Ceramic fiber fabrics are primarily used for their heat resistance and thermal insulation properties. They are commonly employed in high-temperature industrial applications such as furnace linings, heat shields, and insulation for boilers and kilns. Additionally, they are used in aerospace for heat protection of spacecraft and missiles, in automotive for exhaust systems, and in construction for fireproofing. They also find use in chemical plants for pipe insulation and in the production of metal and glass due to their ability to withstand extreme temperatures without losing strength.
