Product Description:
Ultraviolet absorber THUV-328 is a highly efficient ultraviolet absorber, which can effectively absorb ultraviolet light with a wavelength of 270-340 nanometers, and its advantages are stable performance, low toxicity, and strong ultraviolet absorption ability, which can be used in plastic packaging materials and children's plastics in contact with food. It has good compatibility with a variety of polymers, and has antioxidant properties, and can be used with general antioxidants. It is a highly efficient UV absorption Chemicalbook agent with a maximum UV absorption peak of 345nm. The light stabilization efficiency is similar to that of UV-326 and UV-327. However, it has good compatibility with resin, low thermal volatilization, and high washing resistance. Mainly used in polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyester, epoxy resin, ABS resin and cellulose resin, the general dosage of about 1%. It also has excellent light stabilization effect in various coatings.
