Description

Alkyl Diphenyl Phosphate is a versatile organophosphate compound widely used as a flame retardant and plasticizer. Its primary value lies in its ability to impart fire resistance while maintaining the flexibility and processability of polymer materials. This product is essential for manufacturers in the plastics, rubber, and coatings industries seeking to enhance the safety and performance of their products. It is particularly valued for its compatibility with various polymer systems and its effectiveness in reducing flammability.

Application

• Primary flame retardant and plasticizer for flexible polyurethane (PU) foams.
• Flame retardant additive for engineering plastics such as polycarbonate (PC) and PC/ABS blends.
• Functional additive in PVC and other vinyl polymers to improve flame resistance.
• Plasticizer for synthetic rubbers and elastomers requiring fire safety properties.
• Component in fire-resistant hydraulic fluids and lubricants.
• Additive in adhesives, sealants, and coatings to meet fire safety regulations.
• Used in the formulation of wire and cable insulation compounds.
• Potential component in specialty polymer applications requiring combined plasticization and flame retardancy.

Quality Control

Our Alkyl Diphenyl Phosphate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency and performance, including assay, color, acidity, and specific gravity. Certificates of Analysis (COA) are provided with every shipment, detailing the product's compliance with agreed specifications. We support our global clients with documentation relevant to REACH and other regional regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong bases and incompatible materials such as strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to prevent moisture absorption.
