Quality Control

Our production of this advanced polymer adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance. Key parameters such as molecular weight distribution, isocyanate content, and thermal properties are monitored. Certificates of Analysis (COA) detailing specific lot specifications are available upon request. Manufacturing follows ISO 9001 quality management principles, and the product can be tailored to meet relevant industry standards.

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). Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed to prevent absorption of atmospheric moisture. Separate from strong oxidizers, acids, and bases.
