Quality Control

Our production of this polyamide copolymer adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing to ensure consistent purity, molecular weight distribution, and thermal properties. Certificates of Analysis (COA) detailing key parameters such as intrinsic viscosity, melting point, and residual monomer content are provided to guarantee the material meets your specific application requirements.

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 the original container sealed to prevent moisture absorption, which can affect processing and final properties.
