Quality Control

Our production of this brominated epoxy polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including bromine content, epoxy equivalent weight (EEW), viscosity, and thermal stability to ensure consistent performance as a flame retardant. Certificates of Analysis (COA) detailing batch-specific results are provided with every shipment.

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 heat, sparks, and open flame. This product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption which may affect reactivity.
