Jiuqiang Ceramic Fiber Board are made from Jiuqiang 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 four basic fiber types: Sinoshine Board, classification temperature 1000°C,1150°C, 1260°C, 1400°C.

Smooth surface

Low impurity, and average bulk density and thickness

Excellent mechanical strength and structural strength

Low thermal conductivity

Low shrinkage

Resistant airspeed eroding
