Feather of Light Stabilizer 770
Light Stabilizer 770 is a low molecular weight hindered amine light stabilizer that provides
excellent light stability for thick sections and films in the recommended substrates.Benefits
of using LS770 is the high light-stabilizing performance,particularly in PP thick sections.
It has broad compatibility and can be easily dispersed. Compared to conventional UV-absorbers,
the effectiveness of LS770 is less dependent on the polymer's thickness.For this reason the use
of LS770 also provides good light stability in articles with higher specific surface,e.g.films and tapes.
