Complex or polyurea greases intended for extreme operating environments will feature dropping points clearing 230 °C to 250 °C. 🌍 International Equivalents

Formulated under GOST 1033-79, these are intended for low-temperature applications up to about 65 °C. Their dropping points typically register on the lower end, around 75 °C to 100 °C. gost 6793

Technicians monitor the cup. The exact temperature recorded on the thermometer when the first drop falls through the bottom hole is officially cataloged as the dropping point. Complex or polyurea greases intended for extreme operating

Lubricating greases are engineered by combining a base oil with a thickener and performance additives. The thickener holds the oil like a sponge. As grease is heated, it reaches a temperature where the thickener can no longer retain the oil. Technicians monitor the cup

The dropping point is a critical physical indicator in tribology (the study of friction and wear). It indicates the specific temperature at which a grease passes from a semi-solid to a liquid state under controlled conditions. 🔍 What is the Dropping Point?
