Ceramic fiber paper is a thin, flexible, high-temperature insulation material made from ceramic fibers. It is produced by forming a sheet of ceramic fibers, which is then mechanically needled to increase its strength and flexibility. Ceramic fiber paper is commonly used in high-temperature applications, such as furnace linings, as well as for gasket and seal applications.
Ceramic fiber paper is a type of high-temperature insulation material that is made from ceramic fibers. It is a thin and flexible sheet that can be easily cut or shaped to fit various industrial applications that require high-temperature insulation.
The paper is composed of refractory ceramic fibers that are randomly intertwined and bonded with a binder to form a strong and flexible sheet. The fibers used in ceramic fiber paper are typically made from alumina-silica materials, but may also contain zirconia, chromia, or other refractory oxides.
Ceramic fiber paper is known for its excellent thermal insulation properties, with high resistance to heat transfer and low thermal conductivity. It can withstand temperatures of up to 2300°F (1260°C) and is commonly used in applications that require high-temperature insulation, such as furnaces, kilns, boilers, and high-temperature pipelines.
Ceramic fiber paper is also lightweight, easy to handle, and has good chemical resistance. It is available in various thicknesses, densities, and sizes to meet specific insulation requirements. Additionally, it is non-flammable and has low heat storage capacity, which makes it an ideal insulation material for high-temperature environments.
