Flame Retardant PA6 Fiber Prepared by Co-addition of a Cyclic Diphosphonate Ester and Melamine
A commercial cyclic diphosphonate ester (TPMP) and melamine (MA) was combined and loaded to polymide 6 (PA6) to prepare the fire retardant PA6. An increase of the oxygen index to 28.6 as well as an improvement of the UL-94 classification to V-0 rating was observed. Cone measurements explained the rate of heat release (RHR) decreased. TGA displayed the early decomposition and high solid residue due to co- addition of TPMP and MA, suggesting the occurance of synergistic effect of TPMP and MA on fire resistance of PA6. The morphology of the charred residua developed during combustion showed the appearance of thick, intumescent cells on the surface of retardant PA6, which protects the underlying material from the action of the heat flux or flame and limits the diffusion of combustible volatile products towards the flame and oxygen.
