Technical Specifications

Performance Features

Our BA-550 formulation is engineered to offer distinct advantages in continuous production environments. The granular form ensures convenient handling and precise dosing, reducing waste and operational complexity. Users benefit from excellent fluorescent whitening performance during pulp treatment, surface sizing, and coating processes. The anionic nature of the compound prevents undesirable interactions with common anionic additives, ensuring process stability. Furthermore, the high E-value indicates strong whitening efficiency, allowing for lower dosage rates while achieving optimal brightness levels. This efficiency translates directly into cost savings and enhanced end-product quality. The substance demonstrates remarkable resistance to hard water and maintains its efficacy across a broad pH range, providing flexibility in diverse manufacturing setups.

Industrial Applications

In the paper industry, this agent is directly incorporated into the paper pulp. Operators must avoid mixing it with cationic chemicals to prevent precipitation or loss of efficacy. The recommended proportion ranges from 0.03 percent to 1.0 percent based on the weight of absolute dry paper pulp. For textile applications, specifically cotton dyeing, the dosage is typically between 0.05 percent and 0.4 percent on weight of fabric. Processing conditions involve a liquor ratio of 1:10 to 1:30, with temperatures maintained between 80 degrees Celsius and 100 degrees Celsius for durations of 30 to 60 minutes. These parameters ensure deep penetration and uniform whitening effects. Additionally, it serves as a valuable additive in surface sizing solutions, improving the visual appeal of coated paper grades used in high-end printing and packaging.

Quality Assurance and Storage

To maintain integrity and performance, Optical Brightening Agent BA-550 is packaged in secure 25kg bags. Custom packaging solutions are available to meet specific logistical requirements. The product exhibits stability for over two years when stored correctly. We recommend storage at room temperature in a dry, well-ventilated area away from direct sunlight and moisture.
