Product Technical Details

Product Overview

Cresyl Diphenyl Phosphate (CDP) represents a premier class of organophosphate compounds designed for advanced industrial applications. As a multifunctional additive, it serves primarily as a flame retardant plasticizer, delivering exceptional performance in polymer matrices where safety and durability are paramount. Our manufacturing process ensures high purity levels, making this chemical an ideal choice for demanding engineering plastics and rubber compounds.

This specialized phosphate ester combines effective flame retardancy with superior plasticizing efficiency. Unlike conventional additives, CDP maintains structural integrity under thermal stress while providing low volatility characteristics. This balance makes it indispensable for industries requiring compliance with strict fire safety regulations without compromising mechanical properties.

Key Performance Advantages

  • Exceptional hydrolysis stability ensures long-term performance in humid environments.
  • Low volatility reduces emissions during processing and product lifecycle.
  • Superior electrical insulation properties suitable for cable and wire applications.
  • Excellent compatibility with PVC, rubber, and various synthetic resins.
  • Enhanced wear resistance contributes to the longevity of final products.
  • Low temperature flexibility prevents brittleness in cold conditions.

Industrial Applications

The versatility of Cresyl Diphenyl Phosphate allows for widespread usage across multiple sectors. It is predominantly utilized in the formulation of polyvinyl chloride (PVC) and vinyl copolymers, where it imparts critical flame retardant properties. Additionally, it serves as a functional additive in polyvinyl acetal and cellulose derivatives, including cellulose acetate and butylated cellulose acetate.

In the rubber industry, CDP enhances both natural and synthetic rubber compounds, improving fire resistance and mechanical strength. Beyond polymers, it functions effectively as an additive in gasoline and lubricant formulations, contributing to overall system stability and safety. Its role as a plasticizer ensures optimal processing characteristics during manufacturing.

Packaging and Storage

To maintain product integrity, we package Cresyl Diphenyl Phosphate in 200kg galvanized iron drums. This packaging solution protects the chemical from contamination and physical damage during transit. Proper storage is essential for preserving quality. The product should be kept in a dry, ventilated warehouse away from direct sunlight and moisture.

Safety protocols dictate keeping containers sealed when not in use. As a Hazard Class 9 material, it requires standard chemical handling procedures. Avoid exposure to open flames or high heat sources. Our logistics team ensures compliant shipping documentation is provided with every order to facilitate smooth global delivery.
