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.
