Characteristics and uses of boride high molecular weight polyisobutylene succinimide

Polyisobutenyl succinimide (T154A) is an ashless dispersant prepared from high activity polyisobutylene (=1000) by thermal addition process. It has good cleaning and dispersing properties and can inhibit the formation of carbon deposits and paint films on engine pistons. It has good cleaning and dispersibility, and does not contain chlorine.

Boride High Molecular Weight Polyisobutylene Succinimide

Polyisobutylene succinimide dispersant has excellent solubilizing, peptizing and dispersing effects, and has certain neutralization and adsorption capacity. Since this series of products does not contain metal, almost no ash remains after use, which can avoid the wear of engine parts caused by excessive ash.

At present, most of the polyisobutylene succinimide produced in China adopts the thermal addition process. Different types of polyisobutylene succinimide are prepared by reacting high-activity polyisobutylene with maleic anhydride and polyene polyamine in turn according to a certain proportion. Amines, such as T151 (polyisobutylene bis-succinimide), T154 (polyisobutylene bis-succinimide), T155 (polyisobutylene-polysuccinimide), T161 (high molecular weight polyisobutylene-bis-succinimide) imide)
It is used to prepare medium and high-grade diesel oil, medium and high-grade gasoline engine oil, and low-speed crosshead engine marine cylinder oil, especially suitable for the preparation of environmentally friendly internal combustion engine oil.
