>Chimassorb 2020 Features: Block oligomeric hindered amine light stabilizer, excellent compatibility, high extraction resistance.

>Highly effective light stabilizer for polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers.

>It imparts unique long-term thermal protection to PP filled articles and carbon black filled systems. HALS 2020 is highly effective as a long-term thermal stabilizer in thin and thick articles and shows high extraction resistance.

>It’s concentrations range between 0.1 % and 1.5 %, depending on the substrate, processing conditions and application.

Handing and Safety: 

>HALS 2020 requires no special safety measures, provided the usual precautions for handling chemicals are observed.

>For additional handing and toxicological information, please consult us for Maternal Safety Date Sheet.
