Product Name:Light Stabilizer LS-144
English Name:Light Stabilizer LS-144
CAS No.:63843-89-0
Aliases:Bis(1,2,2,6,6-pentamethyl-4-piperidyl) 2-butyl-2-(3,5-di-tert-butyl-4-hydroxybenzyl)malonate, Tinuvin 144
Molecular Formula:C42H72N2O5
Physical Properties:It appears as a white to pale yellow crystalline powder, with a melting point of 146–150°C and a density of about 1.1 g/cm³ at 20°C. It is insoluble in water and soluble in most organic solvents such as toluene, ethyl acetate, and acetone; it has low volatility and good thermal stability.
Uses:LS-144 is a combined light stabilizer with both hindered amine light stabilizer (HALS) and hindered phenol antioxidant functions. It is widely used in polypropylene, polyethylene, polystyrene, as well as polyurethane, coatings, and adhesives, effectively inhibiting photodegradation and thermo-oxidative aging, significantly extending the service life of outdoor products.
Technical Specifications:
Appearance: white to pale yellow crystalline powder.
Assay (as C42H72N2O5) ≥ 98%.
Melting point: 146–150°C.
Volatile content ≤ 0.5%.
Ash content ≤ 0.1%.
