Quality Control

Our Polyacrolein is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets defined specifications for parameters such as aldehyde content, molecular weight distribution, and purity. Certificates of Analysis (COA) documenting these results are provided to guarantee traceability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider keeping under an inert atmosphere such as nitrogen. Keep away from strong oxidizing agents, strong bases, and sources of heat.
