The papermaking industry demands high whiteness, brightness, and uniformity. As key additives, fluorescent brighteners enhance visual whiteness by absorbing UV light and emitting blue light, boosting paper quality and competitiveness. HairunChem offers three high-efficiency brighteners—2BL, 4PL, and HST—suitable for pulp addition, surface sizing, and coating, providing eco-friendly solutions for various paper types including cultural, packaging, and specialty papers.
