HPCTP, chemical name hexaphenoxycyclotriphosphazene, CAS 1184-10-7, is halogen-free cyclic phosphazene flame retardant customized for copper clad laminate and epoxy resin system. It adopts phosphorus-nitrogen synergistic flame retardant mechanism, featuring excellent thermal stability and low volatility. It can maintain good dielectric property, high glass transition temperature and thermal resistance of CCL substrate during lamination and soldering processes. It mixes well with epoxy resin and
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: Halogen-free phosphazene for copper clad laminate and epoxy resin
Key Performance & TDSHPCTP forms dense char layer on epoxy surface when exposed to flame, blocking heat and oxygen transfer to stop flame propagation. It has high thermal decomposition temperature, stable under high temperature prepreg drying, pressing and reflow soldering without decomposition or bubble generation. Halogen-free composition releases low smoke and no corrosive halogen gas in fire. It preserves dielectric constant, insulation performance and Tg value of CCL substrates, which is critical for PCB application. Fine powder ensures uniform dispersion in epoxy resin prepreg system, no precipitation during resin storage. It helps copper clad laminate products achieve UL94 V-0 flame retardant standard.
