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-770 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.
UV-234 is a high molecular weight ultraviolet light absorber (UVA) of the hydroxyphenyl benzotriazole class, imparting good light stability to a variety of polymers.
