Ceramic Fiber Vacuum Formed Shapes

(1)Ceramic fiber vacuum formed shapes are made of high-quality ceramic fiber bulk by adopting the technique of vacuum forming.(2)All formed shapes have a lower shrinkage within applicable temperature, can maintain the characteristics such as insulation,lightweight etc. (3)During the period of using the products,they wont eroded by lots of molten metal.
