Pali magulu ambiri a mankhwala omwe amagwiritsidwa ntchito ngati zoletsa moto.Ngakhale pano ndi gawo laling'ono la msika waukuluwu, Magnesium Hydroxide ikukopa chidwi chifukwa cha magwiridwe ake, mtengo wake, kuwononga pang'ono, komanso kawopsedwe kakang'ono.Msika wapano wa magnesium hydroxide mu zoletsa moto ndi pafupifupi mapaundi mamiliyoni khumi pachaka, ndi kuthekera kopitilira mapaundi mamiliyoni makumi atatu pachaka posachedwa.
Mg(OH)2 imagwiritsidwa ntchito ngati FR muzamalonda zamafakitale ku United States komanso muzamalonda ndi mipando yaku United Kingdom (Fire Retardant Chemicals Association 1998).Kukhazikika kwa Mg(OH)2 pa kutentha pamwamba pa 300 ° C kumapangitsa kuti ikhale ndi ma polima angapo (IPCS 1997).Deta ya kuchuluka kwa msika yomwe idasindikizidwa mu 1993 ikuwonetsa kukulitsa kugwiritsa ntchito Mg(OH)2 ngati FR.Pafupifupi matani 2,000 ndi 3,000 a Mg(OH)2 adagulitsidwa ngati FR ku United States mu 1986 ndi 1993, motsatira (IPCS 1997).
Magnesium hydroxide (Mg(OH)2), ndi asidi- ndi halogen-free lawi retardant kwa mapulasitiki osiyanasiyana.Magnesium hydroxide ili ndi kutentha kwapamwamba kwa 100oC kuposa ATH, kulola kutentha kwapamwamba pakuphatikiza ndi kutulutsa pulasitiki.Komanso, magnesium hydroxide imatulutsa mphamvu zambiri panthawi ya kuwonongeka.
Magnesium hydroxide imagwira ntchito ngati chotchingira moto komanso chopondereza utsi m'mapulasitiki makamaka pochotsa kutentha kwa pulasitiki pakuwonongeka kwake kukhala magnesium oxide ndi madzi.Mpweya wamadzi womwe umapangidwa umachepetsa mafuta omwe amafika pamoto.Zinthu zowola zimatsekereza pulasitiki kuti isatenthedwe ndipo imatulutsa moto womwe umalepheretsa kutuluka kwa mpweya womwe ungayake kupita kumoto.
Kuti chowotcha moto chikhale chothandiza mu mapulasitiki ophatikizana, sichiyenera kutsitsa mawonekedwe apulasitiki.Mu mawonekedwe osinthika a waya a PVC, ZEHUI CHEM' idapezeka kuti imasintha pang'ono mawonekedwe a PVC poyerekeza ndi ATH komanso mpikisano, wapamwamba kwambiri wa magnesium hydroxide.
