Dropping point: Dropping point is an
indicator of the heat resistance of grease. As grease
temperature rises, penetration increases until the grease
liquefies and the desired consistency is lost. Dropping
point is the temperature at which a grease becomes fluid
enough to drip. The dropping point indicates the upper
temperature limit at which a grease retains its structure,
not the maximum temperature at which a grease may be used. A
few greases have the ability to regain their original
structure after cooling down from the dropping point.
