Krytox Aerospace Grade Fluorinated Oils 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 polytetrafluoroethylene (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 sub-micron (0.2 m) particle size for higher performance in bearings.
