In the competitive world of material manufacturing, achieving superior visual appeal is paramount. For products ranging from plastics to high-grade paper, the right chemical additives can make a significant difference in brightness and whiteness. Fluorescent Brightener 135, also known by its CAS number 12224-12-3, stands out as a highly effective optical brightener, widely sought after by formulators and manufacturers globally. As a leading supplier from China, understanding the benefits and applications of this compound is key for procurement managers and R&D scientists looking to buy quality materials. Fluorescent Brightener 135, with the molecular formula C18H14N2O2 and a molecular weight of 290.32, presents as a yellow powder. Its key characteristic is its ability to absorb ultraviolet light and re-emit it in the blue region of the visible spectrum, thus masking yellowing and enhancing perceived whiteness. This makes it an indispensable ingredient for products that require a brilliant, clean appearance. Key Applications for Manufacturers This versatile chemical finds extensive use across several industries: * Plastics: It is extensively employed in polyvinyl chloride (PVC), polystyrene, polyacrylate, high-density polyethylene (HDPE), and low-density polyethylene (LDPE). By incorporating Fluorescent Brightener 135, manufacturers can achieve a whiter, brighter plastic product, crucial for consumer goods and packaging. * Films and Sheets: For polyester films and acrylic sheets, this brightener enhances clarity and whiteness, improving the overall aesthetic quality. * Paper Industry: In the production of high-grade paper and business cards, it contributes to a superior brightness and a more professional finish. * Other Materials: Its applications extend to ABS, plexiglass, and even certain textile fibers where enhanced whiteness is desired.
