Boron-Phosphated PIB Bis-succinimide
Boron-phosphated PIB bis-succinimide — a dual-modified dispersant adding both boron and phosphorus for enhanced anti-wear, oxidative stability and seal compatibility alongside strong dispersancy.
The dual-modified dispersant for enhanced protection
Adding both boron and phosphorus to a bis-succinimide dispersant enhances anti-wear and oxidative stability while retaining strong dispersancy and seal compatibility.
Boron-phosphated PIB bis-succinimide is a dual-modified dispersant, carrying both boron and phosphorus on the bis-succinimide structure. The combination enhances anti-wear performance and oxidative stability beyond boration alone, while retaining the strong dispersancy and improved seal compatibility of a modified bis-succinimide. This makes it a sophisticated multifunctional dispersant for high-performance modern engine oils that want to combine several functions efficiently. It is part of the ashless dispersant family.
Boron-Phosphated PIB Bis-succinimide — typical properties
Representative typical values for boron-phosphated PIB bis-succinimide. Indicative only — exact values vary by grade and are confirmed on the TDS and batch COA.
| Property | Typical Value | Method / Note |
|---|---|---|
| Appearance | Amber to brown viscous liquid | Visual |
| Total Base Number (TBN) | ~15–45 mg KOH/g | ASTM D2896 · grade-dependent |
| Nitrogen content | ~1–2.2 wt% | Polyamine head |
| Boron content | Present | Borated modification |
| Phosphorus content | Present | Phosphated modification |
| Kinematic viscosity (100°C) | ~150–600 mm²/s | ASTM D445 |
| Density (15°C) | ~0.9–0.95 g/cm³ | Typical |
