Advantage and Application:

1. UV-944 944 is a high molecular weight hindered amine light stabilizer (HALS). It shows excellent compatibility, high resistance to extraction and low volatility.

Areas of application include polyolefin (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 styrene elastomer and adhesive specialty applications.

Package:25KG cartons or drums
