Quality Control

Our production of Dipropylene Glycol, Ethyl Acrylate, Maleic Anhydride, Methyl Methacrylate Polymer adheres to a stringent quality management system. Every batch is tested against critical parameters including monomer content, molecular weight distribution, acid value, and viscosity to ensure it meets precise customer and application requirements. Certificates of Analysis (COA) documenting purity, physical properties, and performance characteristics are provided with each shipment. We support compliance with global regulatory frameworks such as REACH.

Storage

Preserve in a tightly closed container, protected from light. This polymer is hygroscopic (moisture-sensitive). Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Store away from incompatible materials such as strong oxidizing agents, bases, and amines.
