Krytox 250AC

Krytox 250AC is a black PFPE grease that contains solid molybdenum disulfide dispersed to provide exceptional extreme pressure performance in critical, highly loaded gears and bearings in the aerospace industry. Krytox 250AC provides a high viscosity base oil that won't migrate in high load environments.
It has a viscosity of 270 cSt at 38°C and 26 cSt at 99°C. Temperature range is -34 to 288°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 250AC 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.
