Product Benefits

The quality and consistency of the raw materials and the properties of the plastic clay can have a major effect on the quality of ceramic insulators. It is imperative to use high quality plastic clay that is fit for the purpose with the correct combination of properties, mixed layer illite-smectite is the preferred clay mineral.

Clay can provide:

  • Insulation from high voltage currents
  • Superior forming performance
  • Excellent strength & plasticity
  • Low residues
  • Low carbon
  • Low iron levels
  • High Alumina
