Quality Control

Our production of Hexanedioic Acid, Polymer With 1,3-Butanediol adheres to stringent quality management protocols. Each batch is characterized for critical parameters including molecular weight distribution, acid value, hydroxyl value, and thermal properties to ensure consistent performance. Certificates of Analysis (COA) documenting these specifications are available upon request, supporting 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); containers must be kept tightly sealed to prevent moisture absorption, which can affect polymer properties.
