Ceramic Fibre Bulk

Ceramic Fibre Bulk

STD/Cera: Refractory fibre made from alumina and silica.
AZS/Cerachem: Refractory fibre made from Alumina, Silica and Zironia. All above fibres are resistant to chemical attack, except for hydrofluoric and phosphoric acids and strong alkalies.

Applications

  • Packing material for temporary repair of insulation.
  • Raw material for the manufacturing finished products such as Boards, Shapes, Paper, and Yarn etc.
  • Precursor for engineered fibres.
  • Expansion joints, Patching and emergency repairs in furnaces, Boilers, Heaters etc.
  • Loose insulating fill for crowns and walls of kilns and furnaces.

Availability

  • All Bulk fibres are delivered in 20 Kgs / 25 Kgs bags (or) in cartons of 16 Kgs.

features

  • Excellent Thermal stability resists devitrification at.' high Temperature.' Low thermal conductivity.' Excellent thermal shock resistance.' Excellent chemical stability.' High resiliency.' Good sound absorption.' Low heat storage capacity.
