Application field 
UV Absorber Methylene bis-benzotriazolyl tetramethylbutylphenol is a highly efficient ultraviolet absorber, the appearance is light yellow crystalline powder, can absorb 300-400nm ultraviolet, and has the ability to absorb UVA and UVB. It has the dual function of absorption and scattering to UVA band ultraviolet light, and has the extremely high light stability. When it is used in combination with other UVB wave ultraviolet absorbers, it has a significant synergistic effect and can obviously improve the SPF value of the formula.
As an ultraviolet absorber, UV Absorber Methylene bis-benzotriazolyl tetramethylbutylphenol has very low volatility and good compatibility with many polymers, suitable for acrylate, polyester, polycarbonate, polyamide, polyolefin, styrene polymers, elastomers, adhesives, etc. especially suitable for high concentration, low volatility and good compatibility, processing and aging conditions.
UV Absorber Methylene bis-benzotriazolyl tetramethylbutylphenol can be extruded by powder, solution or melt to prevent crystallization seepage and sublimation, and can also be used for casting, thin layer construction of fiber, paper and wallpaper.
UV Absorber Methylene bis-benzotriazolyl tetramethylbutylphenol is a general chemical, with good storage and transportation stability, it is non-flammable and non-explosive, non-toxic and harmless.
