Why is Precipitated Calcium Carbonate (PCC) Preferred in

Precipitated calcium carbonate is the most cost-effective mineral for producing high quality paper and paperboard via substitution of more expensive wood pulp, additives or other minerals. The use of PCC as a filler has been growing at a phenomenal rate since Specialty Minerals’ first satellite facility was installed in 1986.
