The main types of ceramic fiber insulation board include: 1) Standard Ceramic Fiber Board, which is used for general thermal insulation applications; 2) High-Alumina Ceramic Fiber Board, known for its high-temperature resistance and strength; 3) Alkaline-Resistant Ceramic Fiber Board, designed to resist alkaline environments; 4) Low Biopersistent Ceramic Fiber Board, which is less likely to cause health issues due to fiber release; and 5) High-Temperature Ceramic Fiber Board, used in extreme temperature conditions. Each type is selected based on specific application requirements, such as temperature range, chemical resistance, and physical strength.
