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.

Ceramic Fiber Composite Insulation Board

Ceramic Fiber Composite Insulation Board

The company’s newly developed ceramic fiber composite insulation panel employs high-performance aerogel insulation material and functional materials with thermal shielding properties, combined with binders and various inorganic components. Reinforced with high‑temperature‑resistant ceramic fibers, it is manufactured using a specialized process. This insulation material features an ultrafine nanoporous structure that significantly reduces solid‑state heat conduction, while its dense network of nanoscale pores effectively suppresses convective heat transfer by gas molecules. Coupled with the absorption and reflection of thermal radiation by the functional additives, the material achieves a thermal conductivity of approximately 0.030 W/m·K at 600°C—2 to 10 times lower than that of commonly used insulation materials today.

Glass fiber needle-punched felt

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.

    What is ceramic fiber?

    Ceramic fiber is a fibrous, lightweight refractory material that boasts numerous advantages, including light weight, high-temperature resistance, excellent thermal stability, low thermal conductivity, low specific heat, and resistance to mechanical vibration. Consequently, it has found widespread application across industries such as machinery, metallurgy, chemical processing, petroleum, ceramics, glass, and electronics. In recent years, driven by the continuous rise in global energy prices, energy conservation has become a national strategic priority in China. Against this backdrop, ceramic fiber—capable of delivering energy savings of 10–30% compared with traditional refractories like insulating bricks and castables—has seen increasingly broad adoption within the Chinese market, with very promising prospects for future development.
