Description

Ammonium Bis(2,3-Dibromopropyl) Phosphate is a halogenated organophosphorus compound primarily valued for its efficacy as a flame retardant. This chemical matters because it provides a synergistic combination of bromine and phosphorus, enhancing fire suppression in various polymer matrices. Industries requiring durable flame-retardant properties for plastics, textiles, and coatings are the primary users of this additive.

Application

• As a reactive or additive flame retardant for polyurethane foams (flexible and rigid).
• Flame-retardant treatment for textiles, including back-coatings for upholstery and drapery fabrics.
• Component in flame-retardant formulations for unsaturated polyester resins and epoxy systems.
• Use in adhesives and sealants requiring enhanced fire safety ratings.
• Potential application in thermoplastic compounds such as polyolefins and engineering plastics.
• Flame-retardant additive for paints, coatings, and related surface treatments.

Quality Control

Our Ammonium Bis(2,3-Dibromopropyl) Phosphate is manufactured under a rigorous quality management system. Each batch is tested to ensure consistent performance as a flame retardant, with key parameters including bromine content, phosphorus content, and thermal stability. A Certificate of Analysis (COA) documenting purity, identity, and relevant specifications is available for every shipment to ensure traceability and compliance.

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, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
