1. Component: 2,2 '- methylene bis (6 - (2h-benzotriazole-2-yl) - 4 - (1,1,3,3-tetramethylbutyl) phenol)
2. Product Description: UV-360 is a high-efficiency ultraviolet absorber, which can absorb 300-400nm ultraviolet light and is widely compatible with a variety of resins. This product also has very low volatility and can be used with other light stabilizers or antioxidants. It is especially suitable for high-temperature environment of processing and aging. It can be formed by powder, solution or melting extrusion to prevent crystal exudation and sublimation. It is suitable for fiber, paper and wallpaper for casting and thin-layer construction. UV-360 is mainly used for polypropylene resin, polyimide, polycarbonate, modified polyphenylene ether, polyamide, polyacetal, polyolefin, polystyrene and elastomer, etc.
