Ultraviolet Absorbent-360

Ultraviolet Absorbent-360 for variety of polymers resin CAS NO 103597-45-1

Ingredients: 2,2'-methylene bis(6-(2H-benzotriazole-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol)
Introduction:
This product is high-efficiency ultraviolet absorbent and widely soluble in many resins. This product is used in polypropylene resin, polycarbonate, polyamide Resin and others.
Application:

UV-360 is a very low volatile, used in a variety of polymers and resin composition. UV-360 is an excellent UV absorber and can be used in polyacrylic resin, polyalkene, polyamide and in elastoplastic goods with good compatibility and higher UV absorbability. Used with other additive such as antioxidanr, it shows synergistic effect. Yellowish powder, insolunle in water, soluble in esters. And benzoid solvents, high thermostability.
