Quality Control

Our Poly(Ethylene-Co-Acrylic Acid, Sodium Salt) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of acid number, viscosity, solids content, and ionic character. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance protocols.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
