Yini i-Octabenzone CAS 1843-05-6?

I-UV-531 ingeyesigaba se-benzophenone sezidonsa ze-ultraviolet, negama lekhemikhali elithi 2-hydroxy-4-n-octyloxybenzophenone. Iyimpushana ekhanyayo enaliti ephuzi emise okwekristalu ekushiseni kwegumbi futhi iyi-ejenti eqeda ukuguga enhle kakhulu futhi esebenza kahle ekwazi ukumunca ukukhanya kwe-ultraviolet. Inezici zombala okhanyayo, ukungabi nobuthi, ukuhambisana okuhle, ukuhamba okuphansi, nokucubungula kalula. Isetshenziswa kabanzi ku-PE PVC, PP, PS, PC, ingilazi ye-Organic, i-polypropylene fiber, ne-ethylene vinyl acetate.
