In the highly competitive paper manufacturing sector, achieving optimal paper brightness is a critical factor in product quality and market appeal. Optical brighteners, often referred to as fluorescent whitening agents (FWAs), are indispensable for this purpose. This guide focuses on the application and benefits of Fluorescent Brightener 220, a key chemical auxiliary agent, for enhancing paper brightness. As a dedicated supplier, we aim to provide insights into sourcing and utilizing this vital component effectively.

The Science Behind Paper Brightness

Paper's natural tendency is to have a slight yellow hue due to lignin and other impurities. Optical brighteners counteract this by absorbing ultraviolet (UV) light and re-emitting it as visible blue light. This blue light neutralizes the yellow cast, making the paper appear significantly whiter and brighter to the human eye. The effectiveness of an FWA is measured by its fluorescence intensity and its affinity to paper fibers.

Fluorescent Brightener 220: A High-Performance Solution

Fluorescent Brightener 220 (CAS 16470-24-9) is a preferred choice for paper mills due to its excellent performance characteristics. As a leading manufacturer, we ensure our product meets the high demands of the paper industry:

  • Superior Whiteness: Delivers a clean, brilliant white shade with a neutral to slightly blue undertone, ideal for premium paper grades.
  • Excellent Water Solubility: Its high solubility simplifies incorporation into various papermaking processes, including pulp addition, surface sizing, and coating formulations.
  • Process Stability: It demonstrates good stability in the presence of common papermaking chemicals like sizing agents (e.g., starch, CMC, PVA) and is relatively tolerant to variations in water hardness.
  • Cost-Effectiveness: High whitening efficiency at low dosage rates makes it an economical choice for manufacturers looking to purchase quality chemicals at a competitive price.

When you choose to buy Fluorescent Brightener 220 from NINGBO INNO PHARMCHEM CO.,LTD., you are partnering with a reliable supplier committed to product excellence and consistent supply.

Key Application Stages in Papermaking

Fluorescent Brightener 220 can be effectively applied at several critical stages of the papermaking process:

  • Wet End Addition (Pulp Whitening): Incorporating the brightener directly into the pulp slurry ensures uniform distribution and maximum whiteness throughout the entire paper sheet.
  • Surface Sizing: Application during the surface sizing process enhances the paper's surface brightness and printability, making it ideal for high-quality graphic papers.
  • Coating Application: It is widely used in paper coating formulations to achieve the highest levels of brightness and gloss for coated paperboard and specialty papers.
