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.
