Chemours Krytox® 215 GPL Extreme Pressure Grease
Categories: Fluid; Lubricant; Perfluoropolyether (PFPE); PTFE Gellant

Material Notes: Krytox® GPL 210–217 EP greases are black greases that contain 5% molybdenum disulfide added as an extreme pressure additive for highly loaded gears and bearings. The grease additives may alter the chemical resistance of the grease. The standard grease consistency is NLGI grade 2 penetration (265–295). Softer or harder NLGI penetration grades can be made by special order. Special nonmelting silica thickeners are available for applications that are higher than the 325°C(617°F) melting point of the standard PTFE thickener.

These greases are based on Krytox® GPL 100–107 oils - 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.
