Krytox GPL 215 grease

Krytox GPL 215 grease contains molybdenum disulfide for extreme pressure (EP) conditions and should be used for slow speed or heavily loaded applications where there is no danger of the molybdenum disulfide additive reacting with chemicals or causing contamination. 

Krytox GPL 215 heavy-duty grease is used for high loading or slow speeds. EP greases have high load-carrying capability and good lubrication characteristics under boundary and mixed friction conditions. In addition to the EP additive in Krytox GPL 215 heavy-duty grease, Krytox oil provides adequate EP protection as an oil by itself, due to the viscosity build under load and its unique tribochemistry.

A common test for analyzing EP performance is the Timken EP method, ASTM D2509. The test is performed by applying pressure between a rotating steel cup and a steel block and simulates line contact conditions. Two conditions are observed; the OK Load is the highest load at which no seizing or welding occurs, and it also reflects the load-carrying capability of the lubricant
