Ceramic Fiber Board
UWool® Ceramic Fiber Board, also known for aluminum silicate board, is made by adding a small amount of binders into high purity alumina silicate. UWool® Ceramic Fiber Board is made through automation control and continuous production process, with a host of features such as precise size, good flatness, high strength, lightweight, excellent thermal shock resistance and anti-stripping, which can be widely used for insulation in the linings around and at the bottom of kilns, as well as ceramic kilns fire position, craft glass mold and other positions. Temperature varies from 1260℃ (2300℉) to 1430℃ (2600℉). UWool® Ceramic Fiber Board is widely used for refractory and high temperature application such as Industrial furnace wall lining, Back lining material, Furnace masonry expansion joints/door/roof heat insulation seal, High temperature pipe insulation material, Module/folded module processing material, Fireproof coating, Steel industry, Heat treating and annealing furnaces, Furnace door linings and seals, Soaking pit covers and seals, Furnace hot face repairs, Reheat furnaces, Ladle covers, Power generation, Boiler Insulation, Boiler Doors, Reusable Turbine Covers, Pipe Covering, Insulation of Commercial Dryers and Covers, Veneer Over, Existing Refractory, Stress Relieving Furnaces, Glass Furnace Crown Insulation, Fire Protection.
