Bulk Fibre

DESCRIPTION

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.

FEATURES

 Excellent Thermal stability :resist devitrification at high Temperature
 Low thermal conductivity
 Excellent thermal shock resistance
 Excellent chemical stability
 High resiliency
 Good sound absorption
 Low heat storage capacity

CLASSIFICATION TEMPERATURE

 STD : 1260 ° C
 AZS : 1425 ° C
 CERA : 1260 ° C
 CERACHEM : 1425 ° C
The Maximum use temperature depends on the application.
In case of doubt, refer to MMTCL Technical service for advice.

APPLICATIONS

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

AVAILABILITY & PACKAGING

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