PIBSI – Polyisobutylene Succinimides

PIBSI-polyisobutylene-Succinimides

 PIBSI is a dispersant/detergent additive is used in multifunctional packages for middle distillates, especially for use in premium diesel fuel or heating oil. It considerably reduces soot formation and improves the fuel efficiency/economy . It provides excellent low temperature sludge and varnish control in gasoline engines and effective dispersancy for deposit control in both medium-speed and high temperature super-charged diesel engines. PIBSI also helps to reduce maintenance costs by providing corrosion inhibition. We manufacture PIBSI by the amination of the anhydride group of the PIBSA molecule with long chain polyamines such as DETA, TETA and TEPA.
