Flame Retardants

Boric acid inhibits the release of combustible gases from burning cellulosic materials, such as cotton, wood, and paper-based products. Boric acid also releases chemically bonded water to further reduce combustion. A carbon char is formed that further inhibits combustion. Futons, mattresses, upholstered furniture, insulation, and gypsum board are common consumer items that use boric acid as a flame retardant. Plastics, textiles, specialty coatings, and other industrial products also contain boric acid to strengthen their ability to withstand exposure to flames.
