Krytox™ NRT greases and oils deliver nonreactive, non-flammable, long-lasting performance even under the demanding temperatures and pressures of reactive gas
service. Krytox™ NRT lubricants are compatible with oxygen and other reactive chemicals and are extremely resistant to water washout. Krytox™ NRT lubricants are also compatible with polymers used in seals, O-rings and valves.
Krytox™ NRT 8950 is an extreme high-temperature grease with low oil evaporation. The special non-melting high temperature thickener in Krytox™ NRT 8950 also provides extreme pressure properties and works as a solid lubricant if the base oil is depleted. The base oil provides good viscosity and lower evaporation at high temperatures. The grease is slightly tacky and will provide extra bonding to the surface. Krytox™ NRT 8950 received a rating of 180 bar at 60 °C in the BAM oxygen reactivity test.
The superior film-forming capability of Krytox™ provides a thick oil layer that reduces friction and wear, extending equipment life in severe duty applications. The non-oxidizing nature of the oils makes the greases last longer. The oils don’t gum up as they age, so they won’t harden the greases and cause catastrophic failures.
Krytox™ NRT greases are thickened with a unique polytetrafluoroethylene (PTFE) with the formula (CF2-CF2)n. This special high efficiency thickener has a melting point of 325 °C (617 °F) and has low molecular weight and submicron (0.2 m) particle size.
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.
