Yintoni i-Octabenzone CAS 1843-05-6?

I-UV-531 ikwiklasi ye-benzophenone yee-ultraviolet absorbers, enegama lekhemikhali elithi 2-hydroxy-4-n-octyloxybenzophenone. Yipowder yekristale etyheli ekhanyayo kwiqondo lobushushu begumbi kwaye yiarhente ebalaseleyo nesebenzayo yokulwa nokwaluphala enokufunxa ukukhanya kwe-ultraviolet ngamandla. Ineempawu zombala okhanyayo, ukungabi natyhefu, ukuhambelana okuhle, ukuhamba okuphantsi, kunye nokucutshungulwa okulula. Isetyenziswa kakhulu kwi-PE PVC, PP, PS, PC, iglasi yendalo, i-polypropylene fiber, kunye ne-ethylene vinyl acetate.
