　　Product usage and precautions

　　This product is a hindered light stabilizer, which itself has almost no ability to absorb ultraviolet rays, but it can effectively capture the active radicals produced by polymer materials under the action of ultraviolet rays, thereby exerting light stabilizing effect. This product is suitable for various plastics such as polypropylene, polyethylene, polystyrene, polyurethane, polyamide and polyester, especially in polyolefins. The light resistance of this product is several times that of general ultraviolet absorbers. No coloring, no pollution, good heat resistance and workability. It is used in combination with antioxidants and ultraviolet absorbers and has excellent synergistic effect.
