Quality Control

Our production of this specialty copolyester adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including intrinsic viscosity, acid value, glass transition temperature (Tg), and color. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment 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). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect processing and final product properties.
