LS-2020 is a high molecular weight hindered amine light stabilizer (HALS). It shows excellent polymer compatibility and high extraction resistance. One of the unique features of LS-2020 is a very narrow molecular weight distribution, resulting in a consistent performance in use and processing. LS-2020 combines the typical benefits of a variety of high molecular weight HALS. It provides superior light/thermal stability to polymers and improved ancillary properties like improved polymer processing.
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.
