GENERAL DESCRIPTION OF FLAME RETARDANT AGENT
Flame Retardant are substances that can be chemically inserted into the polymer molecule or be phisically blended in polymers after polymerization to suppress, reduce, delay or modify the propagation of a flame through a plastic materials. There are several classes of flame retardants; Halogenated Hydrocarbons (Chlorine and Bromine containing compounds and reactive flame retardants), Inorganic flame retardants ( Boron compounds, Antimony oxides, Aluminium Hydroxide, molybdenum compounds, zinc and magnesium oxides ), Phosphorous containing compounds (Organic phosphate esters, phosphates, halogenated phosphorus compounds and inorganic phosphorus containing salts). Class of Flame Retardants Inorganic Metal hydroxides Aluminium hydroxide Magnesium hydroxide Orthers Antimony compounds Antimony trioxide antimony pentoxide Sodium antimonate Others Boron compounds Boric acid Borax Zinc borate Others Other metal compounds Molybdenum compounds Titanium compounds Zirconium compounds Zinc compounds Zinc stannate Zinc hydroxy-stannate Others Others Phosphorus compounds Red phosphorus Ammonium polyphosphate Others Other inorganic flame retardants ammonium sulfamate ammonium bromide Others Halogenated organic Brominated Tetrabromobisphenol A Decabromodiphenyl ether Octabromobiphenyl ether Tetrabromobiphenyl ether Hexabromocyclododecane Tribromophenol Bis(tribromophenoxy) ethane Tetrabromobisphenol A polycarbonate oligomers Tetrabromobisphenol A epoxy oligomers Others Chlorinated Chlorinated paraffins Bis(hexachlorocyclopentadieno)cyclo-octane Others Organophosphoros Non-halogenated compounds phosphate esters Ttrialkyl phosphates Triaryl phosphates Aryl-alkyl phosphates Others polyols phosphonium derivatives phosphonates Others Halogenated phosphates Tris(1-chloro- 2-propyl) phosphate Tris(2-chloroethyl) phosphate Tris(2,3-dibromopropyl)phosphate Others Nitrogen-based Polyurethanes Polyamides Melamine and its salts Guanidine compounds Others
OTHER INFORMATION
Antimony trioxide and pentoxide don't react as flame retardants directly. They are used as synergists to enhance the activity of halogenated flame retardants by stepwise releasing the halogenated radicals to retard gas phase chain reaction of flame spread.
