Quality Control

Our production of this copolyester adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 heat sources and open flame. Under these conditions, the product is stable for extended periods. The container must be kept tightly sealed when not in use to prevent moisture absorption and contamination.
