Applications

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 DLTP can have a negative influence on the effectiveness of RIASORB^® UV-944.
