Chlorinated Paraffin Extreme Pressure Additive for Metalworking
Chlorinated paraffins (CPs) are among the most effective extreme pressure additives for heavy-duty metalworking operations including deep drawing, tapping, and gear hobbing, where contact pressures exceed the capability of sulfur and phosphorus-based EP additives alone. The chlorine content reacts with iron under tribological stress to form iron chloride low-shear films. Available in short, medium, and long chain lengths with 40–70% chlorine content, they are widely used in neat cutting oils and metalforming lubricants worldwide.

| 4-ball weld load | >400 kgf (high-chlorine grades) |
| chlorine content | 40–70 wt% (grade dependent) |
| flash point (COC) | >200 °C |
| kinematic viscosity (40°C) | 100–20,000 mm²/s |
Applications
- Neat cutting oils for heavy-duty tapping, gear hobbing, and broaching operations
- Deep drawing and stamping lubricants for automotive sheet metal forming
- Gear cutting and threading fluids for high-alloy steel machining
- Cold forming and wire drawing lubricants requiring maximum EP performance
- Industrial metalworking greases for severe service applications
Key Features
- Excellent extreme pressure performance for heavy-duty cutting, forming, and stamping operations
- High chlorine content grades deliver unmatched EP film formation under ultra-high contact pressures
- Long chain grades (C18-30) offer improved environmental profile versus short-chain variants
- Synergistic with sulfurized and phosphorus EP additives for balanced heavy-duty cutting fluid formulations
