Flame retardant
From Wikipedia, the free encyclopedia
Flame retardants are materials that inhibit or resist the spread of fire. Naturally occurring substances such as asbestos as well as synthetic materials, usually halocarbons such as polybrominated diphenyl ether (PBDEs), polychlorinated biphenyls (PCBs) and chlorendic acid derivates, most often dibutyl chlorendate and dimethyl chlorendate, have been used in this capacity.
Tetrakis(hydroxymethyl) phosphonium salts, made by passing phosphine gas through a solution of formaldehyde and a mineral acid such as hydrochloric acid, are used as flame retardants for textiles.
Other flame retardants include chlorinated paraffins, polybrominated biphenyls (PBB), penta-bromodiphenyl ether (pentaBDE), octa-bromodiphenyl ether (octaBDE), deca-bromodiphenyl ether (decaBDE), hexabromocyclododecane (HBCD), tri-o-cresyl phosphate, tris(2,3-dibromopropyl) phosphate (TRIS), bis(2,3-dibromopropyl) phosphate, tris(1-aziridinyl)-phosphine oxide (TEPA), and others.
