Fiber-Grade Anatase Titanium Dioxide is specially designed for delustering applications in synthetic fibers such as nylon-6, nylon-66, and polyester (PET). Its high whiteness, strong light scattering, and excellent matting performance ensure superior fiber appearance and consistent quality. Advanced inorganic (Si, Al, P, Mn) and organic surface treatments enhance weatherability, yellowing resistance, and dispersion stability, making it ideal for high-performance fiber production. This TiO₂ grade is widely used by fiber manufacturers seeking improved delustering efficiency, stable processing, and reliable bulk supply.
