Krytox 250AZ

Krytox 250AZ grease is a black grease that contains molybdenum disulfide added as an extreme pressure additive for highly loaded gears and bearings.

Lowest viscosity in the 250 series with a viscosity of 24.7 cSt at 38°C and 4.2 cSt at 99°C. Temperature Range is -57-149°C.

Since the first commercial application over 50 years ago, Krytox synthetic lubricants have delivered consistent, superior, reliable and extended performance. Today, with new additives for new challenges, Krytox lubricants continue to deliver extreme performance under the most extreme conditions. Krytox 250AZ is the lubricant of choice for demanding conditions —high and low temperatures, extreme pressure, and harsh environments.

Krytox greases are used in a variety of limited-motion mount systems associated with aircraft engines, such as an oil tank mount bracket for a Trent 1000 engine.

Krytox lubricants can be used to improve the performance of traditionally non-lubricated materials, such as DuPont™ Vespel® CR-6100 bushings.

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.

All standard grades of grease are thickened with high-efficiency 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 μ) particle size for higher performance in bearings.
