KRYTOX™ NRT LUBRICANTS

Krytox™ NRT Series

Lubricants for Reactive Gas Services, Krytox™ NRT oils and greases have been specifically developed for reactive gas applications. The NRT series is a part of the Chemours™ family of Krytox™ offerings. Krytox™ Perfluoropolyether (PFPE) oils are based on poly(hexafluoropropylene oxide), the most thermally stable of all PFPE oils. These oils are inert in oxygen and cannot burn or support combustion.

Krytox™ oils are differentiated by viscosity or vapor pressure performance, but these factors do not affect the oxygen stability of the oil. The greases in the NRT series have been specially formulated for reactive gas service. With base oil, the NRT greases have special thickeners and additives for use with reactive gas or chemical applications. Several of the NRT greases are thickened with polytetrafluoroethylene (PTFE) thickener. Because oil and the PTFE thickener are fully fluorinated, they will not oxidize under extreme thermal conditions. The NRT series also includes greases containing inorganic thickeners, especially useful for high pressure oxygen applications.

All Krytox™ NRT oils and greases have been tested by West German Federal Institute for Materials Testing (BAM).

They 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.
