Properties of UV Absorber UV-P (CAS 2440-22-4)
UV Absorber UV-P is soluble in gasoline, benzene, acetone and other organic solvents. It has very little solubility in water and is not decomposed by concentrated alkali or concentrated acid. It can ionize synthetic salts with heavy metals.
It is odorless and has good thermo stability under high temperature. Non-flammable, non-explosive, non-toxic, harmless to health.
Applications of UV Absorber UV-P (CAS 2440-22-4)
UV-P is a high-efficiency UV absorber, which can effectively absorb ultraviolet light with a wavelength of 270-380 nm. It almost does not absorb visible light. Stability in transparent articles is better than in colored articles. Particularly applicable to colorless and light-colored products.
It is mainly used for polyvinyl chloride, polystyrene, polyester, polycarbonate, polymethyl methacrylate, polyethylene, ABS, Resin, epoxy resin, cellulose resin, PP, PE, etc.
