Fluorescent Brightener OB-1 is a complex organic compound that stimulates incident light to produce fluorescence, creating a whitening effect similar to fluorite. This optical brightening agent makes treated materials appear exceptionally white to the naked eye.

• High whitening strength with strong fluorescence intensity
• Broad application compatibility across multiple industries
• Excellent high temperature performance up to 359°C melting point
• Chemical structure: Distyryl double benzoxazole (C28H18N2O2)

Fluorescent Brightener OB-1 is widely used in textiles, papermaking, plastics, coatings, detergents, printing ink, wax, and packaging materials. Note that this product provides optical brightening and color supplementation only, and cannot replace chemical bleaching processes.

Typical usage per 100kg of polymer:

• Transparent applications: 0.0025-0.005% (2.5g-5g)
• General applications: 0.0025-0.025% (2.5g-25g)
• Maximum dosage: Not to exceed 0.03% (30g)

Available in 15kg bottles, or 5kg×4 cartons, or 5kg×2 cartons. Store in cool, dry conditions away from heat sources and direct sunlight. Maintain good ventilation in storage and mixing areas. Transport according to general chemical handling regulations.
