Quality Control

Our production of this advanced copolyester follows a strict quality management system aligned with ISO 9001 standards. Each batch undergoes comprehensive analysis to ensure consistency in key parameters such as acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee traceability and performance reliability for your formulation 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 flames. This material is hygroscopic (moisture-sensitive); ensure containers are sealed when not in use to prevent moisture absorption, which can affect processing properties.
