Chemours Krytox® 107 GPL Oil
Categories:	Fluid; Lubricant; Perfluoropolyether (PFPE)
Material Notes:	Krytox® GPL 100–107 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 perfluoro-alkylether (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. Chemours was formed from former DuPont performance chemicals businesses, including DuPont Performance Lubricants, in 2015.
