Polyisobutylene Polysuccinimide Dispersion Additive
Advanced Soot Management for Ultra-Long Drain & Biofuel Applications
Premium Dispersion Additive for Engine Protection
This product prepared from high-active polyisobutylene (Molecular weight 1300) by thermal adduction process has excellent thermal stability, good detergency and sludge dispersancy at low temperature. This advanced dispersion additive can inhibit the formation of carbon and paint film at engine piston. It is mainly used for middle and high-grade internal combustion engine oil and serves as an essential dispersion additive for producing petrochemical aid, fuel detergent, and emulsifier of civil explosive.
