UV absorber triazine-5

　　Chemical name: 2,4,6-tris (2'-keto 4'-n-butoxyphenyl)-1,3,5-triazine (a mixture of three components)

　　English name: 2,4,6-tri(2'-hydroxy-4'-n-butoxyphenyl)-1,3,5-triazine

　　Molecular formula: C33H39O6N3(I) C29H31O6N3(II) C26H23O6N3(Ⅲ)

　　Relative molecular mass: 573.69; 517.58; 405.37

　　Appearance: light yellow powder

　　Melting point: 165～166℃; 211～212℃

　　Solubility: soluble in hexamethylphosphoric triamide (HPT), slightly soluble in n-butanol, insoluble in water

　　Application performance: This product is an excellent ultraviolet absorber with excellent heat and light stability, suitable for a variety of polymers. Adding a small amount to PVC agricultural film can increase the service life of products by 1 to 3 times. In POM, this product can not only improve the weather resistance and heat resistance of the product, but also have outstanding impact toughness. In oxidized polyether, it helps to improve its storage and service life, and is also conducive to processing. But it must absorb part of the visible light and make the product yellowish.

　　Safety: This product is non-flammable, non-corrosive, non-polluting, and has good storage stability
