Quality Control

Our Dimethyl Terephthalate, Polymer With 1,4-Cyclohexanedimethanol is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance in key parameters such as intrinsic viscosity, color, thermal properties, and mechanical strength. Certificates of Analysis (COA) documenting full specifications are available upon request, supporting compliance with relevant industry and regulatory requirements.

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 excessive heat to maintain polymer integrity. Ensure original packaging remains sealed until use to prevent moisture absorption.
