Halogen pawg Ⅶ cov khoom tsis yog xim hlau, suav nrog fluorine-, chlorine, bromine, iodine, astatine thiab tennessine, suav nrog halogens. Astatine yog cov khoom siv hluav taws xob, thiab halogens feem ntau hu ua fluorine, chlorine, bromine thiab iodine. Halogen compounds feem ntau yog siv los ua cov nplaim hluav taws kub: PBB, PBDE, TBBP-A, PCB, hexabromododecane, tribromophenol, luv saw chlorinated paraffin, thiab lwm yam. lawv yog siv rau hauv cov khoom siv hluav taws xob thiab cov khoom siv, cov khoom siv plhaub, yas, thiab lwm yam. nplaim retardants muaj xws li chlorine nplaim retardants, bromine nplaim retardants, polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs), tetrabromobisphenol-A (TBBP-A), hexabromocyclododecane (HBCD) thiab lwm yam. Chlorinated pob zeb (c10-13, SCCP) chlorinated alicyclic hydrocarbon tetrachlorophthalic anhydride (TCP) lwm cov halogen compounds polychlorinated biphenyls (PCBs): emollients, capacitor roj, polychlorinated naphthalene (PCNs): emollients, polyphenyls, preservatives emollients, preservatives.
Cov nplaim hluav taws ntxiv rau GPO-3 daim ntawv feem ntau yog txhuas hydroxide. Aluminium hydroxide yog non-toxic, tsis muaj halogen, thiab tsis tsim cov khoom corrosive. Cov no yog cov yam ntxwv ntawm nws siv. Tsis tas li ntawd, vim li cas nws thiaj li nrov yog tias nws tau siv dav thiab ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Nyob rau hauv lub Unsaturated Poly (vinyl acetate) cam khwb cia yas reinforced los ntawm fiberglass (xws li ntau yam high-voltage los yog low-voltage hluav taws xob hloov), aluminium nitride yog siv los ua ib tug muab tub lim los ua cov khoom yas muaj kev poob siab, tshem tawm cov pa taws thiab arc tsis kam. Aluminium hydroxide kuj tseem siv hauv FRP laminates.
