Abstract: This paper briefly introduced elemental hybridization technologies for flame-retardant polypropylene (PP) and also discussed its combustion mechanism including heat, decomposition and ignition of PP and flame-retarding methods containing gas phase, condensed phase and interrupting heat exchange. Research progresses in elemental flame-retardant mechanisms, synergistic flame-retardant PP and bio-based flame retardants were overviewed. The paper also summarized problems in current researches of flame-retardant PP and proposed its direction of future development.
