CHARACTERISTICS

The Fiberfrax Durablanket product group stands for needled lightweight mats made of ceramic Fiberfrax fibers and effective solutions for a wide range of thermal insulation applications. Fiberfrax Durablanket products 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 areas of application without the occurrence of smoke or vapors. They are available in a large number of density and thickness combinations and thus represent 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 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 large number of density and thickness combinations and thus represent one of the most versatile product groups on the market.

MATERIAL

High temperature wool made of ceramic fibers, also known as ASW (aluminum silicate wool) or RCF (Refractory Ceramic Fiber), have been used for years as the standard fiber type for insulation solutions up to 1250 ° C. Consisting of a mix of aluminum oxide (Al2O3) and silica (SiO 2)2), the fibers offer not only high temperature resistance but also good chemical and mechanical properties.

UNIFRAX®
