Ceramic Fiber Block
The block fiber in a pre-compression form is beneficial to decrease the volume change, and enhances the insulation performance.

  • Good chemical stability
  • Good thermal stability
  • Low conductivity
  • Low heat capacity
  • High heat reflectivity

Max. service temperature:
1260℃, 1430℃, 1600℃

Standard size:
300×15×50, 75
200×200×50, 75
300×300×150~300

Typical Applications:
Insulation veneering of furnaces in such industries as steel, non-ferrous, petrochemical, ceramic.
