Iyini i-UV-329 CAS 3147-75-9?

I-Absorption ye-UV-UV-329 iyi-ejenti enhle kakhulu futhi ephumelelayo yokulwa nokuguga, encibilika ku-benzene, styrene, ethyl acetate, encibilika kancane ku-ethanol, ayincibiliki emanzini, ingamunca ukukhanya kwe-UV okungu-270-340 nm, Isetshenziswa kakhulu ku-PE, PVCChemicalbook, PP, PS, fiber, i-polyposin resin ne-fiber i-vinyl acetate nezinye izici. Ingasetshenziselwa izinto zokupakisha ezifana neziqukathi zepulasitiki namabhokisi okupakisha okudla, ziwanikeze umphumela omuhle wokuzinzisa ukukhanya.

Isicelo

I-Light stabilizer i-UV-329 iyi-stabilizer yokukhanya esebenza kahle kakhulu enezinhlobonhlobo zezindawo zokumunca i-UV, ukuguquguquka okuphansi, kufanelekile i-polystyrene, i-polymethyl acrylate, i-polyester, i-polyvinyl chloride eqinile, i-polycarbonate, ama-ABS resins, njll. Isebenza ngokukhethekile emikhiqizweni esobala kanye namapulasitiki obunjiniyela acutshungulwa ezingeni lokushisa eliphezulu. Uma ihlanganiswe ne-antioxidant, inomphumela omuhle kakhulu we-synergistic, ongathuthukisa ukumelana nesimo sezulu kanye nokuzinza kokushisa komkhiqizo.
