Optical Brightening Agent BBU-480

Product Overview

Optical Brightening Agent BBU-480 is a high-efficiency anionic fluorescent whitening agent specifically engineered for the papermaking industry. Identified under C.I. No. 220, this specialized chemical compound delivers exceptional whiteness and brightness enhancement across various cellulose-based substrates. Its molecular structure, characterized by a sulfonated stilbene derivative framework, ensures superior solubility and compatibility within aqueous systems. Manufacturers seeking to elevate the visual quality of paper products will find this agent to be a critical component in modern formulation strategies.

Technical Specifications

Performance Features

This product distinguishes itself through robust performance metrics tailored for industrial continuous addition processes. The anionic nature of BBU-480 prevents adverse interactions with common cationic retention aids when managed correctly, ensuring consistent results. Key advantages include high fluorescence quantum yield, which maximizes whiteness perception under standard lighting conditions. Furthermore, the granular form facilitates easy handling and precise dosing, reducing waste and operational downtime. The agent exhibits remarkable stability over extended storage periods, maintaining efficacy for more than two years when kept under recommended conditions.

Industrial Applications

Optical Brightening Agent BBU-480 is versatile across multiple stages of paper production. In coating processes, it integrates seamlessly with carriers such as Carboxymethyl Cellulose (CMC), Polyvinyl Alcohol (PVA), and starch. The recommended dosage ranges from 0.05 to 0.4 percent based on dry pigment weight, allowing formulators to adjust brightness levels without compromising coating integrity. For surface sizing applications, the agent performs optimally at concentrations between 0.1 and 3 grams per liter. When added directly to pulp, it is crucial to avoid direct contact with cationic chemicals to prevent precipitation. The typical dosage for pulp addition is 0.01 to 0.4 percent relative to the weight of absolutely dry pulp. This flexibility makes it a valuable drop-in replacement for older whitening technologies.

Packaging and Storage

To ensure product integrity during transit and storage, BBU-480 is packaged in standard 25kg bags, with options for custom packaging solutions based on specific client logistics requirements. The material should be stored in a cool, dry environment at room temperature, away from direct sunlight and moisture sources. Proper storage guarantees the stated shelf life of over two years. Our global manufacturing facilities adhere to strict quality control protocols, ensuring every batch meets specified technical indices. Certificates of Analysis (COA) are available upon request to support regulatory compliance and quality assurance initiatives.
