Boronated polyisobutenyl succinimide (Boronated PISA) is a type of polymer additive that is used as a friction modifier in lubricants, such as motor oils and gear oils, to reduce wear and tear on metal components by reducing the friction between them.
It is a polyisobutene-based polymer backbone that is modified with succinic and boronic acid groups.
The boronic acid groups are more polar than the succinic acid groups and provide greater lubricity while also allowing the additive to disperse more easily.
The succinic acid groups provide a higher degree of thermal stability than the boronic acid groups.
This combination of polar and non-polar groups is what allows the Boronated PISA to function as an effective friction reducer while also being thermally stable.
Boronated PISA can be found in many automotive products, such as motor oils and gear oils.
It is used to reduce wear and tear on metal components, including bearings and valves, by reducing friction between them. Additionally, it improves the performance of fluids by increasing lubricity and thermal stability.
In addition to automotive applications, it can also be found in industrial products, such as metalworking fluids, way oil, and transmission fluid.

Boronated polyisobutenyl succinimide is generally used with oxidation inhibitors and acid neutralizing additives in gasoline and diesel engine oils. It provides excellent low temperature sludge and varnish control in gasoline engines, and effective dispersancy in diesel engine, natural gas and marine cylinder lubricants.
Boronated polyisobutenyl succinimide has the good compatibility with metal detergents, ZDDP and other series of additives ,and has the good synergistic effect with additives. It is mainly used for blending high-quality gasoline engine oils and diesel engine oils.
