Introduction : UV- 531 is an ultraviolet light absorber (UVA) of the benzophenone class, imparting good light stability for plastics and other organic polymers. Due to its highly effective broad UV absorption properties and excellent polymer compatibility, UV- 531 offers maximum polymer protection and low color contribution, retards yellowing and loss of physical properties.
Solubility At 20 ℃ (g/100ml solvent)

UV absorber uv-531 is an effective anti-aging agent with excellent performance. It can absorb ultraviolet light of 240-340 nanometers. It has the characteristics of light color, non-toxic, good compatibility, small migration and easy processing. It has the greatest protective effect on the polymer, and helps to reduce the color, while delaying yellowing and retarding the loss of physical properties. It is widely used in PE, PVC, PP, PS, PC, plexiglass, polypropylene fiber and vinyl acetate. And for dry phenolic and alkyd varnishes, polyurethane, acrylic, epoxy and other air drying products and automotive paint, powder coatings, polyurethane, rubber products, to provide them with a good light stability. The dosage of 0.1% to 0.5%. Packing: 25kg carton or carton packing.
