*Smooth surface
*Average density and thickness
*Low thermal conductivity
*Low shrinkage and low density
WHT Ceramic Fiber Board are made from high pure ceramic fiber by advanced vacuum formed machines, which make WHT board own more mechanical strength and average density compared with those boards formed by traditional machine. WHT Ceramic Fiber Boards are classified as below: 1000°C,1260°C,1400°C,1500°C,1600°C,1700°C,1800°C.CharacteristicsTypical ApplicationsStandard Dimension1000×600×6-100mm , 1000×1200×25-100mm900×600×6-100mm, 900×1200×25-100mm1100×700×10-100mm Chemical & Physical Data
