介绍 | BLS® 1944 is a high molecular weight hindered amine light stabilizer. It provides outstanding light stability to many polymers and it also provides long-term stability to polyolefins by a radical trapping mechanism similar to that of hindered phenols. Significant levels of stabilization are achieved at relatively low concentrations. Because of its polymeric structure, BLS® 1944 has a very low volatility (even at high temperatures), low extractability and low migration rate from polymeric substrates. When compounded, BLS® 1944 imparts no negative effects on a substrate's initial color, its low dust, free-flowing form makes it exceptionally convenient to handle. Applications: BLS® 1944 is a polymeric hindered amine light stabilizer offering excellent protection against ultraviolet degradation. BLS® 1944 areas of application include polyolefins (polypropylene, polyethylene), olefin copolymers such as EVA as well as blends of polypropylene with elastomers. In addition, BLS® 1944 can be highly effective in polyacetals polyamides, polyurethanes, flexible and rigid PVC, as well as PVC blends and in some styrenic elastomer and adhesive specialty applications.
