SIZAL® CELL MICROPOROUS BOARD 1800°C

SIZAL® CELL MICROPOROUS BOARD

Our Sizal® range is a complete line of thermal insulators that open the way to many industrial or laboratory applications up to temperatures of 1800°C. The mechanical and thermal performance of Sizal® products guarantee substantial savings in terms of energy and costs.

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.

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

Pre-calcination

All Sizal®Cell products can be delivered pre-calcined. Cooking parts at more than 350°C eliminates all traces of organic binders that may be present in the materials. This operation avoids gas emissions and potential pollution during more sensitive applications.

Available formats

  • Boards or semi-boards
  • Customised cuts

Customised parts

Sizal®Cell products have good machinability thanks to their homogeneous structure. We are also equipped with a machine workshop so that these materials can be used for the production of technical parts. Our machining centres are equipped with suction systems, specific cutting tools, and fastening systems for more fragile parts in order to guarantee the best possible quality.
