Phenoxycyclophosphazene

Product Overview

Phenoxycyclophosphazene, chemically known as Hexaphenoxycyclotriphosphazene (HPCTP), represents a advanced class of organic phosphorus-nitrogen hybrid compounds. Designed specifically for high-performance polymer modification, this substance serves as a highly efficient additive halogen-free flame retardant. Its unique molecular architecture combines phosphorus and nitrogen elements within a stable cyclotriphosphazene ring structure, delivering exceptional thermal resistance and fire suppression capabilities without the environmental drawbacks associated with traditional halogenated systems.

As a leading manufacturer, we supply this material with stringent quality controls to ensure consistency across global supply chains. The product is characterized by its white crystalline appearance and high purity levels, making it an ideal choice for demanding applications in electronics, automotive components, and advanced composite materials.

Technical Specifications

Industrial Applications

This versatile flame retardant is extensively utilized across a broad spectrum of polymer matrices. It is particularly effective in Polycarbonate (PC) and PC/ABS blends, where an addition level of merely 8-10% achieves the UL-94 V-0 flame retardancy rating. Beyond engineering plastics, it demonstrates superior performance in epoxy resin systems, facilitating the production of large-scale integrated circuit packaging materials (EMC) with enhanced safety profiles.

Further applications include benzoxazine resin glass cloth laminates, polyethylene modifications achieving Limiting Oxygen Index (LOI) values between 30 and 33, and viscose fiber spinning solutions. The chemical is also compatible with LED encapsulation materials, powder coatings, and various potting compounds, providing reliable fire safety in electronic and electrical assemblies.

Performance Advantages

• Ecological Safety: The P-N hybrid skeleton ensures halogen-free composition, eliminating toxic gas emissions and secondary pollution during combustion.
• Thermal Stability: Capable of withstanding continuous exposure to temperatures exceeding 250°C while maintaining integrity under ultra-low temperature conditions.
• High Efficiency: Requires significantly lower loading rates compared to conventional retardants like BDP or RDP to achieve equivalent fire ratings.
• Material Compatibility: The stable structure ensures minimal impact on the mechanical and physical properties of the host polymer matrix.
• Handling Convenience: Available as a free-flowing white crystal that requires no pre-heating and utilizes standard packaging for safe transportation.

Storage and Handling

To maintain optimal quality, store this product in a dry, well-ventilated warehouse away from direct sunlight and moisture sources. Ensure containers remain sealed when not in use to prevent contamination. The material should be kept away from open flames and incompatible substances. Standard industrial safety protocols apply during handling and processing.
