Yini i-Light Stabilizer-944 CAS 70624-18-9?

I-stabilizer yokukhanya i-UV-944 inokumelana okuhle kokukhipha, kulungele ikakhulukazi imikhiqizo emincane, njengemicu namafilimu; Kungathuthukisa futhi ukumelana nokuguga kwe-oxygen eshisayo yezinto ezibonakalayo. I-stabilizer yokukhanya i-HS-944 imhlophe kuya kwezinhlayiya eziphuzi ezikhanyayo noma i-powder, iphuzu lokuncibilika i-100-135 ° C, isisindo se-molecular 2000-3100, ngokuhambisana okuhle kakhulu, ukumelana nokukhipha kanye nokuguquguquka okuphansi. Njengoba i-UV-944 iyisilinganisi esiphezulu se-molecular mass stabilizer, futhi i-molecule iqukethe kuphela inani elikhulu le-methylate, izinzile uma iphathwa nge-oxygen eshisayo.
