Ceramic fiber blanket and ceramic fiber board are both made from ceramic fibers but differ in form and application. Ceramic fiber blankets are flexible, non-woven materials that can be easily cut and shaped to fit various applications. They are typically used for insulation in furnaces, boilers, and other high-temperature equipment. On the other hand, ceramic fiber boards are rigid and have a higher density, making them suitable for applications requiring structural strength and resistance to mechanical wear. They are often used for lining kilns, ovens, and other high-temperature containers. The main difference lies in their physical properties and the specific uses they are designed for.
