UV STABILIZER 944 (CAS NO:71878-19-8)

UV Stabilizer 944 is a polymeric hindered amine light stabilizer (HALS) known for its high molecular weight, excellent extraction resistance, and low volatility. It offers long-term protection against UV degradation, particularly in polyolefins, elastomers, and engineering plastics. This stabilizer is effective in both thick-section and thin-section applications, making it widely used in outdoor and high-performance polymer applications. Also known as chimassorb@944, HALS 944. Also it carries as 70624-18-9(USA) as cas number. It generally has chemical name as N,N'-bis(2,2,6,6-tetramethylpiperidin-4-yl)hexane-1,6-diamine; 2,4,6-trichloro-1,3,5-triazine; 2,4,4-trimethylpentan-2-amine Poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-1,3,5-triazine-2,4- diyl][(2,2,6,6-tetramethyl-4-piperidyl)imino]hexamethylene[(2,2,6,6- tetramethyl-4-piperidyl)imino]] Polymeric sterically hindered amine light stabilser.
