EP Additive Types at a Glance
| Additive Type | Typical Weld Point | Best For | Watch Out For |
|---|---|---|---|
| Sulfur-Phosphorus (S-P) | 250–315 kgf | Industrial gearboxes, standard crane duty | Can attack bronze/brass above 90°C sump temp |
| Sulfur-Phosphorus-Boron | 315–400+ kgf | Heavy-duty slew rings, high-load gearboxes | Higher cost, less widely stocked |
| MoS2 (Molybdenum Disulfide) | 250–280 kgf as supplement | Open gears, wire ropes, shock load applications | Can settle in low-viscosity carriers |
| Calcium Sulfonate Complex | 300–355 kgf | Marine, humid, or corrosive environments | Specialized supply, higher cost |
