PRODUCT TYPE
Mats (blankets) made of high temperature wool are needled lightweight mats made of ceramic (ASW/RCF) 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
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 1260 ° 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.
By further refining the fiber with zirconium oxide (ZiO2), a temperature resistance of up to 1400 ° C can be achieved.
