Optical Brightener VBL, identified by CAS number 12224-16-7, belongs to the stilbene triazine derivative class and is known for its anionic nature and cyan-purple fluorescent hue. Its primary function is to absorb ultraviolet light and re-emit it as visible blue light, effectively masking yellowing and making paper appear whiter and more brilliant. This makes it an essential component in pulp whitening, surface sizing, and coating formulations. If you are looking to buy optical brightener VBL, partnering with a reputable optical brightener VBL supplier China can ensure you receive a product of consistent quality and competitive price.

The application of Optical Brightener VBL in the paper industry is straightforward. It can be added directly into the pulp stage before alum or cationic auxiliary agents are introduced. The recommended dosage typically ranges from 0.05% to 0.4% of the absolute dry pulp weight. For surface sizing and coating applications, it can be dissolved in water and incorporated into the process, working effectively with agents like CMC, PVA, starch, or weak cationic sizing agents. Understanding these application methods is crucial for maximizing the benefits and ensuring optimal whiteness. For those seeking to purchase Optical Brightener VBL, considering its compatibility with other paper chemicals is also important.
