Ceramic Fiber Paper

Ceramic fiber paper is also called aluminum silicate fiber paper， Ceramic fiber paper is a type of insulation made from ceramic fibers. It is a lightweight, flexible, and non-combustible material that can withstand high temperatures. Ceramic fiber paper is made from alumina, silica, and other materials that are melted and then spun into fibers. The fibers are then bonded with a resin to form a paper-like material. Ceramic fiber paper is available in various thicknesses, densities, and temperature ratings.
