Quality Control

Our production of Acetic Acid Ethenyl Ester, Polymer With Ethenol, Cyclic Acetal With Butanal adheres to stringent quality management protocols. Each batch is characterized for critical parameters including molecular weight distribution, degree of acetalization, and residual monomer content to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) detailing these specifications are provided with every shipment.

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). Keep away from heat sources and open flames. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption which may affect properties.
