Ceramic Fiber Board
2.Ceramic fiber board is designed for insulation applications experiencing vibration, mechanical stress and erosive forces.
3.Ceramic fiber board can reduce energy costs and cycling times due to high insulating capability,as well as serving to protect refractory surfaces from thermal shock and chemical attack.
