Krytox HXT-ACX

Krytox™ XHT-ACX – High Temperature Grease

Krytox™ XHT-ACX Grease is a special high-temperature grease with low oil evaporation that provides protection against wear and oxidation and is compatible with all elastomers and plastics.

Krytox™ XHT-ACX – High Temperature Grease

Krytox™ XHT-ACX has excellent lubrication over a wide temperature range but is designed to perform best at temperatures above 200°C (400°F). The greases in this Krytox™ XHT ACX series are non-flammable, oxygen compatible and chemically inert.

Krytox™ XHT-ACX series greases are an extension of the Krytox™ 240 and Krytox™ GPL 22X series, but are designed to perform best in the 204–302°C (400–575°F) range. Krytox™ XHT-AC contains sodium nitrite to provide anti-corrosion performance. These greases should be used at temperatures below 320°C (608°F), where the polytetrafluoroethylene (PTFE) thickener could begin to melt.
