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.
