Chimassorb 944 Usage And Synthesis

Characterization	Chimassorb 944 is a high molecular weight hindered amine light stabilizer (HALS). It shows excellent compatibility, good resistance to extraction and low volatility.
Applications	Chimassorb 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 Chimassorb 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.
Features/benefits	Chimassorb 944 imparts excellent light stability to thin articles, particularly fibers and films. In thick cross sections it is specifically suitable for polyethylene articles. Chimassorb 944 is highly effective as a long-term thermal stabilizer in thin and thick articles and shows good extraction resistance.
