Hindered amine light stabilizers tapes

For example, a high MW hindered amine (eg, CYASORB UV-3346 Light Stabilizer) combined with CYASORB UV-2908 provides synergistic performance in PP slit tape applications during Xenon ARC WOM exposure (Fig. 11) (64). The use of this combination also allows improved processability in production of the slit tapes because of reduction in water carryover compared with HALS alone. It has also been demonstrated that, in thick section PP, long-term stability can be dramatically improved with CYASORB UV-3346 combined with CYASORB UV-2908.
