Krytox™ 240AD Aerospace Grease. High molecular weight base oil without additives.
Krytox™ 240AD white buttery greases with all of the same properties as the 143 series oils that they are made from, but they are in grease form. The properties that they are clear, colorless, fluorinated synthetic oils that are nonreactive, nonflammable, safe in chemical and oxygen service, and are long-lasting.
Krytox® 240AD is mainly used for aerospace applications with higher temperatures, requiring a heavier molecular weight highest viscosity base oil.
Krytox™ 240AD Aerospace Grease is used the higher temperature AAND applications.

Krytox™ greases are nontoxic lubricants that maintain their lubricity and viscosity properties to reduce maintenance costs associated with re-lubrication, component failure, and downtime in demanding applications. They are created by thickening synthetic perfluoropolyether-based oil (PFPE) with polytetrafluoroethylene (PTFE) powder. The PTFE thickener forms a barrier that holds the base oil at friction contact points for long-term lubrication, without requiring complicated oil recirculation systems. Anit-corrosion, High Temperature and High Pressure additives are also provided for specialized applications.
