[vc_row 0=””][vc_column 0=””][vc_single_image image=”2475″ img_size=”large”][vc_column_text 0=””]Krytox™ 143 series oils are clear, colorless, fluorinated synthetic oils that are non-reactive, non-flammable, safe in chemical and oxygen service, and are long-lasting. Krytox™ is a perfluoropolyether (PFPE)—also called perfluoroalkylether (PFAE) or perfluoropolyalkylether (PFPAE)—with the following chemical structure:
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. All standard grades of grease are thickened with high-efficiency PTFE, whose formula is (CF2-CF2)n. This special high-efficiency thickener has a melting point of 325 °C (617 °F) and has low molecular weight and submicron (0.2 μ) particle size for higher performance in bearings.
Krytox™ 240 series greases are white buttery greases with all of the same properties as our 143 series oils that they are made from, but they are in grease form.
Krytox™ 250 series EP greases are black greases that contain molybdenum disulfide added as an extreme pressure additive for highly loaded gears and bearings.
Krytox™ 283 series anticorrosion greases are white greases that contain sodium nitrite. These grades provide rust protection at ambient temperatures, corrosion protection at high temperatures, and anti-wear protection.
Krytox™ 240 AC, 240 AB, and 240 AZ Grade 1 greases now have NSF approval for incidental food contact (H-1) in and around food processing areas. These three products meet the requirements of Mil Spec PRF 27617, Types 1, 2, and 3.
