Product Overview

Krytox™ XHT-AC grease is a special high
temperature greases with low oil evaporation that provides anti-wear and rusting protection, and are compatible with
all elastomers and plastics. 

Krytox™ XHT-AC grease has excellent lubrication over a broad temperature range, but is designed to work best at temperatures over 200°C (400 °F). 

The Krytox™ XHT-AC series grease is an extension of the Krytox™ 240 series and Krytox™ GPL 22X series, but designed to give higher performance in the 204–302°C (400–575°F) range.

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.
