Ceramic fiber blanket

Ceramic fiber blanket
◎ Ceramic fiber blankets are produced continuously and, after needle-punching, feature uniformly interwoven fibers with high tensile strength, containing no binders. ◎ Needle-punched blankets of varying bulk densities and thicknesses offer users a wide range of material options to achieve optimal insulation performance and cost-effectiveness. ◎ Ceramic fiber blankets exhibit excellent resistance to chemical attack (except for hydrofluoric acid, phosphoric acid, and strong alkalis such as Na2O and K2O). ◎ The performance of ceramic fiber blankets is unaffected by oil exposure; their thermal and physical properties can be fully restored upon drying.

Ceramic fiber wet-laid felt

Ceramic fiber wet-laid felt
Ceramic fiber vacuum‑formed wet‑laid felt is manufactured using ceramic fiber wool produced by the resistance‑fused blow‑spinning process, and is shaped via a vacuum‑forming technique. ◎This ceramic fiber vacuum‑formed wet‑laid felt is a lightweight, flexible refractory fiber insulation material, composed of high‑purity refractory oxides combined with an organic binder. ◎In addition to inheriting the excellent properties of its loose‑fill counterpart, this product also exhibits superior strength and elasticity, making it a versatile material. It is suitable for expansion joints in furnace and boiler linings as well as for high‑temperature gaskets. When used as a gasket, its outstanding resistance to molten metal penetration makes it ideal for sealing ingot ladle bottoms, plug‑rod core gaskets, and aluminum billet casting gaskets.
