Chimassorb® 2020 by BASF is a high molecular weight hindered amine light stabilizer (HALS). Offers an optimal combination of exceptional levels of UV- and long-term thermal stability and ancillary properties such as minimal pigment interaction and improved melt flow control.<br>
<ul style="padding-left: 40px;"><li>It is a highly effective for polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers.</li>
<li>In certain instances, it is effective in polyacetals, polyamides, polyurethanes, flexible and rigid PVC as well as PVC blends and in certain styrenic elastomer.</li>
<li>Chimassorb® 2020 shows excellent polymer compatibility and high extraction resistance.</li>
<li>>Recommended dosage level is 0.05-1.4%. Chimassorb® 81 FL by BASF is a benzophenone grade that acts as a UV absorber. Suitable for low-density and linear low-density polyethylene and polyethylene-vinyl acetate copolymers for agricultural films.<br>
<ul style="padding-left: 40px;"><li>Imparts good light stability when used in combination with hindered amine light stabilizer (HALS) of Chimassorb®, Tinuvin® or Uvinul® range.</li>
<li>Protects other polymers against degradation caused by light exposure.</li>
<li>Shows good compatibility with polyolefins and plasticized PVC.</li>
<li>It can also be used in combination with antioxidants, phosphites and other light stabilizers.</li>
<li>It can be used as a UV barrier to protect the contents of packages for both industrial and consumer applications.</li>
<li>Suitable for thick films, typically >100 µm and thick sections.</li>
<li>Its low vapor pressure prevents losses during processing.</li>
<li>Low migration rates reduce the risk of blooming.</li>
<li>It can be used in high-density polyethylene molded articles like crates when used in the combination with HALS.</li>
