For any product relying on a bright, clean white appearance, the choice of optical brightener is critical. Fluorescent Brightener 378 (CAS 40470-68-6) stands out in the market due to its unique combination of properties that make it an indispensable additive for numerous polymer applications. As a dedicated manufacturer and supplier, we understand the technical demands of our clients and are proud to offer a product that consistently meets and exceeds expectations.

The cornerstone of Fluorescent Brightener 378's effectiveness lies in its exceptional purity, typically assaying ≥99%. This high level of purity ensures consistent performance and predictable results when incorporated into plastic formulations. For purchasing managers and formulation scientists, this means less variability and greater confidence in the final product's visual quality. When you buy this brightener, you're investing in reliability.

Beyond purity, its performance characteristics are equally impressive. Fluorescent Brightener 378 exhibits excellent heat resistance, a vital attribute for plastics that undergo high-temperature processing. This property prevents degradation during extrusion or molding, ensuring that the whitening effect is maintained without discoloration or loss of efficacy. Additionally, it possesses good light fastness, contributing to the longevity of the brightened appearance in the end product.

The compatibility of this optical brightener with a wide range of substrates is another significant advantage. It is particularly effective in PVC and polystyrene products, offering a brilliant white shade that masks inherent yellowness. Its utility extends to other thermoplastics, making it a versatile solution for manufacturers looking to buy a single, high-performance additive for multiple product lines. As a direct supplier from China, we ensure that this versatility translates into cost-effectiveness for your operations.
