Quality Control

Our Polyoxypropylenated Pentaerythritol,Polymethylenepolyphenyleneisocyanate Polymer is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as isocyanate content, viscosity, and functionality. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under a dry atmosphere (e.g., under dry nitrogen) to prevent reaction with atmospheric moisture. Recommended storage temperature is 15-25°C. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and water.
