 Ceramic Fiber Board Specifications

ceramic fiber board are made from refractory ceramic fiber, attending inorganic and suitable organic binders. The mixture is vacuum processed into boards or formed shapes that keep good mechanical strength after heating. These products can be manufactured using five basic fiber types: ISOFILE CFB Board, classification temperature 1000°C, 1260°C, 1400°C, 1600°C and 1700°C; and MB millboard, classification temperature 1500°C. ISOFILE CFB can be used for internal lining of furnace with high strength and anti airspeed eroding.

Ceremic fiber board Characteristic

• Smooth surface
• Low impurity, and average bulk density and thickness
• Excellent mechanical strength and structural strength
• Low thermal conductivity
• Low shrinkage

Ceramic Fiber Boards Applications

• Back-up lining of high-temperature industry furnaces.
• Hot-face lining of ceramic kilns, heat-treatment furnaces and other industrial kilns.
• Insulation for furnace door and kiln ca
