Industrial Technical Greases: EP, Calcium, Sodium — What's the Difference?

Grease isn't just thick lubricant: its composition (metallic soap, additives) determines its resistance to water, temperature and heavy loads. The wrong choice accelerates wear on bearings and linkages.

GREASE EP: for heavy loads

Extreme-pressure (EP) additives protect metal surfaces in contact under heavy load — industrial bearings, construction and mining equipment, where heavy loads cause rapid wear without proper protection.

CALCIUM GREASE: good water resistance

Calcium soap offers excellent resistance to water and washout, making it a good choice for equipment exposed to moisture or frequent washing.

SODIUM GREASE: for high temperatures

Sodium soap tolerates higher operating temperatures than calcium, but resists water less well — best reserved for dry, hot applications.

Frequently Asked Questions

In Short

Can two different greases be mixed?

Not recommended: incompatible soaps can degrade each other and lose their lubricating properties. Purge the old grease before switching type.

What packaging is available for industrial use?

CALCIUM GREASE is available in a 200g cartridge as well as a 14kg bucket for workshops and industrial sites.
