Ceramic Fiber Blanket

1.Ceramic fiber blanket is high strength,needled insulating blanket that is made from ceramic fiber cotton.
2.The combination of long spun fibers and needling operation produce tough,resilient and strong blankets,which resist tearing both before and after heating. 
3.The ceramic blanket is completely inorganic and available in a variety of temperature grades,densities,and sizes.
4.The ceramic blanket can be folded,compressed and encapsulated to produce modules.
