Chemical name: N,N-bis(2,2,6,6-tetramethyl-4-piperidyl)-N,N diformylhexamethylenediamine CAS No 124172-53-8 Molecular formula:Â C26H50N4O2 Molecular weight: 450 Molecular structure Specification Appearance: White to off white crystalline powder Purity, %: 99 min. Loss on drying,%: 0.5 max. Melting point: 155-158 degree Application LIGHT STABILIZER LS-4050 is a low molecular weight hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. It provides excellent light stability for thick sections but can also be used for articles with a high surface area such as films and tapes. It is suitable for the stabilization of polyolefins, particularly in thick-walled PP molding and PP fibers, as well as ABS, PS, PA and polyesters.It is highly compatible with pigments.
