Nano Activated Calcium Carbonate CCR (also called activated nano calcium carbonate or surface-treated nano CaCO₃) is a high-performance functional filler produced by precipitation and then surface-modified with fatty acid / stearic acid.
It combines nano-scale particle size, high specific surface area, and excellent polymer compatibility, making it ideal for manufacturers who want to improve mechanical properties while reducing formulation cost.
