ceramic fiber bULK


Cera/Cerawool : Refractory fibers made from alumina and silica
Cerachem : Refractory fibers made from Alumina, Silica and Zirconia
The above grade of fibers are impervious to most chemicals except Hydrofluoric & Phosphoric acids and strong alkalies


Bulk Refractory Fiber


  • Raw material for the manufacture of finished products such as Boards, Shapes, Paper & Yarn

  • Expansion joints, Patching and emergency repair in furnaces, boilers, heaters etc

  • Loose insulating fill for crowns, walls of kilns and furnaces

  • Packing material for temporary of insulation

  • Precursor for engineered fibers


  • Excellent thermal stability with good resistance to devitrification at high temperatures
  • Lower thermal conductivity
  • Excellent thermal shock resistance
  • Excellent chemical stability
  • Low heat storage capacity
  • High resiliency
  • Good sound absorption


Cerawool : 1200 ° C
Cera Blanket : 1260° C
Cerachem Blanket : 1425° C
