What is the NLGI consistency of Krytox grease grades?
Greases are formed by mixing the base oil with a thickener to form a grease. Krytox greases use a special high-thickening efficiency, low molecular weight polytetrafluoroethylene (PTFE) with very small particle sizes as their thickener. This is one of the most thermally stable thickeners for high-temperature, long-term greases. The higher thickening efficiency of the special PTFE thickener allows Chemours to formulate grease to maximize oil content for improved grease performance.
Greases can be formulated with different viscosity oils to handle different temperatures and load conditions. High-viscosity oils can be used in greases for high temperatures or heavy loads or low-speed applications. Low-viscosity oils can be used in greases where low-temperature properties are important or speeds are higher. Lower amounts of thickener form softer or more fluid-like
greases. Higher solid levels form harder, stiffer greases.
Additives are often added to the grease to enhance anticorrosion protection, raise load-carrying ability or help reduce wear. Our standard grease grade is NLGI Grade 2; however, upon request we produce NLGI Grades 000 through 6.
