Mainly used for products in industrial high-temperature applications
High chemical resistance
Typically used from 1100°F (600°C) to 2600°F (1430°C)
RCFs are defined as:
Amorphous man-made fibers produced from the melting and blowing or spinning of calcined kaolin clay or a combination of alumina (Al203) and silica (SiO2). Approximate percentages (by weight) of components are: alumina, 20-80%; silica, 20-80%; and other oxides such as zirconia in lesser amounts.
RCF products are generally used in industrial equipment like furnaces and kilns under critical application conditions, in fire protection and in automotive exhaust systems.
HTIWs are used in industrial equipment such as furnaces and kilns as well as in fire protection systems.
