Description

Butanedioic Acid, Polybutenyl Derivs., Esters With Pentaerythritol is a high-performance polymeric ester additive derived from succinic acid, polybutene, and pentaerythritol. This specialized chemical is engineered to provide exceptional dispersancy, detergency, and viscosity-modifying properties in demanding formulations. It is a critical component for manufacturers in the lubricant and fuel additive industries seeking to enhance product stability and performance under extreme conditions.

Application

• Lubricant Additive: Primarily used as a dispersant and detergent in engine oils (both gasoline and diesel) to keep engines clean by preventing sludge and varnish formation.
• Fuel Additive: Acts as a detergent in gasoline and diesel fuels to clean and maintain fuel injectors and intake valves, improving combustion efficiency.
• Industrial Lubricants: Employed in gear oils, hydraulic fluids, and greases to improve thermal stability and control viscosity.
• Metalworking Fluids: Provides dispersancy to keep metal fines and other contaminants suspended, extending fluid life and tool performance.
• Ashless Additive Formulations: Valued for its ashless nature, making it suitable for applications where metallic residue from additives is undesirable.

Quality Control

Our production of Butanedioic Acid, Polybutenyl Derivs., Esters With Pentaerythritol adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as total acid number (TAN), saponification number, nitrogen content, and viscosity are rigorously tested against internal and customer specifications. Certificates of Analysis (COA) documenting these results are provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and oxidation.
