[Product Name]：Fluorescent Brightener OB-1

Brief Introduction

Insoluble in water, soluble in high-boiling-point organic solvents such as Benzene Trichloride and Diphenyl ether. As this product is of high melting point and strong stability, it has fine thermo-stability. And Because of the character of hydrophobicity, it has fine sunlight-proof feature. The strong fluorescence can improve both the whiteness and brightness. It can be used in chemical fiber like disperse dye and used in plastics like oil soluble colorant.
