Krytox XHT-SX

Krytox XHT-SX is a high performance PFPE-based grease for applications with extremely high temperatures, up to 300°C (572°F). Krytox™ XHT-SX does not contain additional performance additives and is completely inert, making the XHT-S an ideal lubricant when there is a potential for chemical-lubricant interaction between process steps.

Krytox™ XHT-SX provides incredibly durable performance in extreme environments where traditional lubricants would degrade or entirely evaporate.

The Krytox XHT-SX grease is an extension of the Krytox GPL 240 series and Krytox GPL 20X series, but are designed to give higher performance in the 204–302 °C (400–575 °F) range. Krytox™ XHT-S series 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 XHT-SX grease contains no additives, so they are used when a potential for interaction between process chemicals and grease additives exists.

Krytox grease is made to a standard NLGI grade 2. PTFE is the standard thickener.

Applications for these lubricants are generally of a critical nature, such as when temperatures reach extremes that conventional lubricants cannot handle. Krytox™ XHT-S and XHT-SX greases are expected to be durable in highly aggressive environments. Where failure of components is not an option, because of durability, warranty, safety, loss of productivity, or downtime, Krytox™ lubricants are the ideal choice in a wide range of industries and applications.
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 lubricants.
