Ceramic fiber paper
Ceramic fiber paper, also known as alumina-silica paper or refractory paper, is a lightweight and flexible insulating material made from ceramic fibers. It is similar in composition to ceramic fiber blankets but is processed differently to create a thin, paper-like material
Ceramic Fiber Insulation: Manufacturing Ceramic fiber paper
Ceramic fiber paper is primarily composed of blown ceramic fiber cotton as the main raw material, with a certain proportion of binders, fillers, and auxiliary additives added, processed after pulping, slag removal, and pulp mixing. Ceramic fiber paper features a smooth surface, uniform structure, low thermal conductivity, low density, high tear strength, and high flexibility Curing; Cutting and Packaging:

ceramic fiber insulation paper
Ceramic fiber soft paper is characterized by its strong flexibility, good elasticity, and high tensile strength. Ceramic fiber hard paper is easy to cut and process, has excellent toughness, and exhibits high-temperature compressive strength, making it suitable for use as a sealing and gasket material. Ceramic fiber flame-retardant paper incorporates a certain proportion of flame retardants into the raw material mix, ensuring that it does not support the combustion of organic materials even when used at low temperatures.
