Plastics & Rubber-Cables

Coated ultrafine precipitated calcium carbonate (CPCC) improves the processing behavior in rigid PVC and cables formulations.

Benefits using CPCC in plasticised PVC :

  • High surface gloss
  • Smooth surface finish and white scratch marking resistance.
  • Resistance to white flex marking
  • Efficient HCl acid gas absorption.

CPCC is used in both insulation and cable sheathing where it provides a high gloss finish and retained good electrical properties.

The most significant interest concerning the utilisation of CPCC in cable compounds relates to the ability of the high surface area CPCC to effectively retain HCl gas released under a combustion situation. Practical cable formulations have been developed that rely on this high surface area activity of synthetic calcium carbonate for HCl capture and in combination with other additives this allows workable formulations for use in this sector.
