HPCTP, chemical name hexaphenoxycyclotriphosphazene, CAS 1184-10-7, is a halogen-free cyclic phosphazene flame retardant. It is a non-reactive high-efficiency phosphorus-nitrogen synergistic flame retardant powder. It has outstanding thermal stability and low volatility, suitable for high-temperature processing of engineering plastics and epoxy systems. It can endow substrates with excellent flame retardant performance while maintaining good mechanical and dielectric properties. Widely applied i
Product DetailsChemical IdentityProduct Name: Hexaphenoxycyclotriphosphazene, HPCTP CAS No.: 1184-10-7 Chemical Type: Halogen-free cyclic phosphazene flame retardant Physical Form: White fine powder Core Feature: Halogen-free phosphazene for PC, Nylon, PPO, Epoxy and CCL
Key Performance & TDSHPCTP adopts phosphorus-nitrogen synergistic flame retardant mechanism. It promotes dense char layer formation on material surface under fire condition to isolate heat and oxygen. It possesses ultra-high thermal stability, matching high-temperature extrusion, injection molding and epoxy curing processes. Low volatility prevents decomposition and foaming during high-temperature processing. It is halogen-free and releases low smoke without corrosive gas when burning. It retains the original mechanical strength, impact performance and dielectric properties of base resin. It shows good compatibility with PC, PA, PPO and epoxy resin, no obvious blooming under normal dosage. It can help finished products reach UL94 V-0 flame rating at low loading.
