RAVENOL Mehrzweckfett mit Graphit is a lithium saponified multipurpose grease with finely divided graphite to increase heavy loads at very high temperatures.
RAVENOL Mehrzweckfett mit Graphit is formulated with a highly refined base oil mixture which contains less than 3% polycyclic aromatics.Through the graphite at high temperatures a lubrication film on the metals is formed, and the graphite takes lubrication to achieve optimal results.
The optimized formulation of RAVENOL Mehrzweckfett mit Graphit can also capture temperature peaks in the application.
Application Note
RAVENOL Mehrzweckfett mit Graphit has been designed for applications exposed to high temperatures and shock loads.
RAVENOL Mehrzweckfett mit Graphit is used in oven conveyor belts, pistons in hydraulic pumps and all types of bearings that run at low speeds.
RAVENOL Mehrzweckfett mit Graphit is also used as a sealant in high temperature gaskets from steam pipes and other hot pipe connections.
Characteristics
- Extreme shear stability
- Excellent corrosion protection
- Very good mechanical and chemical stability
- Very good aging resistant
- Good pump output also at low temperatures
