temperatures for shorter periods, depending on product grade limits. Chemically inert and safe for use around hazardous chemicals, these lubricants are nonflammable and are safe for use in oxygen service.
Krytox? oils and greases are silicone free and do not damage plastics or elastomers or cause corrosion to metals. They are commonly used as lubricants in aerospace, automotive, industrial and semiconductor applications as well as solving many other routine lubrication problems.
Krytox? greases are the original products that this military specification was written for and have been certified continuously since the specification was originally written. This is the latest data from the recertification that is required every five years. Krytox? greases are standard as NLGI Grade 2 penetration.
