uv-328 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 328; EVERSORB 74
Appearance: Light yellow powder
Solubility: Clear solution, free from insoluble
Точка на топене: 79-87
Volatiles content:0.5% max
Ash content: 01 % max
Transmittance: 460nm 96.0% min
500nm 97.0% min
UV-328 is a light stabiizer with good performance, capabie of absorbing the UV radiation of 240-340nm wavelength with the characteristics of light color ,non-toxic, good compatibility, small mobility, easy processing etc. It can protect the polymer to its maximum extent, helps to reduce the color. It can also delay the yelowing and obstacle the loss of its physical function. It is widely applied to PE, PVC, PP, PS, PC, Organic glass, polypropylene fiber, ethylene-vinyl acetate etc. Moreover, it has very good light-stability effect pn drying phenol aldehyde, vanish or alcohol and acname, polyurethane, acrylate, expoxnamee etc.
