For paper manufacturers, achieving optimal whiteness and brightness is paramount to product appeal and perceived quality. Optical brightening agents (OBAs) play a crucial role in this process, and Optical Brightening Agent BBU-480, with its CAS number 16470-24-9, stands out as a highly effective solution. As a reputable Optical Brightening Agent BBU-480 manufacturer in China, we understand the unique demands of the paper industry and offer a product designed for superior performance.

Optical Brightening Agent BBU-480, identified by C.I. No. 220, is a mixture substance characterized by its yellowish granule appearance. Its anionic nature makes it compatible with various papermaking processes, particularly in pulp and surface sizing applications. The key to its efficacy lies in its ability to absorb ultraviolet light and re-emit visible blue light, thereby counteracting the natural yellow tinge of paper pulp and substrates. This fluorescent action significantly enhances the perceived whiteness, making the paper appear brighter and more visually appealing to end-users.

When considering how to buy optical brightener 220 for paper, it's essential to understand its application methods. BBU-480 can be directly added into the pulp. For optimal results, it is recommended to avoid direct contact or mixing with cationic chemicals, which can reduce its effectiveness. The typical dosage for pulp addition ranges from 0.01% to 0.4% based on the weight of absolutely dry pulp. In surface sizing applications, BBU-480 demonstrates excellent performance, especially when used with carriers such as CMC (Carboxymethylcellulose), PVA (Polyvinyl Alcohol), and starch. The usual dosage for surface sizing is between 0.1 to 3 grams per liter. These application guidelines ensure that paper manufacturers can effectively integrate this fluorescent whitening agent into their existing workflows to achieve desired brightness levels.

The benefits of using Optical Brightening Agent BBU-480 in paper manufacturing are numerous. It not only improves the aesthetic quality of the paper but also ensures consistency in brightness, which is critical for printing grades, packaging materials, and specialty papers.
