Polyisobutylene Succinic Anhydride PIBSA1300

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.

Mn=1300 PIB backbone enables higher viscosity dispersants with superior soot suspension (40% improvement vs. Mn=1000 PIBSA per ASTM D7218).

≤0.8% free MA content minimizes gelation risk during dispersant synthesis.

Stable processing up to 80°C without decomposition (TGA-verified).

Zero chlorine, REACH/ECHA Annex XVII compliant.

Core material for:
✓ Boronated succinimide dispersants
✓ Metalworking fluid emulsifiers
✓ Fuel detergent additives
