Ceramic fiber felt

Made by vacuum forming using ceramic fiber cotton—produced via resistance‑melting and jet‑spinning processes—as the primary raw material, this is a lightweight, flexible refractory fiber insulation material. In addition to inheriting the excellent properties of loose‑type ceramic fiber cotton, it also boasts superior strength and elasticity, making it ideal for expansion joints in furnace and boiler walls as well as for high‑temperature gaskets.

Ceramic fiber felt

Manufactured via vacuum forming using ceramic fiber wool—produced by resistance‑melting and jet‑spinning processes—as the primary raw material, this product is a lightweight, flexible refractory fiber insulation. In addition to inheriting the excellent properties of loose‑type ceramic fiber wool, it also exhibits superior strength and elasticity, making it well suited for expansion joints in furnace and boiler walls as well as high‑temperature gaskets. When used as a gasket, its outstanding resistance to molten metal penetration makes it ideal for sealing ingot ladle bottoms, stopper‑rod core gaskets, and aluminum billet casting gaskets.
