Krytox™ NRT 8906 Grease

Krytox™ 8906 NRT provides excellent lubrication options for valves, regulators, seals, and pump and motor bearings at a wide range of operating conditions. It has a viscosity of 240 cSt @ 40°C and is NLGI grade 2.




Product Overview

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.

Features & Benefits

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

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.
