Product description：
◎ Ceramic fiber vacuum forming wet felt, the ceramic fiber cotton produced by resistance melting and spray forming process is used as raw material and made by vacuum forming process.
◎ Ceramic fiber vacuum forming wet felt product is a lightweight, flexible refractory fiber insulation material, a combination of high purity refractory oxide and organic adhesive.
◎ Ceramic fiber vacuum forming wet felt in addition to the corresponding loose ceramic fiber cotton excellent performance, and has good strength and elasticity, is a multi-functional product, can be used for kiln and boiler wall expansion joints and high temperature gaskets. When used as a gasket, its good resistance to molten metal penetration is suitable for ingot bottom plate seals, plug core gaskets, and aluminum billet casting gaskets.
