T154B Boronized Polyisobutylene Bis-Succinimide
Boronized Polyisobutylene Succinimide Dispersing Agents
Advanced Ashless Dispersant for Modern Engine Protection
T154B is made of polyisobutylene and is a boronized ashless dispersant produced by a thermal addition process. It has good sludge dispersibility, can inhibit the formation of carbon deposits on pistons, and has excellent heat resistance, oxidation resistance and wear resistance.
Product Introduction
T154B is a boron-modified polyisobutylene bis-succinimide ashless dispersant engineered to prevent low-temperature sludge, control high-temperature deposits, and enhance lubricant stability in demanding engines. By integrating boron chemistry into PIB succinimide technology, it delivers superior dispersancy with added anti-wear and antioxidant benefits. Key applications include premium gasoline/diesel engine oils, marine lubricants, and biofuel-compatible formulations.
- Dual-Temperature Deposit Control
Eliminates low-temperature sludge and reduces carbon/varnish on piston rings and turbochargers at ≤250°C.
- Boron-Enhanced Performance
Boron content (≥0.35% wt.) provides anti-wear properties and boosts oxidation resistance.
- Ashless & Eco-Compliant
Chlorine-free (<0.5%), REACH/EPA compliant, and compatible with low-SAPS formulations.
- Synergistic Compatibility
Optimizes performance with metal detergents (e.g., sulfonates) and ZDDP antiwear agents.
- Biofuel Resilience
Maintains stability in biodiesel (B20/B30) and ethanol-blended (E10-E85) lubricants.
Application
