Product description
Ceramic fibre board 25mm is processed by wet vacuum forming process. The strength of this type of product is higher than fiber blanket and vacuum forming felt, and it is suitable for high-temperature fields that require rigid strength of the product.

Application of ceramic fibre board 25mm
Steel industry: expansion joints, backing insulation, insulation sheets and mold insulation;
non-ferrous metal industry: tundish and launder covers for pouring copper and copper-containing alloys;
Ceramic industry: lightweight kiln car structure and hot surface lining of the kiln.
Glass industry: Melt pools are insulated by linings, burner blocks;

Advantages of ceramic fibre board 25mm
●Easy to cut and install, convenient for construction;
●Excellent wind erosion resistance;
●Continuous production, uniform fiber distribution and stable performance;
●Excellent sound absorption and noise reduction
