Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including hydroxyl value, acid value, viscosity, and molecular weight distribution. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant industry frameworks, and our quality systems are designed to meet the demands of ISO-certified manufacturing environments.

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); ensure containers are sealed after use to prevent absorption of atmospheric moisture. Keep away from strong oxidizing agents, strong acids, and strong bases.
