Products Description of UV Absorber 326CAS#3896-11-5

Ultraviolet absorbers refer to a kind of preparation that can prevent a large amount of ultraviolet rays from passing through. Ultraviolet absorbers should have the following conditions: good thermal stability, which will not change due to heat even during processing, and low thermal volatility; can strongly absorb ultraviolet rays (especially wavelengths of 290-400nm); good chemical stability, and will not react adversely with the material components in the product; good miscibility, can be evenly dispersed in the material, no frost, no seepage; the absorber itself has good photochemical stability, does not decompose, does not change color; colorless, non-toxic, odorless; resistant to immersion; cheap and easy to obtain. Ultraviolet absorbers can be divided into the following categories according to their chemical structure: salicylates, benzophenones, benzotriazoles, substituted acrylonitriles, triazines and other categories. Fabrics with ultraviolet absorbers added can obtain good ultraviolet blocking effects. It can reduce fading and enhance the light fastness of polyester disperse dyes. Ultraviolet absorber UV-326 is one of them.
