CALPREC PA is a precipitated calcium carbonate with scalenohedral morphology. Its particular structure, purity and size distribution curve enable increased whiteness and opacity when it is used as filler in paper.
Calprec PA is also especially suitable in paint formulations as an agent that provides hiding power and as high brightness white pigment and therefore used as titanium dioxide extender.
For its chemical purity it is also used in pharma and food industry.
Calprec PE/PN are a series of precipitated calcium carbonates with aragonitical structure and are used as paper fillers where good opacity value, easy retention and sheet filtrability are needed.
Calprec PE/PN are also recommended for reinforcing purposes in plastic formulations.
