Quality Control

Our Polyvar is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Quality is verified through a series of analytical tests including identification, assay, and impurity profiling. A Certificate of Analysis (COA) documenting key parameters such as purity, viscosity, and acid value is provided with each shipment to guarantee compliance with your specifications.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
