The recent progress on some halogen-free flame retardants for polypropylene, such as aluminummagnesium flame retardants, intumescent flame retardants, phosphorus-containing flame retardants, and silicon-based flame retardants, is reviewed. The effects of halogen-free retardants on the flame retardancy and mechanical properties are analyzed and the problems yet to be solved in science and technology are summarized for halogen-free flame retarded polypropylene. A research thought is put forward for preparing halogen-free flame retarded polypropylene with excellent flame retardancy and good mechanical properties by studying synergism between different flame retardants, preparing new surface modifiers, and developing new surface modification technology to improve compatibility between flame retardants and polypropylene and form moderate flexible and strong bonding interface.
