UV Absorber 326 Cas 3896-11-5 UV-326

UV absorber refers to a preparation that can prevent a large amount of ultraviolet rays from passing through. UV absorbers should have the following conditions: good thermal stability, no change due to heat even during processing, and low thermal volatility; It can strongly absorb ultraviolet radiation (especially at wavelengths of 290-400nm) and has good chemical stability, without adverse reactions with the material components in the product; Good miscibility, can be evenly dispersed in the material, does not spray frost, and does not leak out; The absorbent itself has good photochemical stability, does not decompose, and does not change color; Colorless, non-toxic, and odorless; Resistant to immersion and washing; Affordable and easily obtainable
