Pour Point Depressant
Advanced Pour Point Depressant Solutions
Optimize Low-Temperature Fluidity & Performance for Industrial Lubricants
Pour Point Depressant (PPD) is a critical additive that improves low-temperature fluidity by modifying wax crystal structures. These advanced pour point depressant additives are essential for maintaining lubricant performance in extreme cold environments. Our innovative PPD technology ensures your fluids maintain optimal flow characteristics even in the most challenging conditions.
- Significant Pour Point Reduction: Lowers the pour point of 0# diesel to -35°C (ASTM D97).
- Optimized Low-Temperature Pumpability: Ensures -40°C MRV viscosity ≤20,000 cP (ASTM D4684).
- Wax Crystal Inhibition: Restricts wax crystal size to ≤5 μm (observed via polarized light microscopy).
- Synergistic Effects: Collaborates with viscosity modifiers to maintain viscosity-temperature characteristics.

- Scientific Formulation
This advanced pour point depressant technology ensures optimal performance across temperature extremes while maintaining lubricant integrity.
Golden Ratio Formula for PPD Dosage:
PPD dosage (%) = (Base oil wax content % × 0.2) + (Target pour point difference °C × 0.05)
Operational Guidelines:
Addition Temperature: Must exceed base oil cloud point +10°C.
Timing: Add at least 15 minutes after detergent addition.
Mixing Prohibition: Avoid direct mixing with high-alkaline additives.
Storage: Protect from light and moisture (humidity <40% RH).
