Detailed Description

 RFCUV-531(Benzophenone UV Absorber )

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.

Molecular formula: C21H26O3
Structure :

Appearance : light yellow powder  Melting Range : 47-49 °C

Transmittance (%) : 440nm≥97  500nm≥98


1.Polypropylene : 0.2-0.5wt% based on polymer weight

2.PVC:Rigid PVC : 0.5wt% based on polymer weight

Plasticized PVC : 0.5-2 wt% based on polymer weight

3.Polyethylene : 0.2-0.5wt% based on polymer weight
Packing:UV-531 is available in powder form in a  25kg fiber drum with an inner PE liner or 25kg carton.
