In the competitive paper industry, achieving superior whiteness and brightness is paramount for product differentiation and customer satisfaction. As a leading chemical auxiliary agent supplier, we understand the critical role optical brighteners play. Among the most effective is Fluorescent Brightener 220 (CAS 16470-24-9), a versatile solution for enhancing paper quality. This article will guide you through selecting and utilizing this key ingredient.

Understanding Optical Brighteners

Optical brighteners, also known as fluorescent whitening agents (FWAs), are compounds that absorb ultraviolet light and re-emit it as visible blue light. This blue light counteracts any yellow cast in the paper, making it appear brighter and whiter. For paper manufacturers, choosing the right FWA ensures optimal performance and desired aesthetic qualities.

Fluorescent Brightener 220: A Superior Choice for Paper

Fluorescent Brightener 220, often referred to as Optical Brightener APC or BBU, is highly regarded for its effectiveness in the paper industry. Its key attributes include:

  • Exceptional Whiteness: It imparts a distinct blue light tone, significantly increasing paper brightness.
  • Good Water Solubility: Easily soluble in water, it integrates seamlessly into various papermaking processes.
  • Process Stability: It remains stable in the presence of peroxide and hypochlorite bleaching agents, and is not significantly affected by hard water.
  • Application Versatility: Primarily used for surface sizing and the whitening of surface coatings, it can also be incorporated into the pulp itself.

When you buy Fluorescent Brightener 220 from a reputable supplier like NINGBO INNO PHARMCHEM CO.,LTD., you ensure access to a high-purity product that meets stringent industry standards. We offer competitive pricing for bulk orders, making it an economically sound choice for enhancing your paper products.

Key Applications in Papermaking

The primary applications for Fluorescent Brightener 220 in paper manufacturing include:

  • Pulp Whitening: Incorporating the brightener during the pulping process ensures uniform whitening throughout the paper sheet.
  • Surface Sizing: Applying it during surface sizing improves the overall brightness and print receptivity of the paper.
  • Coating Processes: It is highly effective in coating formulations, enhancing the visual appeal of coated papers used for high-quality printing and packaging.

Dosage and Usage Recommendations

The optimal dosage of Fluorescent Brightener 220 typically ranges from 0.05% to 1.2% based on the absolute dry pulp weight for pulp addition. In surface sizing and coating applications, dosages of 0.5-10 g/L or 0.1-1.4% (of coating weight) are common, often in conjunction with starch, CMC, or PVA. Consulting with our technical team can help determine the most efficient dosage for your specific paper grade and production requirements.
