Technical Specifications

Key Features and Advantages

• Superior Fluorescent Performance: Delivers intense blue-white fluorescence that significantly improves the visual appeal of paper products.
• Excellent Compatibility: Works synergistically with common carriers such as CMC, PVA, and starch without causing precipitation or instability.
• Liquid Convenience: The low viscosity formulation allows for precise metering and continuous addition, reducing labor costs and downtime.
• Alkaline Stability: Maintains performance integrity within the typical pH range of papermaking processes, ensuring consistent results.
• Versatile Application: Suitable for multiple stages including pulping, surface sizing, and coating preparation.

Industrial Applications

This optical brightener is primarily utilized in the papermaking industry to enhance the optical properties of various paper grades. During the coating process, it can be introduced at any stage, showing optimal results when combined with standard binding agents. For surface sizing applications, the recommended dosage ranges from 0.5 to 20 grams per liter, depending on the desired whiteness level. When adding directly to the pulp, it is crucial to avoid direct contact with cationic chemicals to prevent interaction issues. The typical dosage based on the weight of absolutely dry pulp should remain between 0.1 percent and 1.5 percent. This flexibility makes it an ideal choice for manufacturers seeking a reliable drop-in replacement for existing whitening protocols.

Storage and Packaging

To maintain optimal chemical stability, Optical Brightening Agent 4PL-C should be stored in a cool, dry environment at room temperature. Avoid exposure to direct sunlight or extreme temperature fluctuations. We offer flexible packaging options to suit diverse logistical requirements, including 50kg and 230kg barrels, as well as 1000kg IBC tanks. Custom packaging solutions are available upon request to align with specific supply chain needs. As a global manufacturer, we ensure all shipments are accompanied by a Certificate of Analysis (COA) to verify compliance with stated specifications.
