Ceramic Fiber Board

YESOWOOL vacuum forming ceramic fiber board made of YESO ceramic fiber with a small amount of binder through vacuum forming technique with good mechanical strength even after heating with several grades of 1000 ℃, 1260 ℃, 1400 ℃, 1500 ℃, 1600 ℃, 1700 ℃, 1800 ℃. YESOWOOL vacuum forming ceramic fiber board with high strength and resistance to airflow erosion can be directly used as hot surface furnace lining materials.YESOWOOL Hydrophobic vacuum forming ceramic fiber board after special process treatment with good hydrophobic performance in the construction process and high moisture conditions.YESOWOOL inorganic boards are made of YESO ceramic fiber and inorganic binder by vacuum forming technique which does not contain organic matters and has no pollution gas volatilization when used at high temperature.
