Precipitated Calcium Carbonate (PCC) in plastic industry


Precipitated Calcium Carbonate (PCC) is used as a mineral filler improving the rheology and mechanical resistance of the plastic.

In the last two centuries, continuous R+D on new molecules and polymerisation systems has led to the expansion of materials based on the chemistry of carbon chemicals. There are thousands of types, properties and benefits of plastic today with an immense number of applications, forming part of the essential way in which society develops day to day.

Cales de Llierca PCC brand, CALPREC®,  is used as a functional filler improving the mechanic properties and appearance of different types of rigid plastic, especially in PVC (whiteness, shine, finish). Unlike other fillers, CALPREC® provides a decrease in the consumption of other additives such as dispersants, impact modifiers and rheology during processing and impact.
