Extreme Pressure Antiwear Additive
Extreme Pressure Antiwear Additive
Extreme pressure (EP) additives in lubricants are critical additives that prevent metal wear and sintering by forming chemical reaction films to separate metal surfaces. Key functions include:
- Extreme Pressure Protection: Enhanced load-carrying capacity
- Anti-Micropitting: Reduced surface roughness
- Thermal Stability: Instantaneous high-temperature resistance
- Synergistic Lubrication: Forms complementary protective layers when combined with sulfur-phosphorus anti-wear additives
