High Molecular Weight Polyisobutylene Succinimide

Description

Product Introduction

High Molecular Weight Polyisobutylene Succinimide is a high molecular weight ashless dispersant prepared from highly reactive isobutylene(Mn=2300) by thermal adduction process. It has excellent dispersancy & solubilization effect on oil sludge and soot; and can effectively control the increase of the engine oil viscosity . It doesn’t contain chlorine.

High Molecular Weight Polyisobutylene Succinimide is a specific type of additive used in lubricants and industrial oils. It is made by reacting high molecular weight polyisobutylene with maleic anhydride, followed by a reaction with an alkylene polyamine.

This additive is commonly used in engine oils, hydraulic fluids, and gear oils to improve their dispersant and detergency properties. It helps to keep the engine or machinery clean by effectively dispersing and suspending harmful deposits, sludge, and varnish. It also helps to prevent the formation of harmful acids and reduces the risk of corrosion.

High Molecular Weight Polyisobutylene Succinimide contains high molecular weight polyisobutylene, which contributes to its exceptional dispersant and detergency properties. This allows it to effectively clean and remove deposits, ensuring better lubricant flow and reducing the risk of equipment failure.

Additionally, this additive offers excellent thermal stability and oxidative resistance, helping to maintain the lubricant’s performance even under high operating temperatures. It also helps to resist the formation of oxidation by-products, ultimately prolonging the life and reliability of the lubricated components.

Furthermore,  High Molecular Weight Polyisobutylene Succinimide can improve the viscosity index and shear stability of the lubricant. This ensures that the lubricant maintains its viscosity and lubricating properties even under high temperature and shear conditions.

In summary,  High Molecular Weight Polyisobutylene Succinimide is a valuable additive that provides enhanced dispersant, detergency, thermal stability, and oxidative resistance properties to lubricants and industrial oils. It helps to maintain cleanliness, reduce wear, prevent corrosion, and ensure optimal performance, making it an important component in high-performance formulations.
