Chimassorb 2020 is a high molecular weight block oligomeric hindered amine light stabilizer (HALS). It shows excellent polymer compatibility and high extraction resistance.

One of the unique features of Chimassorb 2020 is a very narrow molecular weight distribution, resulting in a consistent performance in use and processing.

This ingredient combines the typical benefits of a variety of high molecular weight HALS. It provides superior light/thermal stability to polymers and improved ancillary properties like improved polymer processing.

Applications

Chimassorb 2020 is a highly effective light stabilizer for polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers.

In addition, in certain instances Chimassorb 2020 is highly effective in polyacetals, polyamides, polyurethanes, flexible and rigid PVC, as well as PVC blends and in certain styrenic elastomer and specialty adhesive applications.

Features & Benefits

Chimassorb 2020 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. It provides excellent UV stability to PP fibers, PP tapes, PE films, thick articles of PP and PE. Furthermore, it imparts unique long-term thermal protection to PP filled articles and carbon black filled systems. Chimassorb 2020 is highly effective as a long-term thermal stabilizer in thin and thick articles and shows high extraction resistance.
