Quality Control

Our production of this flame retardant polymer adheres to strict quality control protocols to ensure batch-to-batch consistency and performance reliability. Quality is verified through analytical methods including FTIR, GPC, and halogen content analysis. A comprehensive Certificate of Analysis (COA) detailing key parameters such as phosphorus content, bromine content, viscosity, and thermal stability is provided with every shipment.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent moisture absorption, which can affect product performance.
