Ceramic fiber board is a new type of refractory insulation material.
It is mainly composed of ceramic fiber, binder and a small amount of additives, of which ceramic fiber is usually inorganic fiber material such as aluminum silicate fiber.
（1）Low thermal conductivity,
（2）Low heat capacity, excellent thermal stability
（3）High thermal shock resistance and compressive strength
（4）Good toughness
（1）Industrial kiln wall linings
（2）High temperature kiln linings
（3）High temperature and high heat equipment insulation
（4）Shipbuilding industry insulation and fire protection
（5）Sound insulation and insulation
