BLS 1944 (70624-18-9 -US or 71878-19-8 – EU)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.
