Glass fiber needle-punched felt

Glass fiber needle-punched felt is produced by cutting long glass fibers into specified lengths, followed by fiber splitting, flocking, and needle-punching processes, resulting in a high‑grade, felt‑like material used for air purification, thermal insulation, soundproofing, and heat preservation. It is a non‑toxic, harmless inorganic material that, unlike traditional glass wool or asbestos products, contains no binders and emits no odors—meaning it neither burns nor produces any smoke. Its unique flexibility facilitates easy trimming and cutting, while posing minimal risk of poisoning or allergic reactions to workers. As such, it stands out as a distinctive, eco‑friendly innovation among existing thermal insulation and sound‑absorbing materials.

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 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.
