| Applications | Optical brightener OB is a fluorescent dye, or white dye, which is a complex organic compound. Mainly used for plastic masterbatch, plastic filler masterbatch, ink. In the field of plastics, thermoplastic plastics, thermosetting plastics, five kinds of general plastics and various engineering plastics have a good whitening performance, late weatherability stability. In the field of coatings and inks, it mainly improves the whiteness, brightness and brightness, enhances the grade of products, improves the wetting effect of products, pigments and paints, and has long-lasting fluorescence intensity, making the products long-lasting. The fluorescent whitening agent OB can be widely used in PVC, PS, ABS, PE, PP and other plastics. Superior fluorescent whitening effect, good thermal stability and low additive amount. It is also suitable for whitening polyester fiber, coatings, paints,candle, inks and acrylic acid. The fluorescent whitening agent OB can be Shared with dyes to produce a special brightness, which is particularly effective in colour formulations. |
| Product dosage | 1. Dosage description As a high-range auxiliary, the amount of optical brightener OB is very small. The amount of optical brightener OB is normally added per 100kg of polymer PVC: white 1-5 parts per million (10g -- 50g); Transparent material 0.01-0.1 (0.1g-1g)(can improve the brightness of PVC); PS: 0.1 PPM (1g) white, 0.01 -- 0.1 PPM (0.1g-1g) transparent; ABS: natural color: 1/10000 -- 5(10g-50g)(can effectively eliminate inherent yellow in ABS) white: 1/10000 -- 5(10g-50g); PE, PP: colorless 0.05-0.1 (0.5g-1g) white 0.5-5 (5G-50g); Other plastics: dosage can refer to each case above, such a small amount of addition is a big effect.nt yellow in ABS) White 0.01 -- 0.05% (10g-50g) Other plastics: dosage can refer to the above examples |
