◎Ceramic fiber vacuum forming wet felt is made of ceramic fiber cotton produced by resistance melting and blowing process as raw material and vacuum forming process.
◎Ceramic fiber vacuum forming wet felt product is a kind of light and flexible refractory fiber heat insulation material, which is composed of high-purity refractory oxide and organic adhesive.
◎Ceramic fiber vacuum forming wet felt not only has excellent properties corresponding to bulk ceramic fiber cotton, but also has good strength and elasticity. It is a multi-functional product. It can be used for expansion joints and high temperature gaskets of kiln and boiler walls. When used as a gasket, its good resistance to molten metal penetration is suitable for ingot bottom plate sealing, stopper core gaskets and aluminum billet casting gaskets.
