Highly reactive polyisobutylene succinimide is a premium polymer additive renowned for its enhanced reactivity, derived from the reaction of high-activity polyisobutylene with maleic anhydride followed by amination. This advanced formulation delivers superior performance compared to conventional grades, making it a preferred choice in high-demand industrial applications.

Its primary function is as a high-efficiency dispersant and detergent in lubricating oil formulations. In automotive, marine, and industrial engine oils, it effectively disperses combustion-generated soot, sludge, and oxidation byproducts. By preventing the agglomeration of these contaminants, it inhibits the formation of hard deposits on pistons, valves, and other critical engine components, ensuring optimal engine cleanliness even under extreme operating conditions such as high temperatures and heavy loads.

Additionally, it exhibits excellent viscosity index improvement and pour point depression properties. It helps maintain stable oil viscosity across a wide temperature range, enhancing lubrication reliability in both cold starts and high-temperature operation. This not only extends the service life of the lubricating oil but also reduces friction and wear, contributing to improved fuel efficiency and longer engine lifespan.
