Description

(Hepta(Methacryloxyethoxy))(2,4,6-Tribromophenoxy)Cyclotetraphosphazene is a highly functionalized, halogenated cyclotetraphosphazene derivative designed as a reactive flame retardant and cross-linking agent. This compound matters because it combines the high thermal stability and char-forming properties of phosphazenes with the radical-polymerizable methacrylate groups and flame-retardant efficacy of bromine, offering a multifunctional solution for enhancing material properties. It is primarily needed by formulators and polymer scientists in the plastics, coatings, and advanced composites industries seeking to develop inherently flame-retardant, high-performance polymers without compromising processability.

Application

• Reactive Flame Retardant for Acrylic Resins & Polymers: Incorporated into methacrylate-based systems (e.g., PMMA, UV-curable coatings, adhesives) to provide durable, non-blooming flame retardancy.
• Cross-linking Monomer for High-Temperature Thermosets: Used to create densely cross-linked polymer networks with enhanced thermal stability, mechanical strength, and flame resistance for advanced composites.
• Additive for Epoxy Resin Systems: Imparts flame retardant properties to epoxy formulations used in electronics encapsulation, laminates, and structural adhesives.
• Component in Intumescent Coatings: Acts as a carbonific and blowing agent catalyst in coatings designed to swell and form an insulating char layer under heat.
• Modifier for Polyolefins and Engineering Plastics: Can be grafted or copolymerized to improve the fire performance of materials like polyethylene, polypropylene, and polyamides.
• Synthesis of Specialty Dendrimers and Star Polymers: Serves as a multifunctional core molecule for constructing complex polymeric architectures with tailored properties.
