Ceramic fiber sheets are available in several types, each with distinct properties. The main types include Standard Ceramic Fiber Sheets, which are cost-effective and suitable for general thermal insulation; High-Alumina Ceramic Fiber Sheets, known for their high-temperature resistance; Alkaline Earth Ceramic Fiber Sheets, offering better mechanical strength; and High-Purity Ceramic Fiber Sheets, which are resistant to chemical attack and used in severe environments. Each type is chosen based on the specific application's temperature, chemical exposure, and mechanical requirements.
