Product Description

Benzophenone UV Absorber UV-531 

Other names: UV stabilizer BP-12 (Benzophenone-12); Chimassorb 81; UV531; UV 531; Lowilite 22; Eversorb12; 3008; UV absorbent 531; Ultraviolet light absorber UVA 531; Benzotriazole UV absorber 531

Chemical name : 2-Hydroxy-4-n-octoxybenzophenone

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.
