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 Weight : 326
Appearance : light yellow powder
Melting Range : 47-49 degree
Assay : 99% Min.
Volatile Matter : 0.5% Max.
Specific Gravity(20 degree) : 1.16g/cm3
