DuPont Krytox® 205 GPL Standard Grade Grease

 

Subcategory: Fluid; Perfluoropolyether (PFPE); Lubricant

Close Analogs:

Information provided by DuPont Performance Lubricants.

Material Notes:
Krytox® GPL 200–207 greases are white buttery greases with all of the same properties as the GPL 100–107 oils that they are made from, but they are in grease form. 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. All standard grades of grease are thickened with Krytox® 2000 polytetrafluoroethylene (PTFE), whose formula is (CF2-CF2)n. This special high efficiency thickener has a melting point of 325°C (617°F) and has low molecular weight and submicron (0.2 m) particle size for higher performance in bearings.

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.
