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.
Estimated Useful Range °C: –20 to 300 Base Oil Viscosity, cSt @40°C: 500 Oil Viscosity Index: 149 Oil Pour Point °C: -25 Maximum Volatility in 22 hr, % @204 °C: <1 Appearance: White, creamy consistency Specific Gravity at 0°C: 1.99 Food Contact Approval: NSF H-1
Primary Chemistry: PFPE
Features & Benefits
Krytox™ XHT-AC grease provides extended lubrication intervals and longer equipment life.
Krytox™ XHT-AC series grease contains sodium nitrite to offer anti-corrosion performance.
The base oil is an extremely viscous oil that provides good viscosity and lower evaporation at high temperatures.
Krytox™ XHT-AC series grease is nonflammable, oxygen-compatible, and chemically inert.
• Paint plant conveyor bearings • Corrugator and paper machine bearings • Aluminum can manufacturing bearings • Welding machines • High temperature fans • Textile equipment • Tenter frames • High temperature ovens • Conveyor systems in glass and aluminum plants • Textile calender roll bearings • Brick kiln car bearings • Valve lubrication • Ventilation fan bearing grease • Rod mills
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.
