DuPont? Krytox? oils and greases are based on perfluoropolyether (PFPE) oils. This series of synthetic fluorinated lubricants are used in extreme conditions such as continuous high temperatures up to 204 °C (400 °F) and will survive short term peak temperatures of up to 220 °C (429 °F). Chemically inert and safe for use around hazardous chemicals, these lubricants are nonflammable and are also safe for use in oxygen service. Krytox? oils and greases do not damage plastics or elastomers nor cause corrosion to metals. They are commonly used as lubricants in aerospace, automotive, industrial and semiconductor applications as well as in solving many other routine lubrication problems. In addition, they provide exceptionally long lifetimes in sealed-for-life bearings and extend relubrication intervals in bearings that require relubricatio

Krytox? GPL 105 oil is a clear colorless fluorinated synthetic oil that is nonreactive, nonflammable, safe in chemical and oxygen service, and is long lasting. Krytox? is a perfluoropolyether (PFPE)--also called perfluoroalkylether (PFAE) or perfluoropolyalkylether (PFPAE) with the following  chemical structure: F- (CF-CF2-O)n-CF2CF3        |       where n = 10–60       CF3   The polymer chain is completely saturated and contains only carbon, oxygen, and fluorine. On a weight basis, a typical Krytox? oil contains 21.6% carbon, 9.4% oxygen, and 69.0% fluorine.
