Precipitated Calcium Carbonate (PCC) is used as a mineral load to improve the rheology and mechanical resistance of the plastic.

In the last two centuries, continuous R+D on new molecules and systems of polymerization has led to a growth in the number of materials based on the chemistry of carbon-based chemicals. Thousands of types with different properties mean that plastic today has a huge number of applications, becoming an essential part of day-to-day life in developed societies.
