产品描述

Laurel 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
