Product Description

Ultraviolet absorbent UV-  783
 
 
Characterization                               
 UV 783 is a synergistic mixture of light stabilizer 944 and LS622. It is a versatile light stabilizer with good extraction resistance, low gasfading and low pigment interaction. UV 783 is particularly well suited for LDPE, LLDPE, HDPE films, tapes and thick sections and for PP films. It is also the product of choice for thick sections where indirect food contact approval is required.
