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 relubrication.
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-CF2
CF3
| 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.
