1) The list of halogen-free flame retardants is not complete, but indicates flame retardants in known commercial products cf. chapter 7. For some specific applications the flame retardants may not be immediately useful.
2) Alternative materials are only mentioned where no flame retardants grades of the material are commercially available, or where alternative materials actually are chosen in order to substitute BFRs.
