Flame retardant
From Free net 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 PBDEs, 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 textile ("Proban").
Other flame retardants are eg. chlorinated paraffins, polybrominated biphenyls (PBB), penta-bromodiphenyl ether (pentaBDE), octa-bromodiphenyl ether (octaBDE), tri-o-cresyl phosphate, tris(2,3-dibromopropyl) phosphate (TRIS), bis(2,3-dibromopropyl) phosphate, tris(1-aziridinyl)-phosphine oxide (TEPA), and others.
