Light Stabilizers 622 and 770 — Strong Long-Term Thermal Stability

Light stabilizer 622 is a polymeric high-molecular-weight hindered-amine light stabilizer (HALS); it is an oligomer with excellent processing thermal stability and good compatibility with various resins. Being a high-molecular-weight compound, it also has good water-extraction resistance, so during processing or use its water-extraction resistance is good and it is not easily lost. This product can effectively prevent the degradation of polymers by light, heat, climate and moisture.
It is far superior to general low-molecular-weight HALS. Polymeric HALS offer better heat resistance, extraction resistance, and lower volatility and migration. As a light stabilizer, this product is suitable for polyethylene, polypropylene, polystyrene, olefin copolymers, polyester, flexible PVC, polyurethane, polyoxymethylene and polyamide, etc.
Storage and packaging: inner plastic bag in carton, net weight 25 kg/carton
Light stabilizer 622 is non-toxic, non-flammable, non-explosive, non-corrosive and has good storage stability, and can be used in plastics in contact with food.
