Chemours™ Krytox™ 250 Series Black Extreme Pressure Aerospace Grease

Krytox® 250 series EP greases are black greases which contain molybdenum disulfide added as an extreme pressure additive for highly loaded gears and bearings.

DuPont™ Krytox® heavy-duty greases are used for high loading or slow speeds. EP greases have high load-carrying capability and good lubrication characteristics under boundary and mixed friction conditions. In addition to the EP additive in Krytox® heavyduty greases, Krytox® oil provides adequate EP protection as an oil by itself, due to the viscosity build under load and its unique tribo-chemistry.

DuPont™ Krytox® greases are based on perfluoropolyether (PFPE) oils. These synthetic fluorinated lubricants are used in extreme conditions such as continuous high temperatures up to 300 °C (572 °F) and higher temperatures for shorter periods, depending on product grade limits. Chemically inert and safe for use around hazardous chemicals, these lubricants are nonflammable and are safe for use in oxygen service.

Krytox® oils and greases are silicone free and do not damage plastics or elastomers or cause corrosion to metals. They are commonly used as lubricants in aerospace, automotive, industrial and semiconductor applications as well as solving many other routine lubrication problems.

Krytox® greases are the original products that this military specification was written for and have been certified continuously since the specification was originally written. This is the latest data from the recertification that is required every five years. Krytox® greases are standard as NLGI Grade 2 penetration.
