Quality Control

Our 1,3-Benzenedicarboxylic acid polymer is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color. Certificates of Analysis (COA) documenting these specifications are available upon request. Our quality protocols are designed to meet the rigorous demands of industrial and specialty chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids, bases, and sources of ignition. Under these conditions, the product is stable for extended periods. The original container is designed to maintain product integrity.
