Quality Control

Our production of this block copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as molecular weight distribution, hydroxyl value, isocyanate content, and thermal properties are rigorously monitored. Certificates of Analysis (COA) detailing specific lot specifications are available upon request to support your quality assurance and regulatory compliance needs.

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. Separate from strong oxidizing agents.
