HPCTP, chemical name hexaphenoxycyclotriphosphazene, CAS 1184-10-7, is halogen-free cyclic phosphazene flame retardant specially formulated for PA6 and PA66 nylon engineering plastic. It adopts phosphorus-nitrogen synergistic flame retardant mechanism and delivers high flame retardant efficiency at low loading. It features excellent thermal stability to withstand high temperature extrusion and injection molding processing of nylon. It minimizes negative impact on tensile strength, impact resista
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 with low loading for PA6 PA66 engineering plastic
Key Performance & TDSHPCTP relies on phosphorus-nitrogen synergistic effect to form compact char barrier on nylon surface upon exposure to flame, cutting off heat and oxygen transfer and suppressing melt dripping. It has high thermal decomposition temperature, stable during nylon high-temperature compounding and molding without decomposition or foaming. Low dosage requirement reduces formula cost and retains original mechanical performance of PA6 and PA66. Halogen-free composition generates low smoke and no corrosive halogen gas in fire events. It exhibits good compatibility with nylon matrix, no migration or blooming under recommended addition amount. It helps PA6 and PA66 molded parts pass UL94 V-0 vertical burning test.
