The Applications of Optical Brightener OB-1
1. Optical Brightener OB-1 additives are often used to enhance the appearance of color of plastic and fabric, causing a "whitening" effect, making materials look less yellow by increasing the overall amount of blue light reflected.
2. Optical Brightener OB-1 is highly effective in polymer substrates such as engineering plastics, PE, PC, PVC, PS, ABS and PP, adhesive and other organic substrates. Especially rigid plastic (Polyethylene pipe, polypropylene pipe, Thermoplastics pipes, Thermosetting plastic pipe, etc) resulting in their strongly fluorescent appearance under UV illumination.
3. Optical Brightener OB-1 used in papers and fiber, paper brightness is typically measured at 457 nm, well within the fluorescent activity range of brighteners.
