Factory Wholesale Ultraviolet Light Absorber
Chemical Characteristics
Ultraviolet absorber is a kind of light stabilizer, can absorb sunlight and fluorescent light source in the ultraviolet part, but itself does not change.
Because the sun's rays contain a large amount of ultraviolet light harmful to colored objects, its wavelength is about 290-460 nanometers, these harmful ultraviolet light through the chemical Redox reaction, color molecules finally decompose and fade.
There are both physical and chemical ways to prevent color damage from harmful UV light.
Here is a brief introduction to the chemical method, that is, the use of UV absorbers to protect the object effective prevention, or to weaken its destruction of color.
Uv absorbers should have the following conditions
(1) can strongly absorb ultraviolet light (especially the wavelength of 290-400nm); (2) Good thermal stability, even in the processing will not change due to heat, heat volatility is small; Good chemical stability, no adverse reaction with the material components in the product; (4) Good miscibility, can be evenly dispersed in the material, no frost, no exudation; (5) The photochemical stability of the absorbent itself is good, does not decompose, does not change color; Colorless, non-toxic, odorless; resistance to immersion washing; Cheap and easy to get; 9. Insoluble or insoluble in water.
Uv absorbers can be classified into the following groups according to their chemical structure: salicylate esters, phenylketones, benzotriazoles, substituted acrylonitrile, triazines and blocked amines.
Product Introduction And Features
Ultraviolet absorbent is the most widely used one kind of light stabilizer, according to its structure can be divided into salicylate esters, benzophenone, benzotriazole, substituted acrylonitrile, triazines, etc., the industrial application of the most benzophenone and benzotriazole. The quencher is mainly a metal complex, such as divalent nickel complex, often and ultraviolet absorbent and, synergistic effect, ultraviolet absorbent is a kind of light stabilizer, can absorb sunlight and fluorescent light source in the ultraviolet part, and itself does not change.
Because the sun's rays contain a large amount of ultraviolet light harmful to colored objects, its wavelength is about 290-460 nanometers, these harmful ultraviolet light through the chemical Redox reaction, color molecules finally decompose and fade.
There are both physical and chemical ways to prevent color damage from harmful UV light.
Here is a brief introduction to the chemical method, that is, the use of UV absorbers to protect the object effective prevention, or to weaken its destruction of color
Use
It can effectively absorb ultraviolet light with a wavelength of 270-380 nm, mainly used for polyvinyl chloride, polystyrene, unsaturated resin, polycarbonate, polymethyl methacrylate, polyethylene, ABS resin, epoxy resin and cellulose resin, etc. It is suitable for photosensitive materials such as color film, color film, color paper and polymer, etc. Especially suitable for colorless transparent and light products; For strong absorption, high performance ultraviolet absorber
