Specifications
Ceramic fiber boards made from refractory ceramic fiber, attending inorganic and suitable organic binders, High temp. resistant
Ceramic Fiber Boards Descreption:
ceramic fiber boardare 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
