Quality Control

Our production of Polyamide Ester Of Pyromellitic Dianhydride With 4,4-Oxydianiline Polymer adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including inherent viscosity, solid content, and residual solvent levels to meet precise application requirements. Certificates of Analysis (COA) documenting full specifications are available upon request, supporting compliance in regulated supply chains.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept sealed to prevent moisture absorption, which can affect product stability and performance. Keep away from heat sources and incompatible materials.
