In this work, a flame retardant system consisting of P-N intumescent flame retardant (IFR), melamine phosphate, ammonium polyphosphate (APP) and polytetrafluoroethylene (PTFE) was applied to polypropylene (PP). The IFR/APP/PTFE flame-retardant system showed significant synergistic effect, and the PP/IFR/APP/PTFE can reach a LOI value of 30.1% and UL-94 V-0 with only 24wt% flame-retardant (APP: 6wt%, IFR: 17.5wt%, PTFE: 0.5wt%). By using FTIR, SEM and XPS, the burning process of flame-retardant PP and the components of residual char were analyzed, and the flame retardant mechanism of PP/APP/IFR/PTFE system was studied.
