UV-531 is a light stabilizer with good performance, capable of absorbing the UV radiation of 240-340nm wave langth 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 aso delay the yellowing 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 on drying phenol aldehyde,vanish of alcohol and acname, polyurethane, acrylate, expoxamee etc.
