HPCTP, chemical name hexaphenoxycyclotriphosphazene, CAS 1184-10-7, is high purity halogen-free cyclic phosphazene flame retardant powder. Based on phosphorus-nitrogen synergistic flame retardant principle, it possesses outstanding thermal stability and low volatility. The high purity grade reduces impurities, minimizing adverse impacts on mechanical, optical and dielectric properties of substrates. It has good compatibility with polycarbonate, nylon and epoxy resin, widely used for halogen-free
Product DetailsChemical IdentityProduct Name: Hexaphenoxycyclotriphosphazene, HPCTP CAS No.: 1184-10-7 Chemical Type: Halogen-free cyclic phosphazene additive flame retardant Physical Form: White fine powder Core Feature: High purity halogen-free phosphazene powder for PC, Nylon and Epoxy
Key Performance & TDSHigh purity HPCTP contains low impurity content, lowering risks of discoloration and performance degradation in final products. Its phosphorus-nitrogen synergistic system forms dense protective char layer under flame, blocking heat and oxygen diffusion. It has high decomposition temperature, keeping stable during high-temperature extrusion, injection molding and epoxy curing without foaming or decomposition. Halogen-free formula releases low smoke and no corrosive halogen gas during combustion. Fine powder achieves homogeneous dispersion inside PC, nylon and epoxy matrix. No blooming or precipitation occurs at recommended dosage. It can help finished materials reach UL94 V-0 flame retardant rating.
