Product Performance Light Stabilizer 783 is a next-generation composite product of polymeric high-molecular-weight hindered amine light stabilizers, with excellent processing thermal stability, good compatibility and water-extraction resistance. Through mechanisms such as capturing free radicals, eliminating the harm of free radicals, decomposing hydroperoxides and quenching excited-state energy, it delivers low-concentration, high-efficiency protection against photo-thermal degradation. The action mechanisms of different hindered amine light stabilizers achieve optimal complementarity within this system; the activity of the functional groups is enhanced and the synergistic effect is brought into full play. This product is an excellent general-purpose light stabilizer for both thick and thin articles, offering a superior price-performance ratio.
Main Uses This product is an excellent general-purpose light stabilizer for polymers. It can be used for photo-thermal aging protection of polyethylene, polypropylene, polyurethane, polyoxymethylene, polyamide and polyester elastomers, and can also be applied in ABS and engineering plastics. When used in LDPE or LLDPE agricultural film systems, at reduced addition levels this product offers a superior price-performance ratio compared with the currently best hindered amine light stabilizers.
StorageThis product should be stored in a dark, dry place at a temperature below 30 °C.
Packaging25 kg fiber drum with inner plastic liner.
