Refined calcium carbonate grades for high-quality PVC profiles with an excellent cost-performance ratio.

Omya has developed a range of innovative solutions with fine-tuned grades to meet the demanding requirements of applications such as PVC window profiles.

Improved performance at a reduced cost

Omya’s Hydrocarb solutions offer significant advantages in the production of PVC profiles, particularly window profiles, as they can be added at much higher levels than regular mineral fillers. 


With dedicated grades for different needs, our products offer improved mechanical properties, such as impact resistance, along with enhanced durability and weather resistance. 


Omya fillers allow better process consistency and higher production output at a reduced cost.

Lower your carbon footprint

Our Hydrocarb® XP is a new generation of calcium carbonate for PVC window profiles, designed to allow a further increase in mineral loading. This not only improves the performance of the profiles but also reduces the overall production cost.


In addition, the use of Hydrocarb® XP in window profiles can lower the overall carbon footprint, as it allows the replacement of a significant proportion of higher carbon footprint materials, such as PVC and lower the need of other additives.

Low carbon footprint of 300kg of CO2 equivalents per ton of surface treated natural ground calcium carbonate


  • High process consistency and production output
  • Total material cost reduction and formulation optimization
