In the competitive paper industry, achieving optimal brightness and whiteness is crucial for product appeal and market differentiation. Optical Brightener VBL, also known as Fluorescent Whitening Agent 85, manufactured by NINGBO INNO PHARMCHEM CO.,LTD., offers a powerful solution to this challenge. This bis-triazine amino type fluorescent brightener is specifically formulated to impart a brilliant white appearance to paper and pulp, making it an indispensable additive in modern papermaking processes.


The mechanism behind Optical Brightener VBL CAS 12224-06-5 for paper involves converting invisible ultraviolet light into visible blue-violet fluorescence. This optical trick effectively neutralizes the natural yellowish tint often found in paper, resulting in a cleaner, brighter, and more vibrant white. This not only enhances the aesthetic quality of the paper but also improves the readability and print contrast for various applications.


For paper manufacturers seeking to enhance their product line, incorporating a high purity optical brightener for pulp and paint is a strategic investment. Optical Brightener VBL from NINGBO INNO PHARMCHEM CO.,LTD. boasts a purity of over 99%, ensuring consistent and reliable performance. Its solubility in soft water facilitates easy integration into the pulp and paint formulations, allowing for precise dosage and uniform distribution. The stability of FWA 85 across a pH range of 6-11 and its resistance to hard water up to 300ppm are critical properties that contribute to its efficacy in diverse manufacturing environments.


Beyond its primary role in whitening, this optical brightener also contributes to the overall quality of the paper. It improves the average lightfastness of the treated material, ensuring that the enhanced whiteness persists over time. NINGBO INNO PHARMCHEM CO.,LTD. supplies this product in a light yellow powder form, making it convenient for handling and storage in industrial settings. Manufacturers looking to purchase Optical Brightener VBL can rely on the consistent quality and support provided by a reputable Fluorescent Whitening Agent 85 supplier.
