uv-326 is a benzotriazole type ultraviolet light absorber, impacting good light stability for plastics and other organic polymers. uv-326 is especially suited for polyolefins ad cold cured polyesters. it protects polymers from uv radiation helping to preserve the original appearance and physical integrity, especially for polyolefins and polyester resins.


Other names: TINUVIN 326; EVERSORB 73

Appearance: Light yellow powder

Solubility: Clear solution, free from insoluble

Liquescens punctum, 137-141

Volatiles content:0.5% max

Ash content: 01 % max

Transmittance: 460nm 96.0% min

500nm 97.0% min

UV-326 can be dissolved in such organic solvent such as benzol, touene, phenyethene, etc. It can not be dissolved in water. It can be easily dissolved in som kinds of resin, and it is not sensitive to metal Ions. Under alkalinity, as low volatile, it is not turned int yellow, ca absorb the ultraviolet ray of 270-380nm wavelength effectively. When used with antioxidants, it has cooperative effect. With lower position, it is considered as the world's sagest plastic accretion.
