Description

Extreme-temperature grease on the basis of perfluorinated polyether oils (PFPE) for use in food processing technology at maximum loads and temperatures. Areas of application Grease lubrication of friction and rolling bearings in the high-temperature range Application, for example at tunnel kiln cars, baking, burn-in and drying furnaces, hot gas units, reaction vessels, boiler plants, roller and conveyor rollers in continuous furnaces, etc. Use at bearing points under influence of chemicals/fuel Advantages and benefits Maximum water and steam resistance Extraordinary resistance to chemicals, for example to solvents, for example benzene, benzol, acetone, trichloroethylene and against inorganic acids, such as sulphuric acid, hydrochloric acid and nitric acid as well as stearic acids, alcohols and halogens Excellent plastic and elastomer compatibility For long-term lubrication of lubrication points subjected to high pressure up to 300°C Broad range of applications above the temperature limits of other lubricating greases Reduced maintenance and lubricant costs due to possible lifetime lubrication NSF H1 registered MOSH/MOAH-free Technical specifications Operating temperature: -30 °C → +280 °C NLGI grade: 2 DN factor (dm x n): 300,000 mm/min Base oil viscosity (40 °C): 510 mm²/s Four-ball test rig (welding load): > 10,000 N
