Most recently, Omya has developed an innovative solution for adding calcium carbonate directly at the extruder, thus allowing higher loadings.

Pipes & fittings (PVC and polyolefin)

Omya's range of calcium carbonates (Omyalite and Omyacarb) is unparalleled, covers the entire spectrum of applications for pipes and fittings and has the following benefits:

  • Improved processing (reduced cooling time)
  • Reduced cycle time (fittings)
  • Higher ring stiffness
  • Mechanical requirements for PVC pressure pipes
  • Homogeneous foam structure (structured wall pipes)
  • Higher elastic modulus


  • Profiles & sidings

    Adding more Hydrocarb to PVC profiles and sidings can yield substantial benefits. By choosing the right calcium carbonate, the process can benefit from:
  • Higher impact strength
  • Better gloss
  • Superior surface finish
  • Good processing at high loadings


  • Specialty chemicals

    Our offering is completed by:
  • Impact modifiers
  • Pigments
  • Lubricants and stabilizers
