Intrinsic flame retardant epoxy resins, including silicon-containing and special structural epoxy,resins were overviewed. Compared with traditional additive flame retardant systems, halogenand phosphorus-epoxy resins, silicon-containing and special structural epoxy resins gave rise to better flame retarding performance, higher physical properties, and could be seen as green flame retarding systems. In addition, a better flame retardancy of epoxy resins could be achieved through use of synergistic effects. However, complex synthetic routes and higher cost had limited the wide application of such systems.
