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.
