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, freeflowing form makes it exceptionally convenient to handle.
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. |
