Product Technical Details

Product Overview

Resorcinol Tetraphenyl Diphosphate represents a class of advanced organophosphate compounds engineered specifically for high-performance polymer applications. As a non-halogenated flame retardant, this chemical solution addresses the growing industrial demand for environmentally compliant materials without sacrificing mechanical integrity. Our manufacturing process ensures consistent molecular structure, delivering reliable fire resistance across various thermoplastic matrices.

This product is characterized by its low volatility and exceptional thermal stability, making it an ideal choice for high-temperature processing environments. Unlike traditional halogenated additives, this phosphate ester minimizes the release of corrosive gases during combustion, aligning with modern safety regulations and green chemistry initiatives. The viscous liquid form facilitates easy incorporation into polymer melts, ensuring uniform dispersion throughout the final composite material.

Industrial Applications

The primary utility of Resorcinol Tetraphenyl Diphosphate lies in the modification of engineering plastics. It is extensively used in blends such as Polycarbonate and Acrylonitrile Butadiene Styrene (PC/ABS), as well as Polyphenylene Oxide and High Impact Polystyrene (PPO/HIPS). These materials are critical in automotive components, electronic housings, and electrical connectors where fire safety standards are stringent.

By integrating this flame retardant, manufacturers can achieve UL94 V-0 ratings while maintaining the impact strength and flow properties required for complex injection molding processes. The compatibility with various polymer systems allows formulators to optimize recipes without significant reformulation efforts, serving as a reliable drop-in replacement for legacy additives.

Advantages and Performance

  • Superior thermal stability prevents degradation during high-temperature extrusion.
  • Low volatility reduces fogging issues in automotive interior applications.
  • Halogen-free composition supports eco-friendly product certification.
  • Excellent hydrolytic stability ensures long-term performance in humid conditions.
  • Enhances char formation during combustion to inhibit flame spread.

Storage and Handling

To maintain product integrity, store this chemical in a dry and ventilated warehouse away from direct sunlight. Keep containers sealed to prevent moisture absorption, which could affect hydrolytic stability. Avoid proximity to open flames or ignition sources despite its classification as non-dangerous goods. Standard industrial safety protocols should be followed during handling and transfer operations. Packaging is typically provided in 250kg iron drums to facilitate bulk logistics and safe transportation globally.
