Quality Control

Our production of 1,3-Benzenedicarboxylic Acid, Polymer With Hexanedioic Acid And 1,6-Hexanediol adheres to stringent quality management systems. Each batch undergoes rigorous testing for key parameters including intrinsic viscosity, melting point, acid value, and color index to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications 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). Keep away from strong oxidizing agents, strong acids, and strong bases. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption which may affect processing properties.
