DuPont Krytox® XHT-750 Extreme High Temperature PFPE Oil
Subcategory: Fluid; Perfluoropolyether (PFPE)
Close Analogs: Information provided by DuPont Performance Lubricants.
Material Notes:
These oils are a special extreme high temperature grade with low oil evaporation and have had extra treatment to allow use at temperatures above the range of normal PFPE oils. It has excellent lubrication over a broad temperature range. Krytox® XHT series oils are nonflammable and chemically inert. Krytox® allows extended lubrication intervals and longer equipment life. The oil can begin to slowly degrade at temperatures above 330°C (625°F), and this will occur at an increasing rate as temperatures increase. Relubrication could be required at these temperatures to achieve optimum life. Krytox® PFPE oils are clear, colorless, fluorinated synthetic oils that are nonreactive, nonflammable, safe in chemical and oxygen service, and are long lasting. Krytox® is a perfluoropolyether (PFPE)— also called perfluoroalkylether (PFAE) or perfluoropolyalkylether PFPAE). The polymer chain is completely saturated and contains only carbon, oxygen, and fluorine. On a weight basis, a typical Krytox® oil contains 21.6% carbon, 9.4% oxygen, and 69.0% fluorine.
