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.
