Welcome to Imerys Performance Minerals

Glomax Series

Glomax® Series For electrical insulation in medium to high voltage cables and improved processing in extruded parts

  • High stability and purity
  • Highly insulating
  • Low moisture pick-up
  • Excellent processability
  • Low compression set
  • Chemical resistance

Imerys Glomax® is a high purity calcined kaolin designed to provide low conductivity for medium and high voltage electrical applications where volume resistivity is crucial and low tan delta is required.

Wire & Cable

Glomax® provides excellent insulation properties in medium and high voltage power cables

With its unique particle structure, Glomax imparts high modulus, tensile strength, tear and abrasion properties in elastomers. Improved processing performance may allow higher filler loading in aqueous and non-aqueous systems leading to cost and processability optimization. 

Due to its low moisture pick-up, Glomax is an excellent choice for guaranteeing insulation properties under wet operating conditions. 

Glomax® improves compression set, making it suitable for the production of rubber cable sheathing of flexible cable. 

When used in partial replacement of ATH or MDH in halogen-free cables, Glomax provides superior flame retardancy, abrasion and oil resistance while maintaining superior electrical properties.

EPDM extrusion

Glomax® is a valuable processing aid in extruded and calendered rubber where it provides a smooth finish and excellent dimensional control due to the low die swell.

Glomax® is recommended for:

  • Wire and cable
  • EPDM/EPR extruded profiles
  • Pharmaceutical rubber
  • Mechanical rubber compounds

Series Range

  • Glomax® LL
  • Glomax® LX
