Benzophenone-12 Synonyms: UV-284 

Benzophenone-12 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.

Benzophenone-12 Property : 

Yellowish crystals; 
Yellowish fine powder 
Freely soluble in benzene, n-hexane, acetone, slightly soluble in ethanol, very slightly soluble in ethane dichloride.
Specification                     
Content:≥99 % 
Melting Point: 47~49 °C 
Ash: ≤0.1 %
Light Transmittance: (450nm)≥90%   (500nm)≥95%

Appearance: white to yellowish powder

 

Benzophenone-12 Applications

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

Benzophenone-12 Storages:
The product may be stored up to two years in a sealed container. Containers should be stored in a cool, dry area. Extended storage at elevated temperatures or exposure to direct heat or sunlight could reduce product life. Keep containers sealed when no in use.
