Ceramic Fiber Bulk (Standard)
Catalog NO.: AIMRSE-CER-009 Category: Ceramic Fiber Blanket / Bulk
Ceramic Fiber Bulk is a high-efficiency, lightweight thermal insulation material made from high-purity alumina, silica, and zirconium oxide minerals through high-temperature melting and then processed using a blowing or spinning process. It has a clean, white appearance and a microstructure of interwoven fibers. It possesses excellent physical properties such as high-temperature resistance, low thermal conductivity, and strong thermal shock resistance, as well as advantages such as good chemical stability and excellent sound absorption. The fiber can be further processed into fiber blankets, boards, paper, cloth, ropes, and other products.

◈ Low Thermal Conductivity: Minimizes heat transfer to maximize energy efficiency.
◈ Low Heat Storage: Allows for rapid heating and cooling cycles, increasing kiln productivity.
◈ Thermal Shock Resistance: Maintains structural integrity under sudden temperature fluctuations.
◈ Chemical Stability: Resists most corrosive agents, except hydrofluoric and phosphoric acids.
◈ Excellent Sound Absorption: Provides significant acoustic dampening in high-heat machinery.
◈ Flexible Application: Easy to pack into intricate shapes and voids where rigid boards cannot fit.
Raw Material: Feedstock for ceramic fiber paper, boards, vacuum-formed shapes, and textiles.
Expansion Joints: Packing for expansion joints in industrial furnaces and boilers.
High-Temp Infill: Loose fill insulation for furnace wall cavities, kiln cars, and roof seals.
Filtration: High-temperature gas and liquid filtration media.
Emergency Repair: Quick-fix thermal insulation for industrial heat leaks.
