High Temperature Ceramic fiber cloth

High temperature ceramic fiber cloth, also known as refractory cloth, is a specialized textile material made from ceramic fibers designed to withstand extreme heat and provide thermal insulation in high-temperature applications. Here’s an overview:


  1. Ceramic Fibers: High temperature ceramic fiber cloth is primarily composed of inorganic fibers derived from alumina-silicate or other ceramic materials. These fibers are produced through a process of melting, spinning, and fiberizing the raw materials to create long, thin fibers.

  2. Binders and Additives: In some cases, binders or additives may be added to the ceramic fibers to enhance certain properties, such as flexibility, tensile strength, or chemical resistance.

Key Features:

  1. Extreme Heat Resistance: Ceramic fiber cloth is capable of withstanding temperatures exceeding 1000°C (1832°F) and can withstand short-term exposure to even higher temperatures, making it suitable for use in extreme heat environments such as furnaces, kilns, and industrial ovens.

  2. Thermal Insulation: These cloths provide excellent thermal insulation properties, minimizing heat transfer and maintaining temperature stability in high-temperature equipment and processes.

  3. Low Thermal Conductivity: Ceramic fiber cloth has low thermal conductivity, helping to reduce heat loss and improve energy efficiency in various industrial applications.

  4. Lightweight and Flexible: Despite their high heat resistance, ceramic fiber cloths are lightweight and flexible, making them easy to handle, cut, and install in tight spaces or complex shapes.

  5. Chemical Resistance: Ceramic fiber cloths exhibit good resistance to most chemicals, acids, alkalis, and solvents, making them suitable for use in chemical processing, petrochemical, and power generation industries.

  6. Abrasion Resistance: These cloths are highly resistant to abrasion, wear, and mechanical stresses, ensuring long-term durability and performance in harsh operating conditions.

  7. Non-Flammable: Ceramic fiber cloth is inherently non-combustible and does not support combustion, making it highly resistant to fire and heat. It is often used in fireproofing applications and as a protective barrier against flames and sparks.


  1. Insulation: Ceramic fiber cloth is used for thermal insulation in various high-temperature applications, including lining for furnaces, kilns, boilers, and heat treatment equipment to prevent heat loss and improve energy efficiency.

  2. Expansion Joints: It is used in expansion joint seals and gaskets to accommodate thermal expansion and contraction in piping systems, ducts, and exhaust systems in industrial plants and power generation facilities.

  3. Sealing and Wrapping: Ceramic fiber cloth is used for sealing, wrapping, and packing applications in high-temperature environments, such as door seals, furnace seals, and insulation blankets for boilers and turbines.

  4. Fireproofing: It is used in fireproofing applications for manufacturing fire curtains, fire doors, and fire blankets to contain fires, prevent heat transfer, and protect structures and personnel in buildings, ships, and industrial facilities.

  5. Welding Protection: Ceramic fiber cloth is used as a protective barrier for welding curtains, blankets, and shields to prevent sparks, slag, and spatter from causing damage or injury in welding and metal fabrication operations.

  6. Gaskets and Seals: It is used for manufacturing high-temperature gaskets, seals, and packings for valves, pumps, and other equipment in chemical processing, oil & gas, and power generation industries.

  7. Insulation Jackets: Ceramic fiber cloth is used as the outer shell for insulation jackets and covers for hot surfaces, equipment, and piping to provide thermal insulation and personnel protection in industrial plants and refineries.

Overall, high temperature ceramic fiber cloth is a versatile and essential material in various industries where thermal insulation, fire resistance, and durability are critical requirements. Its exceptional heat resistance, thermal insulation properties, and flexibility make it an indispensable component in numerous industrial processes and safety applications.
