Krytox™ XHT-AC Grease
Krytox™ XHT-AC grease has an Oil Viscosity of 500 cSt at 40°C and the estimated useful temperature range is 250 to 320°C.
Krytox™ XHT-AC Grease | High Temperature Grease
Anti-Corrosion Additive for extreme corrosion protection
Krytox XHT AC grease is a special high temperature grease with low oil evaporation that provide anti-wear and rusting protection, and is compatible with all elastomers and plastics. These greases have excellent lubrication over a broad temperature range, but are designed to work best at temperatures over 200 °C (400°F). Krytox XHT AC grease is nonflammable, oxygen-compatible, and chemically inert. Krytox greases provide extended lubrication intervals and longer equipment life.
Krytox XHT AC greases are an extension of the Krytox 240 series and Krytox GPL 22X series, but are designed to give higher performance in the 204–302°C (400–575 °F) range. Krytox™ XHT-AC greases contain sodium nitrite to offer anti-corrosion performance. These greases should be used below 320 °C (608 °F), where the polytetrafluoroethylene (PTFE) thickener could begin to melt. The base oil is an extremely viscous oil that provides good viscosity and lower evaporation at high temperatures. Krytox grease is made to a standard NLGI grade 2. PTFE is the standard thickener. For additional Krytox lubrication series info, please see Krytox GPL 22X series or Krytox 240 series.
Krytox XHT AC compatibility with metals
Because of their low surface tensions, Krytox lubricants easily wet metallic surfaces. Krytox lubricants are chemically inert and, therefore, have no adverse effect on metals when the temperature is below 288 °C (550 °F). Above 288 °C (550 °F), many alloy steels, stainless steels, and other metals, such as aluminum alloy, titanium alloy, nickel alloy, and cobalt alloy, can be used with Krytox.
