By Function
What the mineral does in your formulation.
Industries describe where calcium carbonate goes; applications describe what it does when it gets there. Browse by function to find the grade that solves your problem.
| Application | What our GCC delivers | Recommended series |
|---|---|---|
| Plastics & Masterbatch | Filler for PE/PP masterbatch, film and injection molding | Coated |
| PVC Pipes & Profiles | Coated grades for improved processing and surface finish | Coated |
| Paints & Coatings | High-brightness extender pigment (97% brightness) | Uncoated |
| Rubber & Cables | Functional filler — adds body, depending on the compound | Coated / Uncoated |
| Paper | Filler and coating material for some paper grades | Uncoated |
| Adhesives, Sealants & Construction | Rheology control and cost optimization | Uncoated / Coated |
Functional Roles
Five jobs. One mineral.
Volume filler
Replaces more expensive polymer or binder volume in PE, PP and PVC systems, helping reduce formulation cost. The loading that remains workable depends on the system and should be confirmed by trial.
Extender pigment
Extends premium white pigments in paints and coatings. At 97% brightness, our GCC holds the film's whiteness while lowering the cost per liter.
Functional filler
Adds body and can support stiffness and dimensional stability in rubber and some cable compounds, depending on the formulation. It is not a direct substitute for carbon black or silica.
Rheology modifier
Helps control viscosity, body and sag resistance in adhesives, sealants and building compounds. A consistent PSD supports consistent flow behaviour.
Paper filler & coating pigment
Fills the sheet and coats the surface — raising whiteness, opacity and printability while reducing fiber consumption.
