HPCTP, chemical name hexaphenoxycyclotriphosphazene, CAS 1184-10-7, is halogen-free cyclic phosphazene flame retardant and direct equivalent to SPB-100. It adopts phosphorus-nitrogen synergistic flame retardant mechanism. It has excellent thermal stability and low volatility, suitable for high-temperature processing of engineering plastics and epoxy resin systems. This grade is developed as drop-in replacement for SPB-100, compatible with existing formulation processes for PC, nylon, PPO and cop
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: SPB-100 equivalent halogen-free phosphazene for PC, Nylon, PPO and CCL
Key Performance & TDSHPCTP is fully interchangeable with SPB-100 in polymer formulations. The phosphorus-nitrogen synergistic system forms dense protective char layer under fire, blocking heat and oxygen transfer. It has high decomposition temperature, resisting thermal degradation and foaming during extrusion, injection molding and epoxy curing. It is halogen-free and releases low smoke with no corrosive halogen gas on combustion. It maintains good mechanical properties, dielectric performance and surface quality of substrates. It shows excellent compatibility with PC, PA, PPO and epoxy resin, no blooming or precipitation at recommended dosage. It helps finished products achieve UL94 V-0 rating as SPB-100 does.
