Ceramic Fiber Blanket

Ceramic Fiber Blanket Line

The ceramic fiber blanket is manufactured from high purity alumino-silicate fibrous wool, and free of any asbestos, suitable for insulating material of high temperature tubes, the material of wall lines and back lines of industrial furnace, the sealing and insulating material of expanded gaps of furnace wall, furnace door, furnace top lid, ect., with properties of flexible and easy to install, low thermal conductivity, good tensile strength, chemical stability and light weight, etc..

The wool is non-combustible.
