ImerCarb™ & PolCarb™
- High loading extenders
- Rheological modifiers
- Processability enhancers
Imerys ImerCarb™ and PolCarb™ are fine ground calcium carbonates (GCC) which can be used as high loading extenders in rubber without impacting mechanical properties:
- ImerCarb™ is a range of ground calcium carbonates manufactured from high quality crystalline marble at our Belgian and Italian processing facilities.
- PolCarb™ is a range of ground calcium carbonates produced from our high quality chalk deposits in both the UK and France.
Fine ground carbonates are used in rubber applications as high loading extenders, rheological improvers and processability enhancers.
PolCarb™ and ImerCarb™ are available in both uncoated and surface treated grades.
Surface treatment reduces moisture pickup and improves dispersion in polymer systems.
Used in rubber compounds, ImerCarb™ and PolCarb™:
- Lower compound cost
- Provide electrical insulation
- Modify elasticity
- Improve mold release
ImerCarb™ and PolCarb™ grades are recommended for:
- Cable sheathing and insulation
We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
