Methylene bis[3-2(-benzotriazolyl)-2-hydroxy-5-tert-octylphenyl]

 UV-360 is a highly effective ultraviolet light absorber. It exhibits strong absorbance in the 300-400nm region and is compatible with various resins, Featured by its character of very low volatile, UV-360 can be used in combination with HALS or antioxidant, it is particularly suitable for processing and aging conditions where high temperature, low volatility and good compatibility are required, such as complex molding, fibers, sheets, laminated or coextruded semi-finished parts.
