PROPERTIES

Our alkaline earth silicate fiber mat 1200 ° C offers advanced physical properties, which both increase thermal efficiency and improve handling. These needled mats combine our unique know-how with proven technology to produce the best alkaline earth silicate fiber mat with low bio-persistence currently available. Our alkaline earth silicate fiber mats 1200 ° C are made from alkaline earth silicate wool (AES wool).

advantages

  • Exceptional insulation properties
  • High temperature resistance (up to 1200 ° C)
  • Resistance to temperature changes
  • High tensile strength & elasticity
  • Lightweight
  • Excellent flexibility
  • Good sound insulation

PRODUCT TYPE

Mats (blankets) made of high temperature wool are needled lightweight mats made of ceramic (ASW / RCF) or biosoluble (AES) high temperature wool (HTW) and represent an effective solution for a wide range of thermal insulation applications. They are characterized by excellent insulating properties, high resistance to chemicals, elasticity and dimensional stability. They are exclusively inorganic and therefore no smoke or vapors are generated when exposed to heat. They are available in a wide range of densities and thickness combinations, making them one of the most versatile product groups on the market.

MATERIAL

Alkaline earth silicate fiber high temperature wool (AES Alkaline Earth Silicate Wool) consist of a mix of amorphous fibers that melt and then rapidly solidify a combination of silicon dioxide SiO2 and calcium oxide (CaO) with or without magnesium oxide (MgO). The fiber can be refined with other additives or a change in the material mix (addition of zirconium oxide (ZrO2) have a temperature resistance of up to 1260 ° C.
