In the competitive landscape of plastic manufacturing, achieving a pristine white finish is often paramount. This is where optical brighteners, also known as fluorescent whitening agents (FWAs), play a crucial role. These specialized chemical additives absorb ultraviolet light and re-emit it as visible blue light, effectively masking yellowing and creating a brighter, whiter appearance in materials. For businesses looking to buy high-quality plastic additives, understanding these agents and their applications is vital.

One highly effective compound in this category is Fluorescent Brightener 378 (CAS 40470-68-6). Renowned for its high purity of ≥99%, this FWA is a preferred choice for manufacturers working with polymers such as PVC and polystyrene. Its ability to deliver superior whitening with minimal usage makes it a cost-effective solution for improving product aesthetics. As a leading manufacturer and supplier based in China, we are dedicated to providing consistent quality and competitive pricing for this essential chemical.

The application of Fluorescent Brightener 378 extends across various plastic products. It is particularly effective in whitening PVC and polystyrene series products, as well as other thermoplastics. This means that whether you are producing films, profiles, molded parts, or synthetic leather, this brightener can significantly enhance the visual appeal of your end products. Its excellent heat resistance and compatibility with these polymers ensure seamless integration into existing manufacturing processes.
