Application

LS-770 is a low molecular weight hindered amine light stabilizer, with low volatility, migration resistance, and high temperature resistance. It has synergetic effect with antioxidants and UV absorbers.

It is suitable for polyolefin materials, cross-linked polyethylene, olefin copolymers and other polymer materials. It can often be used with other light stabilizers, antioxidants and UV absorbers, to further improve the anti-aging effect of materials.
