Krytox Oils and Greases Properties Table (PFPE Oils and Greases)
Chemours Krytox Fluorinated Grease
The best combination of properties allows users to solve difficult lubrication problems at optimal costs.
Krytox greases also have excellent low and high temperature performance, allowing lubrication in the temperature range from -70℃ to 399℃.
Best properties in areas where excellent non-flammability, oxygen compatibility and chemical resistance to all chemicals are required, as well as guaranteeing excellent performance and longer service life as a lubricant, sealant and insulator.

Krytox grease and oil composition
Krytox fluorinated lubricants are perfluoropolyether (PFPE), also known as perfluoroalkylether (PFAE) or perfluoropolyalkylether.
Krytox® Fluorinated Lubricants are low molecular weight polymers consisting of hexafluoropropylene epoxide containing fluorine at the molecular terminus. The chemical structure of Krytox oil is as follows.
F-(CF-CF2-O)n-CF2CF3ㅡCF3 | where n = 10 to 60. The polymer chain is saturated and consists solely of carbon (C), oxygen (O), and fluorine (F) (without hydrogen (H)). The weight ratio of the components of a typical Krytox® oil is C (21.6 wt.%), O (9.4 wt.%), and F (69.0 wt.%).
