High Molecular Weight Polyisobutylene Succinimide - Premium Dispersants in Engine Oil
Ultra-Performance Dispersants in Engine Oil for Severe Conditions
It is made of highly active polyisobutylene and is produced by thermal addition process. It has high temperature mud dispersibility and can inhibit the formation of carbon deposits and paint films on piston oil pistons. Its high temperature dispersibility is comparable to traditional T154 and T155 products.
Product Introduction
This high molecular weight (Mn >2300) polyisobutylene succinimide represents advanced dispersants in engine oil technology. Engineered to combat sludge, varnish, and carbon deposits in extreme-temperature engines, it delivers superior soot handling and deposit control for extended drain intervals.
Advantages of Our Dispersants in Engine Oil
- Molecular Weight Advantage
PIB backbone (Mn 2300-2500) provides 40% higher soot dispersion vs. standard succinimides – essential for effective dispersants in engine oil.
- Thermal Endurance
Maintains dispersancy integrity at 280°C+ (reduces turbo varnish by 60% in Mack T-11 tests).
- Boron Synergy
Boron content (≥0.4% wt.) enhances anti-wear performance and oxidation stability (ASTM D2893).
- Low-SAPS Compliance
Zero phosphorus, sulfur <0.2%, sulfated ash <0.5% for Euro VII/China VI compatibility.
- Biofuel Resistance
Prevents sludge formation in B100 biodiesel and E85 ethanol blends (ASTM D7548 validated).
Key Applications for Dispersants in Engine Oil
- Heavy-duty diesel oils (API CK-4/FA-4)
- Hybrid drivetrain fluids (100,000+ km drain capability)
- Marine engines (MAN ES 40-60BN cylinder oils)
- Gas engine lubricants (CNG/LNG formulations)
- 100% bio-lubricants (ISO 15380 HEES hydraulic fluids)
These advanced dispersants in engine oil provide comprehensive protection across diverse engine types.
Reference Dosage
Recommended Dosage: 1–10% (adjust based on base oil and performance targets).
