Ceramic Fiber Board

Ceramic fiber fireproof board is made from refractory ceramic fiber, attending inorganic, and suitable organic binders. The mixture is vacuum processed into boards that keep good mechanical strengthen after heating.

The ceramic fiber fireproof board offers excellent thermal and physical stability, cold handling strength, and corrosion resistance. They are lightweight, resilient, and able to contact with flame directly. They are often used in duct insulation, expansion joints, flue & chimney linings, furnace, kiln & boiler face, and back up insulation for hard refractory.
