Overview
Krytox™ XHT-SX is a high-performance perfluoropolyether (PFPE) based grease thickened with polytetrafluoroethylene (PTFE) thickeners for applications with extremely high temperatures, up to 300°C (572°F). This fluorinated synthetic oil does not contain additional performance additives and is completely inert, making Krytox™ XHT-SX an ideal lubricant where there is potential chemical–lubricant interaction between process steps.
Krytox™ XHT-SX provides incredibly durable performance in extreme environments where traditional high-temperature greases or lubricants would degrade or entirely evaporate.
