DROPPING POINT
DROPPING POINTGENERALThe dropping point is the temperature at which the grease passes from a semisolid to a liquid state. This change in state is typical of greases containing soaps of conventional types added as thickeners. These tests are useful in identifying the types of greases and for establishing ...
