In the highly competitive paper industry, the pursuit of superior whiteness is relentless. Ningbo Inno Pharmchem Co.,Ltd. presents Sylic® Fluorescent Whitening Agent OBA BBU 220 as an indispensable solution for paper mills aiming to achieve unparalleled brightness and visual appeal. This advanced paper whitening agent is designed to transform ordinary paper products into brilliant, high-value offerings.


OBA BBU 220, a tetrasulfonic acid type Styrylbenzene derivative, operates on the principle of fluorescence. It absorbs the invisible ultraviolet light present in ambient light and re-emits it as a vibrant blue light. This optical phenomenon effectively masks any inherent yellowing in paper pulp or coatings, resulting in a significantly brighter and whiter appearance. For paper mills looking to enhance their product's aesthetic quality, choosing the right Fluorescent Whitening Agent BBU 220 for paper applications is paramount.


The versatility of OBA BBU 220 extends across various stages of paper manufacturing. It can be effectively used in dry paper pulp, with recommended dosages ranging from 0.1-0.3%. For coating applications, a dosage of 0.1-0.5% yields excellent results, while surface sizing can benefit from 0.1-2%. Its excellent solubility in warm water simplifies preparation and integration into existing production lines. This flexibility makes it an ideal paper brightener for diverse paper grades, from fine printing paper to specialized coated products.


Beyond its brightening capabilities, OBA BBU 220 offers notable stability and compatibility. It is acid & alkali resistant, ensuring consistent performance even in varying pH environments commonly encountered in paper processing. The agent demonstrates good compatibility with a range of common papermaking chemicals, including CMC, PVA, starch, and both anionic and cationic synthetic sizing agents, making it a highly adaptable paper additive. However, it is crucial to use it before alum or cationic auxiliaries during pulp whitening to prevent sedimentation.


Ningbo Inno Pharmchem Co.,Ltd. is committed to supplying high-quality paper whitening solutions like OBA BBU 220. This product is a crucial component for manufacturers aiming for superior paper whiteness. Its ability to deliver superior whiteness at low dosage makes it an economically viable choice, contributing to significant cost savings while maintaining premium quality. By partnering with a reliable OBA BBU 220 supplier, paper mills can ensure a consistent supply of this high-performance agent, securing their competitive edge in the market.
