Ceramic Bulk Fibre

Supercera Bulk Fibre
Supercera is a high temperature insulating refractory fibre processed from high purity alumina and silica constituent specially selected for high strength refractoriness and stability even under severe conditions.

Supercera spun texture gives it the added extra of exceptionally long fibres and superior mechanical properties essential to meet service conditions.

Supercera bulk fibres provide superior acoustical benefit in addition to high thermal performance a relevant benefit in process furnaces. Supercera can be handled and worked into expansion joints, wall penetrations and other areas with nominal skills. In specific cases, our application engineers would be happy to assist with heat loss. Surface temperature and heat storage computations.

Salient features

• Low heat storage
• Light weight
• Very low thermal conductivity.
• Resistance to high temperature
• High resilience
• Excellent corrosion resistance
• Resistance to thermal shock
• Excellent resistance to chemical attack (with the exceptions of hydrofluoric and phosphoric acids)

 

Applications
As a resilient fill or packing material in high temperature areas like:

• Burner Openings
• Kiln Insulations
• Furnace patch sealings
• Emergency repairs in refractory
• Glass tanks and glass processing
• Furnace repairs
• Expansion joints
• Fibre boxes.
