What is Light Stabilizer 770 CAS 52829-07-9？
Among the world’s first hindered amine light stabilizer products born in the 1970s, light stabilizer 770 is the only hindered amine product still used in the contemporary plastics industry. Light stabilizer 770 can effectively absorb ultraviolet light at 290-400nm wavelength, or can quencher the energy of excited molecules, or has the ability to trap free radicals. The light stabilizer 770 has good photostability and thermal stability. Light stabilizer 770 has good compatibility and does not leak during use. Light stabilizer 770 is resistant to hydrolysis, low volatility, low pollution, non-toxic or low toxicity, cheap and easy to obtain.

Application
Light stabilizer 770 is suitable for polypropylene, high-density polyethylene, polyurethane, polystyrene, ABS resin, etc., 770 light stabilization effect is better than the current common light stabilizer. When used with antioxidants, it can improve heat resistance, and when used with ultraviolet absorbers, it also has a synergistic effect, which can further improve the light stabilization effect.
Packaging
