Suzorite Range

Suzorite® range For controlled dimensional stability in wet-room and fire-resistant fiber cement and silicate board

  • Dimensional stability
  • Controlled thermal shrinkage
  • Improved board integrity
  • Fire resistance

Imerys Suzorite low-density phlogopite micas are suitable for fiber cement board used in wet room applications. 

Used in combination with our Nyad® wollastonite, Suzorite® micas can be used to control dimensional stability, thermal shrinkage and board integrity in fiber cement and silicate board to meet strict dimensional stability performance criteria for use in wet rooms and where fire-resistant applications are required. 

Key properties and benefits:

  • Synergistic effect with wollastonite
  • Improved thermal shrinkage
  • Hydric movement control


  • Fiber cement board 
  • Silicate board
  • Wet room applications
  • Fire-resistant applications

We recommend our Suzorite® 20 S and Suzorite® 30 S low bulk density phlogopite micas for these applications.

We offer a full range of custom formulation and technical and process support services to help you match the right mineral grade to your application requirement.
