Tinuvin® 234 P

Technical Datasheet | Supplied by BASF
HSP Distance with UV-360 (MFCI): 3.4
Tinuvin® 234 P by BASF is chemically phenol, 2-(2H-benzotriazol-2-yl)-4,6-bis(1-methyl-1-phenylethyl) grade. Acts as a UV absorber. It is a high molecular weight product belonging to hydroxyphenyl benzotriazole class. Imparts excellent light stability to a variety of polymers. Features low volatility, exceptional light absorbing characteristics and good compatibility in various substrates. This makes the product particularly suitable for applications characterized by high surface area, such as films and fibers. Suitable for polycarbonates, polyalkylene terephthalates, polyacetals, polyamides, polyphenylene sulfide, polyphenylene oxide, aromatic copolymers, thermoplastic polyurethane and polyurethane fibers, as well as for polyvinylchloride, styrene homo- and copolymers. Applications include molded articles, films, sheets and fibers. Use levels of Tinuvin® 234 P ranges between 0.15 and 0.60%, depending on substrate and performance requirements of the final application.
