What EP Additives Do in Heavy-Duty Lubricants

EP additives form a protective film of phosphate or sulfide on the metal surface, preventing direct metal contact during gear meshing and reducing the coefficient of friction. At extreme temperatures above 500℃, EP additives form high-melting-point iron sulfide films through chemical reactions, preventing bearings from failing due to high-temperature adhesion.

Extend the lifespan of oil products: Prevent lubricants from failing under harsh conditions and reduce equipment maintenance costs.

Enhance load capacity: Suitable for heavy-load scenarios such as gear oil and industrial lubricating oil, ensuring the stable operation of equipment.

Compatibility upgrade: Synergistic with traditional anti-wear agents (AW), compatible with mineral oil, synthetic oil and bio-based lubricants.
