Quality Control

Our production of this advanced polymer adheres to rigorous quality management systems to ensure batch-to-batch consistency and performance reliability. While specific grades can be tailored, standard quality parameters include monomer conversion rate, residual isocyanate content, solution viscosity, and functional group analysis. A comprehensive Certificate of Analysis (COA) detailing relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and potential quality degradation.
