Quality Control

Our production of 1,4-Benzenedicarboxylic Acid, Polymer With 2,2'-Oxybis[Ethanol] adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance. Each lot is characterized for critical parameters including hydroxyl value, acid value, viscosity, and molecular weight distribution. Certificates of Analysis (COA) documenting these specifications are provided with every shipment 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). This material is hygroscopic (moisture-sensitive); keep containers tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
