What is an extreme high temperature grease?                                           

Standard industrial greases based on hydrocarbon technology can readily degrade when exposed to high temperatures (~ 240 C). In order to ensure the performance characteristics of greases to release oil under high pressure and reabsorb it when the stress is removed, it is often necessary to use specialized basestock technology for extremely high temperatures.

Considering the lubrication properties of a grease is critical when exposing a grease to high temperatures or pressures in an application. For those very extreme operating temperatures, consider a high temperature stability grease such as Mobil SHC PF 462.
