LS-2020

Block oligomeric hindered amine light stabilizer

Beschreibung

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.

Anwendungen

LS-2020 is a highly effective light stabilizer for polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers. In addition, in certain instances LS-2020 is highly effective in polyacetals, polyamides, polyurethanes, flexible and rigid PVC, as well as PVC blends and in certain styrenic elastomer and specialty adhesive applications.
