Riasorb UV 944 | UV-944

A polymeric hindered amine light stabilizer (HALS) of N-H type that protects polymers from degradation due to ultraviolet radiation and long term heat aging

RIASORB UV-944 areas of application include polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers. In addition in certain instances.

RIASORB UV-944 is highly effective in polyacetals polyamides, polyurethanes, flexible and rigid PVC, as well as PVC blends and in certain styrenic elastomer and adhesive specialty applications. RIASORB UV-944 imparts excellent light stability to thin articles, particularly fibers and films. In thick cross sections, it is specifically suitable for polyethylene articles.

RIASORB UV-944 is highly effective as a long-term thermal stabilizer in thin and thick articles and shows good extraction resistance. Use with sulfur-containing additives such DSTP or DLDP can have a negative influence on the effectiveness of RIASORB UV-944.
