Ceramic fiber products are a class of high-temperature insulation materials. The main types include ceramic fiber blankets, boards, ropes, modules, and paper. Ceramic fiber blankets are flexible and used for thermal insulation in various applications. Boards are rigid and often used for structural components. Ropes are used for sealing and insulation in high-temperature environments. Modules are pre-cut shapes for specific applications, and paper is used for wrapping and insulation in lower temperature applications. Each type is chosen based on the specific needs of the application, such as temperature resistance, flexibility, and structural integrity.
