Description
Ceramic fiber board uses non-brittle material, therefore it has good tenacity, high compressive strength, good flatness and mechanical pr °Cess 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.
