Material Notes:
UV 234 is a high molecular weight ultraviolet light absorber (UVA) of the hydroxyl phenyl benzotriazole class, imparting outstanding light stability to polymers usually processed at high temperatures such as polycarbonate, polyesters, polyacetal, polyamides, polyphenylene sulfide, polyphenylene oxide, aromatic copolymers, thermoplastic polyurethane and polyurethane fibers, where loss of UVA is not tolerated as well as for polyvinylchloride, styrene homo- and copolymers. Applications include molded articles, films, sheets and fibers.UV 234 has world wide Food Contact Approvals in most polymers and is especially suitable in packaging applications for food, consumer care products and pharmaceuticals.Chemical Name: 2-(2H-benzotriazol-2-yl)-4,6- bis(1-methyl-1-phenylethyl) phenolCAS No. 70321-86-7All information provided by Hongkun Group
