Description:
Ceramic fiber board uses non-brittle material, therefore it has good tenacity, high compressive strength, good flatness and mechanical process ability. Temperature is 1050°C, 1260°C, 1430°C and it is the ideal material for wall liner and back lining of the heating equipment.
Ceramic Fiber Board
Characteristics:
Flat surface Equal volumetric weight and thickness
Excellent mechanical and structure strength
Low thermal conductivity and low shrinkage
Air-current resistant washing
Typical application:
Heat insulation for back lining of high temperature industrial furnace Heat surface lining materials for porcelain furnace, heat treatment furnace of mechanical and metallurgy and other industrial furnaces.
