UV326 yog UV absorber ntawm 300-400nm, nrog zoo lub teeb stabilization nyhuv, converting ultraviolet lub teeb rau hauv tshav kub zog los ntawm photochemical kev txiav txim; Cov khoom muaj txiaj ntsig zoo dua ntawm kev nqus ntev ntev, zoo sib xws nrog polyolefin, tsis tshua muaj volatilization thiab inhibiting phenol ionization; cov khoom muaj zoo alkaline tsis kam thiab yuav tsis ua rau cov xim hloov vim hlau. Vim nws qhov siab ionization tsis tu ncua, hlau ziab tus neeg sawv cev, catalyst ntawm nws cov cawv tsawg; Hauv cov khoom siv sab nraum zoov, tuaj yeem siv nrog phenolic antioxidant thiab phosphite antioxidant.
Nws yog tsuas yog siv hauv polyvinyl chloride, polystyrene, unsaturated resin, polycarbonate, polymethyl methacrylate, polyethylene, ABS resin, epoxy resin thiab lwm yam.
Pom zoo tus nqi: 0.1% -1.0%, tus nqi tshwj xeeb yog txiav txim siab raws li cov neeg siv khoom thov kev xeem
Ntim hauv 20 lossis 25 Kg / carton.
Khaws rau hauv qhov chaw txias, qhuav thiab qhov cua; zam lub hnub ncaj qha.
