Quality Control

Our production of Butanedioic Acid, Polyisobutenyl Derivs., Esters With Pentaerythritol adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including saponification number, total base number (TBN), viscosity, and nitrogen content (if applicable). A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive and should be stored away from direct light. As it is easily oxidized, prolonged storage is recommended under an inert atmosphere (e.g., nitrogen blanket) for optimal long-term stability. Keep away from strong oxidizing agents.
