Product Description
Product Details
Introduction
UV-770 is a hindered amine series light stabilizer. It is used in plastic molding. It appears as a white or slightly yellow powder or fine granules, with a melting point range of 80–86°C, a vapor pressure (20°C) of 1.3×10⁻⁸ Pa, a density (20°C) of 1.05 g/cm³, and a bulk density (crystalline fine granules) of 0.47–0.51 g/cm³.
A small amount of it added to plastic products has a good light stabilizing effect. If UV-770 is used in conjunction with other ultraviolet absorbers in polymers, it can play a greater role in anti-ultraviolet function.

Applications
This product is suitable for polypropylene, polyethylene, polystyrene, ABS resin, polyester, polyurethane, etc. In the polyurethane sector, it can be used in RIM, TPU, sealants, and other applications. The recommended usage range is 0.1% to 0.5%. When used in combination with antioxidants, it enhances heat resistance; when used with UV absorbers, it exhibits a synergistic effect, further improving light stability.
