  Description: CAS NO: 1533-45-5 Appearance: bright yellow crystals powder Purity: 98.5%Min Melting point: 355-360°C Solubility: insoluble in water,but soluble in high boiling point organic solvent such as phenyl-chloride Packaging: Packaged in cardboard drums,20kg or 25kg each Properties: Does not dissolve in water, can dissolve in such high boiling point solvents as trichlorobenzene, diphenyl ether,etc.; Because this product has high melting point and strong stability,so it has very good heat resistance; Because this product's hydrophobic nature, so it has good light fastness; and for it has strong fluorescence, it can not only improve the whiteness of the products but also can improve the brightness, so it can be used as disperse dyes in the chemical fibre, can be used like oil dissolving coloring agent in the plastics. Applications: 1.Suitable for whitening chemical fibers, such as the polyester fibre, nylon fiber, polypropylene fiber and so on. 2. Suitable for whitening and brightening polypropylene plastic, hard PVC, ABS . EVA, polystyrene, polycarbonate, etc. 3. Suitable to be added into the conventional polymerization of polyester and nylon. 4. Especially suitable for whitening the plastics of elevated temperature compaction.
