Product description

2 inch ceramic fiber board 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 2 inch ceramic fiber board

Kiln construction: Hot side refractory (replaces fiber blankets), heavy refractory backing, expansion joints;
Light industry: Lining of combustion chambers of industrial and domestic boilers .
Petrochemical industry: High-temperature heating furnaces are lined with heat-getting surface materials.

Advantages of 2 inch ceramic fiber board

●Low heat capacity and low thermal conductivity;

●Non-brittle material, good toughness;

●Accurate size and good flatness performance.

●Superior strength for easy installation and maintenance

●Low fiber shot contents and high resilience

●Low heat storage for high efficiency energy savings
