Quality Control

Our 2-Propenoic Acid, 2-Methyl-, Polymer With Diethenylbenzene And Ethenylbenzene is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance characteristics such as ion-exchange capacity, particle size distribution, moisture content, and chemical stability. Certificates of Analysis (COA) documenting these parameters are available upon request. We can supply grades suitable for industrial, laboratory, and specialized applications.

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 strong oxidizing agents and strong bases. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture uptake, which can affect performance.
