Achieving optimal paper brightness requires careful selection and application of specialized chemicals. Optical Brightening Agent 4PL-C, offered by NINGBO INNO PHARMCHEM CO.,LTD., is a highly effective liquid solution designed to enhance paper whiteness at critical production stages, particularly in pulping and surface sizing.

When incorporating OBAs into the pulp, proper handling is essential. It's crucial to avoid adding the agent concurrently with cationic chemicals to prevent precipitation and ensure maximum efficiency. The recommended dosage for pulp addition is typically between 0.1% to 1.5% based on the weight of absolutely dry pulp. This precise application of a fluorescent whitening agent for pulp ensures that the brightening effect is integrated from the very beginning of the paper-making process.

For surface sizing, Optical Brightening Agent 4PL-C, when combined with carriers such as CMC, PVA, and starch, yields superior results. The typical dosage ranges from 0.5 to 20g/L. This application method is key for achieving a bright and uniform surface finish, which is vital for high-quality printing and visual appeal. Understanding these optical brightening agent application methods allows paper manufacturers to fine-tune their processes for the best outcome. NINGBO INNO PHARMCHEM CO.,LTD. provides this essential liquid optical brightener 4PL-C to support these applications.

The choice of an appropriate paper sizing agent is often influenced by its compatibility with other additives, including OBAs. Our 4PL-C is formulated for excellent compatibility, ensuring smooth integration into your existing sizing formulations. Manufacturers looking to buy high-performance OBAs will find NINGBO INNO PHARMCHEM CO.,LTD. a reliable partner for enhancing paper quality and achieving market-leading brightness.
