Product description

High temperature fiber board processed from a combination of high-purity refractory oxides and organic binders. Ceramic fiber vacuum forming felt not only has the excellent properties of bulk ceramic fiber cotton, but also has good strength and elasticity. It is a multi-functional product.

Application of high temperature fiber board

● Steel industry: expansion joints, backing insulation, insulation sheets and mold insulation;
● Light industry: Lining of combustion chambers of industrial and domestic boilers .
● Backing insulation for non-ferrous metal industry;
● High temperature reaction and heating equipment backing insulation

Advantages of high temperature fiber board

●Lightweight and low thermal conductivity
●High working temperature resistance and insulation
●Superior strength for easy installation and maintenance
●Easy to cut and install, convenient for construction;
●Continuous production, uniform fiber distribution and stable performance;
