Product introduction of ceramic fiber board
Ceramic fiber boards are plates made of refractory material called aluminum silicate fiber boards. It is a fiber insulation system that supports the strength of the desk, and has rigidity more than the fiber blanket and felt. The main raw material is coke and aluminum oxide powder.
Advantages of ceramic fiber board
An excellent performance
Low heat capacity, low thermal conductivity
In non brittle materials, sticky
Accurate in size
High withstand strength and long life
Easy to install and easy to cut
Continuous production, uniform fiber distribution, stable performance.
