Furnace Insulation Refractory Ceramic Fiber Blanket / Board With
Alumina Silica Fibers
Description:
ceramic fiber board is a lightweight refractory material processed
with alumina-silica fibers for applications at temperatures up to
1430℃(2600℉)
Ceramic fiber board is a vacuum formed product that resists higher
gas velocities than ceramic fiber blanket,it is ideal for
furnace,boiler duct and stack lining due to its low thermal
conductivity and low heat storage allowing shorter cycle times and
quicker access for maintenance
