Quality Control

Our production of 1,12-Dodecanedioic Acid, Polymer With 1,6-Hexanediol adheres to stringent quality management protocols. Each batch is characterized for critical parameters including hydroxyl value, acid value, molecular weight distribution, and viscosity to ensure consistency and performance. Certificates of Analysis (COA) documenting these 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 (typically 15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product properties.
