The Krytox NRT 8906 series of Krytox oils and greases deliver nonreactive, nonflammable, 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.

Greases in the Krytox NRT 8906 series have been specially formulated for reactive gas service. With Krytox base oil, the NRT greases have special thickeners and additives for use with reactive gas or chemical applications.

The superior film-forming capability of Krytox lubricants provide 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 failure. Krytox oils and greases are perfluoropolyether (PFPE) lubricants—also called perfluoroalkylether (PFAE) or perfluoropolyalkylether (PFPAE). Many of the NRT series of Krytox 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), low molecular weight, and submicron (0.2 μm) particle size.

All Krytox NRT oils and greases have been tested by West German Federal Institute for Materials Testing (BAM). All NRT oils and greases have been tested by West German Federal Institute for Materials Testing (BAM). Chemours lubricants have been used in oxygen and reactive gas service for decades. Krytox lubricants have been independently tested by organizations, including BOC, Air Liquide, NASA, General Dynamics, and Praxair, and proven acceptable for oxygen and other reactive chemical compatibility.

Krytox NRT 8906 provide excellent lubrication options for valves, regulators, seals, and pump and motor bearings at a wide range of operating conditions.
