Especially suitable for whitening plastics, such as the polyolefin, polyamide, polyacrylonitrile and so on. 　　2. Widely used in the film, injection molding and extrusion molding material, is suitable for all plastic processing. 　　Method of Application: Recommend consumption: Put about 20g OB brightener into every 100kg materiel, concrete consumption is adjusted according to compounding formula. 　　Packing: Packaged in cardboard drums, 20kg or 25kg each.

　　Appearance: bright yellow crystals powder 　　Assay: 98.5%Min 　　Melting point: 355-360ºC 　　Solubility: insoluble in water, but soluble in high boiling point organic solvent such as phenyl-chloride 　　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 fiber, can be used like oil dissolving coloring agent in the plastics. 　　Uses: 1. Suitable for whitening chemical fibers, such as the polyester fiber, 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. 　　Packing: Packaged in cardboard drums, 20kg or 25kg each.

　　CAS No: 27344-41-8 　　Appearance: light yellow or milk white crystals powder 　　Solubility: soluble in water, alcohol, ether DMF, etc. 　　Fluorescent tone: slight greenish blue 　　Properties: 　　Fluorescence Brightener CBS-X is bis-cinnamene monobiphenyl type optical fluorescence brightener. It is the best fluorescence brightener for detergent use. Can dissolve in water, have good whitening effect to the fiber, polyamide, albumen fiber under the room temperature. The whitening effect of its high density products is 2.7 times higher than the fluorescence brightener of diphenyl ethylene nistriazine type. It also has good bluish tint and dissolve dispersibility. The stability to sodium hypochlorite is extremely high, it is belongs to fluorescence brightener of bleaching resistance type. 　　Uses: Used in synthetic detergent, fancy soap and soap trades. 　　Method of Application: Can add it during any manufacturing processes when synthesizing detergent, fancy soap and soap, If mix it with fluorescence brightener 31#, the effect will be better. 　　Packing: Packaged in cardboard drums, 25kg each.
