Quality Control

Our Poly(4-Hydroxy Benzoic Acid-Co-Ethylene Terephthalate) is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance characteristics such as melt viscosity, thermal transition temperatures, and mechanical properties. Certificates of Analysis (COA) documenting key specifications are available upon request 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 strong heat sources and open flames. The material is hygroscopic (moisture-sensitive); ensure the original packaging is sealed after use to prevent moisture absorption which can affect processing characteristics.
