Quality Control

Our Terephthalic Acid, Polymer With Benzene-1,2,4-Tricarboxylic Anhydride, Ethane-1,2-Diol,4,4'-Methylenedianiline And Glycerol is manufactured under a strict quality management system. Every batch undergoes rigorous testing for key parameters including viscosity, gel time, acid value, and thermal properties to ensure consistent performance and batch-to-batch reliability. Certificates of Analysis (COA) documenting full specifications are available upon request, and production can be aligned with relevant industry standards such as ISO 9001.

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, open flames, and incompatible materials such as strong oxidizing agents. The container must be kept tightly sealed when not in use to prevent moisture absorption and contamination.
