Product Name:Light Stabilizer 944
English Name:Light Stabilizer 944
CAS No.:71878-19-8
Aliases:Hindered Amine Light Stabilizer 944, GW-944, 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]]
Molecular Formula:C35H69Cl3N8
Physical Properties:White to light yellow granular powder. Melting point approximately 100-135°C. Loose density 0.45-0.55 g/cm³. Insoluble in water, soluble in toluene, xylene, chloroform and other organic solvents. Exhibits excellent thermal stability, extraction resistance and good compatibility with polymers.
Uses:Primarily used as a light stabilizer for polyolefins such as polypropylene and polyethylene, as well as styrenics and polyester materials. It effectively absorbs UV radiation and quenches excited states, significantly inhibiting photo-oxidative degradation of polymers and extending the service life of products in outdoor environments.
Technical Specifications:
Appearance: White to light yellow granules or powder
Active content: ≥99%
Melting point: 100-135°C
Volatile content: ≤0.5%
Solubility: Insoluble in water, soluble in toluene, xylene and other organic solvents
