Poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-s-triazine-2,4-dinyl][(2,2,6,6-tetramethyl-4-piperidyl)imino] hexamethylene[2,2,6,6,-tetramethyl-4-piperidyl) imino]]. Acts as a polymeric hindered amine light stabilizer (HALS) of N-R type that protects polymers from degradation due to ultraviolet radiation and long term heat aging. Since there are many kind of organic function groups in its molecule, its light stability is very high. Because of large molecule weight, it possesses fine heat-resistance, drawing-standing, low volatility and well colophony compatibility. Can be applied to low density polyethylene, polypropylene fiber, glue belt, EVA ABS, polystyrene and foodstuff package etc.
