View MoreA fluorescent brightener–free additive is a plastic additive that achieves whitening without relying on optical reflection. It works through physical regulation, neutralizing yellowish impurities and providing coverage to create a whiter, brighter appearance.
Unlike traditional fluorescent brighteners that depend on UV light to enhance whiteness, this solution is not limited by lighting conditions. It improves the material's natural whiteness while offering heat resistance, light stability, and UV resistance to reduce yellowing and extend durability.
Our product features good dispersion and is suitable for PVC, PE, PP, PET, ABS, and high-temperature nylon. It remains stable during processing, resists UV-induced aging, and maintains long-lasting whiteness with high purity and minimal color impurities, helping improve both appearance and service life.
