Insulation properties
Exceptional insulation properties.
Temperature resistance
High temperature resistance up to 1400 °C.
Temperature change
High resistance to temperature changes.
PRODUCT TYPE
Mats (blankets) made of high temperature wool are needled lightweight mats made of biosoluble (AES) high temperature wool (HTW) and provide 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 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
Alkaline earth silicate fiber high temperature wool (AES Alkaline Earth Silicate Wool) consist of a mix of amorphous fibers, which are melted and then rapidly solidified using a combination of silica SiO2 and calcium oxide (CaO) with or without magnesium oxide (MgO). The fiber can be obtained by refining with other additives or a change in the material mix (addition of zirconium oxide (ZrO2) have a temperature resistance of up to 1260 ° C.
