DR-2589 is a specially designed plastic Rutile grade with good durability. DR-2589 specialties are super bluish undertone, outstanding lightness in coloring and excellent opacity.   The special inorganic treatment of dense amorphous silica and alumina protect the surface of Tio2 from acting with polymers or additives. The organic surface treatment ensures DR-2589 outstanding dispersion, processibility and low hygroscopicity in plastics production. The new treatment technology of DR-2589 can effectively improve the heat resistance, light fastness and weathering of plastics and keep them free from UV lights.
