Research Progress of Flame Retardant Polypropylene Composites
This paper introduced the background and application of flame retardant polypropylene.The flame-retardant mechanism was also described briefly.The research progress of polypropylene composites was reviewed from from two aspects,such as halogen-containing and halogen-free flame retardants.Finally,the trend of further research about flame-retarded polypropylene was summarized.
