Precipitated Calcium Carbonate – inpcc
When comparing to standard ground calcium carbonate (GCC), precipitated calcium carbonate (PCC) can be distinguished for:
- the possibility to achieve smaller and more uniform particle size
- more stable and narrower granulometric distribution
- lower abrasivity
- higher specific surface
- highest chemical purity
- defined rheological properties
Depends on application, we can offer two different types of precipitated calcium carbonate: Uncoated PCC and Coated PCC.
Uncoated PCC
Uncoated PCC (inpcc Calprec PA, inpcc Calprec PA-170E) characterized by scalenohedral particle shape and micrometric size.
Outstanding properties
- outstanding whiteness and high brightness
- high chemical purity
- effective titanium dioxide extender
- porosity
- source of calcium
Applications
- decorative paints
- paper
- plastics (PVC Plastisols)
- pharma
- food (inpcc Calprec PA-170E)
inpcc Calprec PA-170E
inpcc Calprec PA-170E can be used in various food applications meeting the standard requirements as E170 food additive. It is used as source of calcium (toothpastes, supplement pils), anti-acidic agent in the production of wine or as whitener in the production of chockolates or bakery.
Coated PCC
Coated PCC (inpcc Calprec PR; PR-W;PR-2E; PR-G; SEAL) characterized by spherical or cubic particle shape and nanometric size.
Outstanding properties
- effective rheology modifier
- provide good mechanical and anti-sedimentation properties
- increases impact resistance and stiffness in rigid PVC
- influences on surface appearance by increasing a gloss level
Applications
- adhesives & sealants
- plastics
- rubber
- printing Inks
