Nanoporous insulation

Nanoporous insulation

The high insulating capacity of nanomaterials comes from their composition of nanoporous ceramic particles. There are only temporary contacts between these particles and the surface ratio is the lowest possible. As a result, the thermal conduction between solid particles is reduced to a minimum. Nanopores also limit convective heat transfer.

All these characteristics make this type of material more efficient than conventional insulating materials such as mineral fibres, refractory bricks and other inorganic products.

This product consists of silica SiO2 (~80%), silicon carbide SiC (~15%) and opacifiers (TiO2 or ZrO2). Nano T is light and powdery and is available as pressure-injection boards.

Main properties of Nano T

  • Usage temperature 950 to 1050°C
  • Very low thermal conduction, from 0.021 to 0.040 W/mK
  • Good machinability for shaping parts
  • Reinforcement by PE film, aluminium foil and more available
  • Class A1 flame protection
  • Thermal shock resistance
  • Excluded from all carcinogenic classifications
  • Stored as a non-hazardous and non-pollutant product
