Refractory Alumina Foam

SIZAL-Cell® is a range of non-fibrous insulation products manufactured from alumina microspheres. Ultra-light, SIZAL-Cell® is designed for high-temperature applications up to 1800°C.

Ceramic foam board

The main component of the insulation is a microsphere made from alumina. An exclusive and innovative process allows the industrial production of this unique element. The internal structure of the cell is a honeycomb-like thread that ensures the mechanical quality of the insulation, whatever the temperature of use. A specific binder means the assembly is homogeneous - this particular construction is light and porous and, consequently, insulating and mechanically efficient.

Main properties

• Guaranteed use up to 1800°C.
• Effective in all atmospheres, including reducing or oxidising atmospheres.
• Low thermal conductivity
• Low density, ultra-light insulation, easy to use
• Long life, no shrinkage or distortion, no decrease in quality and performance over time.
• Excellent resistance to thermal shock. Suitable for repeated and rapid hot and cold cycles, allowing production to increase without premature wear to the furnace lining
• Good resistance to abrasion and burner gas flows.
• Stabilised chemical composition allowing a wide range of applications, with no pollution to the furnace atmosphere.
• Free from fibres and organic binders, and safe and environmentally friendly
• No carcinogenic classification in accordance with regulation EC No. 1907/2006 REACH.

Applications 

• Insulation panels for industrial or laboratory installations
• Furnace linings (electric and gas)
• Furnace, burner or turbine components.
• Mechanical parts, part supports, and more.
• Repairs
