High temperature wool blankets

ALSIFLEX 1600 blankets

FURMATS as authorized market partner of PROMAT offer their High temperature wool blankets, we offer ALSIFLEX blankets. ALSIFLEX®-1600 is a polychrystalline aluminium oxide wool.

The blankets are needled from both sides and produced in different thicknesses and bulk densities

advantages

  • lightweight and flexible
  • low thermal conductivity and heat storage
  • high thermal and chemical resistance
  • high thermal shock resistance
  • easy to work
  • electrically non-conductive
  • numerous delivery forms
  • prefabricated building components and cut sections

Application areas

HEAVY INDUSTRY                                                                  

ALSIFLEX® blankets are used for the termal insulation of high-temperature plants in numerous industries.

Examples:

  • fibre linings in industrial furnaces in layered construction or module systems, such as bogie hearth furnaces, bell furnaces, forging furnaces, tunnel kilns, regenerative thermal oxidizer and regenerative afterburning plants
  • expansion joint material
  • thermal insulation of welded seams
  • arch insulation of tunnel kilns and glass melting tanks
  • Due to the low bulk densities and the almost unlimited thermal shock resistance, ALSIFLEX® is used especially in plants that are only operated periodically.
