• Application of Light Stabilizer 770 CAS:52829-07-9

  Light stabilizer 770 is a low molecular weight hindered amine light stabilizer. Its efficacy is better than that of UV absorbers and nickel-containing stabilizers. Light stabilizer 770 has good thermal stability. Contrary to UV absorbers, it does not absorb visible spectrum. , so it is not affected by the thickness of the plastic and will not affect the color of the plastic. Particularly suitable for plastics requiring good light stability such as polypropylene, polyurethane, HDPE, polystyrene, high impact polystyrene, EPDM, ABS, SAN, ASA, polyamides and polyacetals (polyacetals), etc. Used together with UV absorber series, such as UV326, UV328, etc., it has better synergistic effect and better photostability. The general dosage is 0.2-1%. Light stabilizer 770 is a hindered amine light stabilizer with high efficiency and low toxicity. It has significant anti-photooxidative aging (sunscreen) effect. When used in combination with antioxidants, it can improve heat resistance, especially for polypropylene and high-density polyethylene. Its atmospheric aging resistance is far superior to that of general UV absorbers and quenchers (nickel-chromium compounds), especially for thick products. Unlike traditional UV absorbers, its efficacy has nothing to do with product thickness, so it is also suitable for high Products with specific surface area, such as: film, flat wire. Its advantage lies in its high efficiency, and at the same time it has good compatibility and dispersibility with resins. Light stabilizer 770 is mainly used in polypropylene, impact modified polypropylene (TPO), EPDM, polystyrene, impact polystyrene, ABS, SAN, ASA, and also used in polyurethane, polyamide, polyoxymethylene, etc. Because 770 has excellent light protection properties, it has been widely used in the field of polymers.
