Product description

High temp ceramic fiber board is made of ceramic fiber cotton produced by resistance furnace injection fiber forming process as raw material and processed by 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 high temp ceramic fiber board

● Kiln backing insulation in petrochemical, metallurgy, ceramics and glass industries;
● Backing insulation of heat treatment kiln;
● Backing insulation for non-ferrous metal industry;
● High temperature reaction and heating equipment backing insulation

Advantages of high temp ceramic fiber board

●Lightweight and low thermal conductivity
●High working temperature resistance and insulation
●Superior strength for easy installation and maintenance
●Low fiber shot contents and high resilience
●Low heat storage for high efficiency energy savings
