Introduction
There. are. four. main. types. of. lame. retardants:. chlorinated. lame. retar-
dants. (such. as. chlorinated. parafin. wax),. phosphoric. lame. retardants.
(such.as.phosphoric.esters),.inorganic.lame.retardants.(such.as.Mg(OH) 2 ,.
Al(OH) 2 ),.and.brominated.lame.retardants.(such.as.PBBs,.HBCD,.and.poly-
brominated.diphenyl.ethers.[PBDEs]).that.are.produced.on.a.global.scale..
The.brominated.lame.retardants.have.the.highest.eficiency.for.retarding.
lames,. at. a. lower. cost.. They. are. especially. suitable. for. organic. polymer.
products. and. are. widely. used. in. electrical. and. electronic. products. (Liu.
et.al..2005a).
