The Ceramic Fiber Needle-punching Blanket is made through intensive needle punching processing. The product does not contain any bond or other compositions,and also no slag inclusion content. The intensive needlepunching technics improved the fiber intertexture and the resistance performance against delamination as wellas the tensile strength.It have a good high temperature shrinkage after the heat treatment of 750-950 during the producing. Beside the charicteriatics in common,it have better sound insulation performance and mechanism strength,is easy to machining and install.
