UV326 yog UV abreatber ntawm 300nm, nrog lub teeb zoo stabilization nyhuv, hloov lub teeb ci ultraviolet los ntawm photochemical nkaus; Cov khoom tau nqus tau ntau dua ntawm kev nqus tau ntev ntev, zoo sib xws nrog polyolinas, qis volatilization thiab inhibiting phenol ionization; Cov khoom muaj cov alkaline zoo thiab yuav tsis ua rau xim hloov vim muaj hlau. Vim nws lub siab ionization tas li, cov neeg sawv cev hlau, catalyst ntawm nws cov cawv qis; Nyob rau hauv cov khoom sab nraum zoov, tuaj yeem siv nrog phenolic antioxidant thiab phosphite antioxidant.
Nws yog tsuas yog siv nyob rau hauv polyvinyl chloride, polystyred, unsaturated cob, polymelylene, polyethylene, Abs cob, ABS Resin, Apoxy Resin thiab lwm yam.
Pom zoo tus nqi: 0.1% -1.0%, cov nyiaj tshwj xeeb yog txiav txim raws li cov neeg siv khoom thov
