Light Stabilizer 622

Chemical Name: Butanedioic acid polymer with(4-hydroxy-2,2,6,6-tetramethyl-
1-piperidineethanol)
Properties:
It is white or light yellow grain solid. The content of available nitrogen is 4.9%. Its softening temperature is 55~800C. The relative density is 1.18(200C). The heat loss of 1% is 2750Cand 10% is 3250C. This product is an oligomer with good process heat stability and has good compatibility with resin. It is water-fast, and is effective to prevent the degradation of high polymer caused by light, heat and weather, water.
