Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, hydroxyl value, isocyanate content, and residual monomers are monitored using advanced analytical techniques including GPC, FT-IR, and titration methods. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance protocols.

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 / 59-77°F). Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed to prevent absorption of atmospheric moisture which can affect product performance.
