Ground Calcium Carbonate(GCC)
Ground Calcium Carbonate(GCC) is usually got by grinding natural carbonate minerals such as calcite, marble and limestone. It is a kind of common powdery inorganic fillers, characterized by high purity, big inertia and excellent thermal stability. GCC never decomposes below 400℃. Besides, it has advantages such as high whiteness, low oil absorption, low refractive index, low hardness, low abrasion value and good dispersion. GCC is soft, dry / water-free, non-toxic, tasteless and odorless. In terms of granularity, GCC can be classified into ordinary GCC, ultrafine GCC, wet-grinding ultrafine GCC and surface-modified ultrafine GCC.
