Ceramic fiber board and ceramic fiber cloth are both made from ceramic fibers but differ in form and application. Ceramic fiber board is a rigid, flat material that is typically used for insulation in high-temperature environments, such as furnaces and kilns. It offers excellent thermal insulation and resistance to thermal shock. Ceramic fiber cloth, on the other hand, is a flexible material that can be draped or wrapped around objects for insulation. It is often used in applications requiring flexibility and ease of installation, such as pipe insulation or as a thermal barrier in industrial settings. The board is more suitable for structural insulation, while the cloth offers versatility for various shapes and sizes.
