Description

1,4-Benzenedicarboxylic Acid, Compds. With Polyisobutenyl Succinic Anhydride-Tetraethylenepentamine Reaction Products is a high-performance chemical additive derived from the reaction of polyisobutenyl succinic anhydride (PIBSA) with tetraethylenepentamine, subsequently compounded with terephthalic acid. This specialized compound is engineered to deliver superior performance as a dispersant and detergent in demanding industrial formulations. It is primarily utilized in the lubricant and fuel additive industries, where it effectively controls deposits, stabilizes viscosity, and enhances the cleanliness of engines and machinery.

Application

• Lubricant Additive: Acts as a multifunctional dispersant and detergent in engine oils, hydraulic fluids, and industrial lubricants to prevent sludge and varnish formation.
• Fuel Additive: Used in gasoline and diesel formulations to keep fuel injectors and intake systems clean, improving combustion efficiency.
• Industrial Cleaners & Degreasers: A key component in heavy-duty cleaning formulations for industrial equipment and parts.
• Metalworking Fluids: Incorporated as a stabilizer and anti-deposit agent in coolants and cutting fluids.
• Corrosion Inhibitor Packages: Functions as a component in additive packages designed to protect metal surfaces in closed-loop systems.
• Asphalt Modifier: Can be used to improve the rheological properties and aging resistance of asphalt binders.
