Quality Control

Our production of Hexanedioic Acid Polymer adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous analytical testing, including determination of NCO/amine content, viscosity, and color index, to meet precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided and can be tailored to support compliance with ISO, REACH, and other relevant global regulatory frameworks.

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 moisture-sensitive (hygroscopic); containers must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong acids, bases, and oxidizing agents.
