Polyisobutylene Succinic Anhydride Thermal Adduction PIBSA Emulsifiers For Explosives
High-Viscosity Intermediate for Premium Ashless Dispersants
PIBSA1300
Product Introduction
PIBSA1300 is a polyisobutylene succinic anhydride intermediate synthesized from high molecular weight PIB (Mn=1300) and maleic anhydride. Designed for advanced ashless dispersant manufacturing, it delivers superior thermal stability and enhanced deposit control capabilities. This high-viscosity intermediate is essential for formulating heavy-duty engine oils, marine lubricants, and industrial additives requiring extended soot-handling performance.
- Optimized Molecular Weight
Mn=1300 PIB backbone enables higher viscosity dispersants with superior soot suspension (40% improvement vs. Mn=1000 PIBSA per ASTM D7218).
- Low Free Anhydride
≤0.8% free MA content minimizes gelation risk during dispersant synthesis.
- Thermal Resilience
Stable processing up to 80°C without decomposition (TGA-verified).
- Eco-Compliance
Zero chlorine, REACH/ECHA Annex XVII compliant.
- Multi-Functional Utility
Core material for:
✓ Boronated succinimide dispersants
✓ Metalworking fluid emulsifiers
✓ Fuel detergent additives
