Flame retardant

This article is about chemical flame retardants used in textiles, plastics and resins. For chemicals used to fight structure fires and wildfires, see Fire retardant.

Open-flame tests compare the flammability of untreated polyurethane foam (top) and an identical foam sample surface treated with a sandwich-like coating incorporating layered double hydroxides. By 90 seconds after ignition the untreated foam is completely consumed.

The term flame retardant subsumes a diverse group of chemicals that are added to manufactured materials, such as plastics and textiles, and surface finishes and coatings.[1] Flame retardants are activated by the presence of an ignition source and prevent or slow the further development of flames by a variety of different physical and chemical mechanisms. They may be added as a copolymer during the polymerisation process, or later added to the polymer at a moulding or extrusion process or (particularly for textiles) applied as a topical finish.[2] Mineral flame retardants are typically additive, while organohalogen and organophosphorus compounds can be either reactive or additive.
