V Absorber 326 Usage And Synthesis
Characterization    UV Absorber 326 is a UV absorber of the hydroxyphenylbenzotriazole class, which imparts outstanding light stability to plastics and other organic substrates.
Features/Benefits    UV Absorber 326 has a wide range of indirect food approvals in polyolefins. 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 the polyolefin compounding and molding processes. In the use for the UV protection of polyester resins, TINUVIN 326 does not form colored complexes with the metallic salts used for the curing process of these resins.
Applications    UV Absorber 326 is especially suited for polyolefins and cold cured polyesters.
Chemical Properties    Pale Yellow Solid
Uses    Bumetrizole is an intermediate reactant in the synthesis of UV light absorbers for polyester fibers.
