What is Krytox made of?
Krytox fluorinated oils are a series of low molecular weight, fluorine end-capped, homopolymers of hexafluoropropylene epoxide with the following chemical structure:
| where n=10 to 60
The polymer chain is completely saturated and contains only the elements carbon, oxygen, and fluorine; hydrogen is not present. On a weight basis, typical Krytox oil contains 21.6% carbon,
9.4% oxygen, and 69.0% fluorine.
