LS-4050

Low molecular weight hindered amine light stabilizer (HALS)

Description

LS-4050 is a low molecular weight hindered amine light stabilizer (HALS) for thermoplastics and elastomers, in particular for applications demanding high light stability (e.g. styrenic polymers and PP). It provides excellent light stability for articles with a high surface area such as films and tapes, as it’s not dependent on the polymer’s thickness.

Chemical name:

N,N'-1,6-hexanediylbis(N-(2,2,6,6-tetramethyl-piperidin-4-yl)formamide

Molecular formula:

C26H50N4O2

Molecular weight:

450 g/mol

CAS number:

124172-53-8

EC number:

413-610-0

Applications

LS-4050 is recommended to be used in polystyrene, impact polystyrene, ABS, SAN, ASA, polypropylene, impact modified PP (TPO), EPDM, and in polyamides. Due to its low volatility, LS-4050 is unique for high temperature processes compared to other low molecular weight HALS.
