Quality Control

Our Biopol CAS NO 29435-48-1 is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as degree of hydrolysis, viscosity, and residual solvent content are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture.
