UV531 Light Absorber

 Chemical Name: 2-Hydroxy-4-octoxybenzophenone


 Application :
UV531 is effective in polyolefin, including low and high density polyethylene,polypropylene, olefin copolymers(EPR, EPDM, EVA), and other polymers including polyvinyl chloride, polye sters, natural and synthetic resins, polystyrene and ABS.



 



UV326 Light Absorber

 Chemical Name: 2-(5-chloro-2H-benzotriazole-2-yl)-6-(1,1-dimethylethyl)-4-methyl Phenol


 Application :
UV326 is especially suited for polyolefin and cold cured polyesters. It has a low volatility at high temperatures and high resistance to thermal degradation and can therefore be used without significant loss or decomposition in polyolefin compounding and molding processes. In the use for the UV protection of polyester, UV326 does not form colored complexes with the metallic salts used for the curing process of these



 

 UV327 Light Absorber

 Chemical Name: 2,4-di-tert-butyl-6-(5-chlorobenzotriazol-2-yl)-Phenol 


Application :UV327 is a highly effective light absorber for variety of plastics and other organic substrates. Due to its red shifted UV absorption, it is particularly suited for use in the stabilization of polymers that are especially sensitive to long-wavelength UV radiation (e.g. polyurethanes, polyphenylene sulfide) and in certain applications where very low transmission of long-wavelength UV radiation is required (e.g. optical lenses). Its use  recommended in a variety of polymers and organic substrates, including a crylic polymers, polycarbonate, polyesters ,styrene homo-andcopolymers, unsaturated polyesters, polyvinylchloride, polyolefins, polyvinylbutyral, elastomers and adhesives. 



 

UV328 Light Absorber

Chemical Name: 2-(2'-Hydroxy-3',5'-di-t-amylphenyl)benzotriazole 


Application :UV328 is a strong ultraviolet light absorber in the 290-400nm region. It provides dffective light stabilization and prevents the yellowing and degradation of polymers such as VC, unsaturated polyester, acrylics, ABS, thermoplastic urethanes, moisture cured polyurethanes, two component epoxies and urethanes, oil alkyds and thermosetting acrylic enamels.



 

UV329 Light Absorber

 Chemical Name: 2-(2H-benzotriazol-2-yl)-4-(tert-octyl) phenol 

Application :UV329 protects polymers from UV radiation, helping to preserve the original appearance and physical integrity of molded articles, films, sheets, and fibers during outdoor weathering.
