Improvement of Tribotechnical Properties of Polyurea Greases in Various Dispersion Media with Different Fillers
The properties of lubricating grease fillers such as molybdenum disulfide, tungsten disulfide and graphite are described. Their influence on the tribotechnical properties of polyurea greases prepared with various dipersion media studied using a Brugger tribometer in accordance with DIN 513471:20000; an SRV-3 tribometer, in accordance with ASTM D5707.
