Description

Nonylphenyldiphenylphosphate is a high-performance organophosphate compound widely utilized as a flame retardant and plasticizer. Its chemical structure provides excellent thermal stability and compatibility with various polymer matrices, making it a critical additive for enhancing material safety and performance. This product is essential for manufacturers in the plastics, rubber, and coatings industries seeking to meet stringent fire safety regulations without compromising on material properties.

Application

• Primary flame retardant and plasticizer for flexible polyvinyl chloride (PVC) in wire and cable insulation.
• Flame retardant additive in engineering plastics such as polycarbonate (PC), polyurethane (PU), and acrylonitrile butadiene styrene (ABS).
• Functional additive in synthetic rubber formulations to improve flame resistance and processability.
• Plasticizer component for specialty adhesives, sealants, and industrial coatings requiring fire retardancy.
• Additive in textile back-coatings and other fabric treatments to impart flame-retardant properties.
• Used in the formulation of certain hydraulic fluids and lubricants requiring fire-resistant characteristics.

Quality Control

Our Nonylphenyldiphenylphosphate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. The product is tested against rigorous internal specifications, which typically include assay, color, acidity, and moisture content. A Certificate of Analysis (COA) detailing the results for each production lot is available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids, organic solvents, and incompatible materials. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption.
