3、Application:
Fluorescent Brightener OB can be widely used in plastics such as PVC, PS, ABS, PE, and PP. Due to its superior whitening effect, excellent thermal stability, and low dosage requirement, it has become one of the most commonly used fluorescent brighteners domestically. It is also suitable for whitening polyester fibers, coatings, paints, inks, and acrylics. Fluorescent Brightener OB can be used together with dyes to produce special brightness, which is particularly effective in color formulations.
