Other Non‐Halogenated Flame Retardants and Future Fire Protection Concepts & Needs

In the pursuit of non-halogenated flame retardant solutions, there are large swaths of the periodic table which have not been fully studied for their flame retardant potential. In this chapter, these other elements are discussed including known flame retardant effects of transition metals, sulfur compounds, and tin compounds. Carbon based flame retardant solutions including cross-linking chemical groups, carbonates, and bio-based materials are also discussed. Some discussion on engineering solutions based upon metal and chemical coatings which enable non-halogenated flame retardancy is included as well in this chapter. Finally, thoughts on future directions in non-halogenated flame retardancy, especially experimental design and environmental considerations, conclude the chapter.
