PROPERTIES

Our Ceramic Fiber Mat 1250°C stands for needled lightweight mats made of ceramic fiberfrax and effective solutions for a wide range of thermal insulation applications. Our ceramic fiber mats 1250°C are characterized by excellent insulating properties, high resistance to chemicals, elasticity and dimensional stability. They are exclusively inorganic and thus achieve their dimensional stability, elasticity and thermal insulation properties in many applications without the appearance of smoke or fumes. They are available in a wide range of densities and thickness combinations, making them one of the most versatile product groups on the market.

APPLICATION

  • High temperature resistance
  • Low thermal conductivity & heat storage
  • High tensile strength & elasticity
  • Thermal shock resistance & durability
        to chemicals
  • Good sound absorption

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 provide an effective solution for a wide range of thermal insulation applications. They feature excellent insulating properties, high resistance to chemicals, elasticity and dimensional stability. They are exclusively inorganic and therefore do not generate smoke or fumes 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

High temperature wool made of ceramic fibersalso known as ASW (Aluminum Silicate Wool) or RCF (Refractory Ceramic Fibre), have been used for years as the standard fibre type for insulation solutions up to 1250 °C. Consisting of a mix of aluminium oxide (Al2O3) and silica (SiO 2)2), the fibers offer good chemical & mechanical properties in addition to high temperature resistance.
