Overview
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 will not migrate in high-load environments.
Krytox™ 250AC is formulated with a synthetic perfluoropolyether (PFPE) base oil and a polytetrafluoroethylene (PTFE) thickener system that is completely inert and nonflammable, making it the ideal solution for applications where byproduct formation or flammability concerns are unacceptable.
