    PFPE

    CHRISTO-LUBE® brand perfluoropolyether (PFPE) greases have established themselves as the lubricant of choice for use under moderate to severe conditions, both terrestrial and otherwise.  It is the Fluorine of the base stock and thickener that makes them so special.  Having said that, both backbones show similar and highly desirable properties;

    • Extremely wide operating temperature rangebearings-honeycomb-3311136-m.jpg
    • Superb thermal, chemical and solvent resistance
    • Nonflammable.
    • Extremely long life and stable over changing temperature and pressure ranges
    • Liquid and gaseous oxygen compatibility (BAM AND ASTM D-2512)
    • Low vapor pressure (up to 10-12 Torr - Low evaporation rate)
    • Wide operating temperature range (-90˚C - 290˚C)
    • Non–toxic behavior
    • Non–reactive with metal, plastic, elastomers and rubber
    • Good low and high temperatures wear properties
    • Clean room compatible

    Classic Applications include;
