Description

Amines, Polyethylenepoly-, Reaction Products With Succinic Anhydride Polybutenyl Derivs. is a high-performance polyisobutylene succinimide (PIBSI) derivative, widely recognized as a critical ashless dispersant additive. This compound is engineered to effectively control sludge, varnish, and deposit formation in lubricating oils and fuels. It is essential for formulators in the lubricants and fuel additives industries seeking to enhance engine cleanliness, extend equipment life, and meet stringent performance specifications.

Application

• Primary dispersant in engine oil formulations (passenger car motor oils, heavy-duty diesel oils).
• Key component in marine and industrial lubricants to prevent deposit buildup.
• Additive for gasoline and diesel fuel to improve injector/combustion chamber cleanliness.
• Dispersant in automatic transmission fluids (ATF) and other functional fluids.
• Intermediate for the synthesis of other specialty lubricant additives (e.g., post-treated dispersants).
• Used in grease formulations to enhance stability and performance.

Quality Control

Our production of this ashless dispersant adheres to rigorous quality control protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as nitrogen content, total base number (TBN), viscosity, and chlorine content are strictly monitored. A Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at ambient temperatures (15-25°C/59-77°F). Keep away from strong oxidizing agents. For long-term storage, blanket with dry nitrogen to minimize moisture absorption and oxidation.
