Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Quality is assured through batch-specific analysis of key parameters such as molecular weight distribution, thermal properties, and purity. Certificates of Analysis (COA) documenting these specifications are available upon request. Our commitment to consistent quality and supply reliability supports your manufacturing process and final product performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong bases, strong oxidizing agents, and moisture. For long-term storage, consider an inert atmosphere to prevent hydrolysis of reactive chloride groups.
