In the competitive world of polymer manufacturing, achieving superior aesthetic appeal is paramount. For many plastic products, this means not just color accuracy but also exceptional whiteness and brightness. This is where advanced additives like Fluorescent Brightener 367 (CAS 5089-22-5) come into play. As a premium optical brightening agent, it's designed to absorb ultraviolet light and re-emit it in the blue region of the visible spectrum, effectively masking yellowing and making materials appear whiter and brighter.

For product development managers and procurement specialists, understanding the capabilities and sourcing of such critical additives is key. Fluorescent Brightener 367, also known by synonyms like Hostalux KCB or FB 367, is a benzoxazole-type compound that offers remarkable performance. It typically appears as a yellow crystalline powder with a high purity, often exceeding 99%. Its formulation is optimized for insolubility in water but excellent solubility in common organic solvents, making it highly compatible with various polymer matrices during processing.

The primary application of Fluorescent Brightener 367 is in enhancing the whiteness of plastics, including plastic films, injection-molded materials, and EVA foamed plastics. Its effectiveness in these applications stems from its ability to integrate seamlessly into the polymer structure, providing a lasting brightening effect. For instance, manufacturers of plastic films seeking enhanced visual clarity for packaging or display purposes will find this brightener invaluable. Similarly, injection molding operations can leverage this additive to produce parts with a pristine white finish, crucial for consumer electronics housings or household goods.

When considering purchasing Fluorescent Brightener 367, looking for a reliable manufacturer and supplier in China is a strategic move. These suppliers often provide competitive pricing and ensure a stable supply chain. For example, sourcing CAS 5089-22-5 directly from a reputable China manufacturer means gaining access to high-quality materials with consistent batch-to-batch performance. This is essential for maintaining product quality and meeting production deadlines. If you are looking to buy Fluorescent Brightener 367 in bulk, inquire about wholesale pricing and lead times.

The dosage of Fluorescent Brightener 367 is typically very low, often ranging from 0.01% to 0.05% by weight, depending on the specific polymer and desired effect. This efficiency further contributes to its cost-effectiveness as a plastic additive. When evaluating suppliers, it's important to request detailed technical data sheets (TDS) and material safety data sheets (MSDS) to ensure proper handling and optimal application. Understanding the application methods and ensuring the brightener's compatibility with your specific polymer processing conditions, such as extrusion or molding temperatures, is also vital.

For businesses aiming to elevate the aesthetic appeal of their plastic products, Fluorescent Brightener 367 presents a compelling solution. By partnering with experienced China suppliers, you can secure a high-performance optical brightener that delivers exceptional results, enhances brand perception, and ultimately contributes to your product's market success. If you're seeking to buy this essential additive, initiating an inquiry with a trusted manufacturer is the first step towards achieving brighter, whiter plastics.
