High Temperature Grease
Mobil SHC Grease 462 PF is formulated with perfluoropolyether (PFPE) that is thickened with polytetrafluoroethylene (PTFE). Mobil SHC Grease 462 PF is a long-life, severe-service grease for bearings, valves, seals and other applications that require oxidation stability and lubrication performance at very high temperatures. Mobil SHC Grease 462 PF is also suitable for the lubrication of food processing equipment where NSF H1 registration is required for addressing cases of incidental contact with food.
Features and Benefits
Advantages and Potential Benefits
Excellent lubricity, corrosion protection and resistance to water
• Long life protection
Superb high temperature oxidative stability
• Mobil SHC Grease 462 PF is non-flammable, presents very low volatility and is highly resistant to degradation at temperatures up to 240˚C (464˚F).
• Reliable performance at high temperatures. The high-temperature stability provides bottom line savings from improved reliability and reduction in grease usage and manpower through extended re-lubrication intervals.
NSF H1 registration No. 157056, Kosher & Parve approval, Hallal approval
Suitable for applications in food processing and packaging where incidental contact with food is a risk, and in Kosher and Halal food preparation for multi faith applications.
• Resistance* to chemicals, caustics and solvents, including hydrocarbon oils, alcohols, acids, and caustic substances.
Note *: Testing should be conducted to verify resistance before use in intended service. Not intended for pressurized oxygen service without testing and validation by the equipment builder and intended operator.
Mobil SHC Grease 462 PF is engineered to provide excellent performance for a wide variety of demanding high-temperature applications including those found in packaging, corrugated paper, textile, steel, aluminum rolling, glass, chemical, automotive, aerospace, forestry and food industries.
Mobil SHC Grease 462 PF is recommended for corrugated paper plants for single-facer bearings and pre-heater bearings in heated rolls sections and other bearings.
Mobil SHC Grease 462 PF should not be used when mixed with other mineral or synthetic greases unless of similar composition.
Mobil SHC Grease 462 PF is registered to the requirements of NSF H1 for incidental food contact which means a limitation of 10ppm grease in food product per FDA 21CFR 178.3570. It is not to be used as a direct food contact lubricant.
