For R&D scientists and product formulators, achieving the desired aesthetic qualities in plastic products is a continuous challenge. Optical brighteners are key tools in this endeavor, and Fluorescent Brightener 378 (CAS 40470-68-6) offers a powerful solution for enhancing whiteness and brightness. As a leading supplier, we aim to provide insights into its optimal use within various polymer systems.

Fluorescent Brightener 378 is particularly effective when incorporated into PVC and polystyrene. Its high purity (≥99%) ensures excellent compatibility and minimal interference with other additives, making formulation a more straightforward process. When deciding to buy this compound, consider the typical recommended concentrations often range from 0.05% to 0.5% by weight, depending on the base polymer and the desired level of whiteness. Exact formulation requires testing, but this provides a starting point for your R&D efforts.

The heat resistance of Fluorescent Brightener 378 is a significant advantage during processing. It can withstand temperatures commonly encountered in extrusion and injection molding without significant degradation. This is crucial for maintaining the integrity of the whitening effect and preventing yellowing that can occur with less heat-stable brighteners. When seeking to buy this product, inquire about its thermal stability data to ensure it aligns with your specific processing parameters.

For formulators working with other thermoplastics, this optical brightener also demonstrates good performance. Its ability to absorb UV light and emit blue fluorescence effectively counteracts any inherent yellow cast in the polymer, leading to a cleaner, brighter white. As a manufacturer committed to supporting innovation, we encourage formulators to explore its potential in custom blends and applications. We offer technical guidance to help you buy and integrate this product effectively.

Optimizing plastic formulations is about balancing performance, cost, and aesthetics. Fluorescent Brightener 378, available from a reliable supplier like us, offers a compelling combination of these factors. By understanding its properties and application guidelines, R&D professionals can confidently leverage this optical brightener to create visually superior plastic products.
