Ceramic Fiber Board

Prime Features:
Ceramic fiber board uses non-brittle material, therefore it has good tenacity, high compressive strength, good flatness and mechanical process ability. It is ideal material for wall liner and back lining of the heating equipments.

Prime Features:
> Flat surface;
> Excellent mechanical and structure strength;
> Equal volumetric weight and thickness;
> Low thermal conductivity and low shrinkage;
> Air-current resistant washing.
