Gli stabilizzatori di luce con ammina ostacolata (HALS) proteggono i polimeri dalla degradazione dovuta all'esposizione ai raggi UV neutralizzandoli. HALS si rigenera durante la neutralizzazione e continua a fornire protezione per tutta la vita del prodotto finale. Agiscono anche come antiossidanti primari con una bassa generazione di colore.
