Masterbatches are essential components in the plastics industry, allowing for efficient coloring, additive incorporation, and property modification. NINGBO INNO PHARMCHEM CO.,LTD. offers Fluorescent Whitening Agent 369, known as Optical Brightener KSB, specifically formulated to enhance the aesthetic and functional properties of various plastic masterbatches. This advanced brightener is crucial for achieving superior whiteness and brightness in plastic products manufactured through masterbatch processes.


Our Fluorescent Whitening Agent 369 is exceptionally effective in whitening masterbatches, where its primary role is to impart a brilliant blue-white fluorescence, effectively masking any inherent yellowness in the base polymer or other additives. This results in a cleaner, brighter final product, significantly improving its visual appeal. Beyond whitening masterbatches, this versatile agent also proves valuable in foaming masterbatches and other functional masterbatches, ensuring consistent color and brightness even in complex formulations.


A key advantage of integrating Optical Brightener KSB into masterbatch formulations is its excellent heat and light resistance. Masterbatch production often involves high temperatures, and finished plastic products are frequently exposed to light. Our FWA 369 maintains its whitening efficacy under these conditions, ensuring long-lasting color stability and preventing yellowing over time. This makes it a reliable choice for manufacturers who prioritize product durability and aesthetics. For those seeking a reputable whitening masterbatches supplier, NINGBO INNO PHARMCHEM CO.,LTD. provides a high-purity (≥99%) and consistent product.


The efficient performance and low dosage requirement of Fluorescent Whitening Agent 369 contribute to its cost-effectiveness in masterbatch production. Its good compatibility with various polymers and other masterbatch additives ensures a seamless integration, leading to uniform dispersion and consistent results. By choosing NINGBO INNO PHARMCHEM CO.,LTD. as your partner, you gain access to premium chemical solutions that enhance the quality and competitiveness of your plastic products.
