Chemical Stability

TorrLube® will not react with chemicals and other lubricants or cause them to degrade. Because of the inert nature of the TorrLube®, it will not mix well with these and could separate because of its higher density. TorrLube® oils and greases are completely insoluble in water.

TorrLube® PFPE oils are essentially inert to most chemicals. No reaction is observed with boiling sulfuric acid, fluorine gas at 200°C, molten sodium hydroxide, chlorine trifluoride at 10-50°C , uranium hexafluoride gas at 50°C, or any of the following materials at room temperature: JP-4 turbine fuel, unsymmetrical dimethyl hydrazine, hydrazine, diethylenetriamine, ethyl alcohol, aniline, 90% hydrogen peroxide, red fuming nitric acid or nitrogen tetroxide. TorrLube® oils are slightly soluble in hydrazine and have moderate (25 to 30 percent) solubility in nitrogen tetroxide.

TorrLube® oils are not soluble in common organic solvents, acids and bases, but some solvents will dissolve PFPE oils. TorrLube oils are completely miscible in highly fluorinated solvents such as trichlorotrifluoroethane (Freon 113), hexafluorobenzene, 2,3-dihydrodecafluoropentane (Vertrel®), perfluorooctane, perfluorohexane, perfluorodimethylcyclobutane isomers, and 1,1 dichloro-1-Fluoroethane. PFPE’s are freely soluble in supercritical CO2.
TorrLube is safe for use with rubber, elastomers, plastics and metals commonly used as seals and bearings.

A type of chemical known as a Lewis acid (electron pair acceptor) can have reactivity with PFPE oils and will limit the temperature that they can be used at. Typical Lewis acids are boron trifluoride, aluminum chloride, iron(III) chloride, and titanium tetrachloride. At elevated temperatures these materials can lead to decomposition of any PFPE.

Caution should be taken with metallic alkalai such as sodium and lithium metals as reactions could occur readily.

Fluorinated solvents and refrigerant gases can dissolve PFPE oils and affect their performance in use. They will not react but the oils will be carried away from the lubricating point.

Some grease grades contain additives for anti-corrosion or extreme pressure and these additives do not have the same chemical stability as the oils and thickeners. In chemical contact applications it is typically common to use greases without additives.

TorrLube performance lubricants are not only resistant to oxygen and reactive gases but are inert to virtually all chemicals commonly used in most industries.
TorrLube® has also been tested and used in the presence of gaseous and liquid oxygen and chlorine with no reactivity noted
