Octabenzone CAS 1843-05-6 (UV Absorber UV-531; Benzophenone-12) Purity>99.0% (HPLC)

2-Hydroxy-4-n-Octyloxybenzophenone (Octabenzone; UV Absorber UV-531; Benzophenone-12) (CAS: 1843-05-6) ndi ultraviolet kuwala absorber (UVA) wa kalasi benzophenone, kupereka bwino kuwala bata mapulasitiki ndi ma polima ena organic.Chifukwa cha mphamvu zake zoyamwitsa za UV komanso zogwirizana kwambiri ndi polima, UV-531 imapereka chitetezo chokwanira cha polima komanso kutsika kwamitundu, imachepetsa chikasu ndi kuwonongeka kwa thupi.UV531 ndiwotulutsa bwino kwambiri wa ultraviolet wokhala ndi kusinthasintha kochepa, kukana kusamuka komanso kuwongolera kosavuta.Imakhala ndi ma synergistic effect ndi antioxidant ndi kuwala stabilizer.UV Absorber UV-531 ndi stabilizer kuwala ndi ntchito zabwino, amatha kuyamwa UV kuwala kwa 240-340 nm wavelength ndi makhalidwe a kuwala mtundu, nontoxic , ngakhale zabwino, kuyenda yaing'ono, processing zosavuta etc. Ikhoza kuteteza polima kuti Kuchuluka kwake, kumathandiza kuchepetsa mtundu.Ikhozanso kuchedwetsa chikasu ndikulepheretsa kutaya kwa thupi lake.Amagwiritsidwa ntchito kwambiri ku Pe, PVC, PP, PS, PC organic galasi, polypropylene CHIKWANGWANI, ethylene-vinyl acetate etc. Komanso, ali ndi zabwino kwambiri kuwala-bata zotsatira kuyanika phenol aldehyde, vanishi mowa ndi acname, polyurethane, acrylate. , expoxnamee etc.. Mlingo wovomerezeka ndi 0.1% --0.5%.UV-531 UV-Absorber imagwira ntchito ngati choyatsira UV, imapeza ntchito popanga zodzoladzola zamtundu ndi tsitsi, dzuwa ndi zosamalira thupi.Mlingo wake ndi 0.1% -0.5%.1. Polypropylene : 0.2-0.5wt% yotengera kulemera kwa polima2. PVC:PVC yolimba: 0.5wt% kutengera kulemera kwa polima.Pulasitiki PVC: 0.5-2 wt% kutengera kulemera polima.
