KRYTOX 143AZ/AA/AY/AB/AC/AD

chemours™krytox® 143 series oils are clear, colorless,fluorinated synthetic oils that arenonreactive, nonflammable, safe in chemical and oxygenservice, and are long-lasting. krytox® is a perfluoropolyether(pfpe)—also called perfluoroalkylether (pfae) orperfluoropolyalkylether (pfpae)   the polymer chain iscompletely saturated and contains only carbon, oxygen, andfluorine. on a weight basis, a typical krytox® oilcontains 21.6% carbon, 9.4% oxygen, and 69.0% fluorine.

all standard grades of grease are thickened with highefficiency ptfe, whose formula is (cf2-cf2)n. this specialhigh efficiency thickener has a melting point of 325°c (617°f)and has low molecular weight and submicron (0.2 μ) particlesize for higher performancein bearings.

krytox® 240 series greases are white buttery greases with allof the same properties as our 143 series oils thatthey are made from, but they are in greaseform. 

krytox® 250 series ep greases are black greases thatcontain molybdenum disulfide added as an extremepressure additive for highly loaded gears andbearings. 

krytox® 283 series anticorrosion greases are white greasesthat contain sodium nitrite. these grades providerust protection at ambient temperatures, corrosion protection athigh temperatures, andantiwear protection.

chemours™ krytox® 240 ac, 240 ab and 240 az gr-1greases now have nsf approval for incidental foodcontact (h-1) in andaround food processing areas.
