Ground Calcium Carbonate products
Ground Calcium Carbonate (GCC) is produced through mechanical grinding of naturally occurring calcium carbonate rocks. Most Imerys production sites use high brightness marble as the raw material but, at some sites, locally available limestone or chalk is used.
GCC in pigment formulations provides good rheology and high brightness at low cost. Imerys Pigments for Paper has the multi-pigment formulation knowledge to select the best partner pigments to complement GCC, playing to its strengths and avoiding its weaknesses.
Regional Manufacturing Sites
Imerys Pigments for Paper facilities in North and South America, Europe, Asia and Australia produce well over 2 million metric tons per year of ground calcium carbonate for the paper industry. Imerys’ facilities are located in the world's major paper manufacturing regions and are supplied with the finest, pure, white marble from our global reserves.
Imerys GCC plants operate under the strict philosophy of Best Demonstrated Practice and produce GCC to the highest quality standards.
