Alumino-silicate needle-punched blanket (ceramic fiber blanket), asbestos-free eco-friendly refractory material, double-sided needlepunched process with high tensile strength and no shedding; available in standard / high-purity / zirconium-containing multi-temperature models, maximum temperature resistance up to 140°C, Class A fireproof insulation, suitable for boilers, kilns, exhaust ducts, and high-temperature equipment insulation; multiple thicknesses and densities in stock, supporting custom cutting full rolls, and aluminum foil composite customization. [Product Introduction] This product is an alumino-silicate needle-punched blanket (ceramic fiber blanket), made of molten alum-silicate spun fibers, double-sided needle-punched and integrally formed without any chemical binders added throughout the process, odorless and no harmful substances released at high temperatures, with asbestos-free environmental standards. The three-dimensional interwoven fibers form a sealed air layer, providing excellent thermal insulation; it is available in 5 major common models covering the high-temperature working conditions from 800°C to 1400°C, with an additional aluminum foil composite version to enhance radiant insulation, moisture resistance, and corrosion.
【Five Core Advantages】 Ultra-high temperature resistance, non-combustible in open flames, Class A fireproof Standard withstand 800°C long-term, standard 1000°C, high purity 1260°C, and zirconium-containing 140°C; they do not burn or drip when exposed to open flames, making them specifically designed for fireproof wrapping of fire exhaust ducts and high-temperature equipment. Extreme insulation, significant energy saving Internal sealed air pores block heat conduction, with a thermal conductivity coefficient as low as 0.035W/(m・K) at room temperature, equipment heat dissipation and lowering energy consumption of boilers and kilns. Needle-punched reinforcement, high tensile strength without dusting Double-sided needle-punching process ensures strong interlacing, making it difficult to delaminate or shed debris when pulled, and resistant to pulverization and falling off during construction and long-term high-temperature use. Chem stable, acid and alkali resistant, anti-aging Stable in neutral/oxidizing environments, resistant to water vapor, weak acids, and weak alkalis; restores insulation performance after oil immersion and drying, and does not pulverize or rot during long-term use. Easy to process and install, flexible adaptation Soft texture allows arbitrary cutting with a utility knife, convenient-based laying, suitable for wrapping pipes, furnace bodies, and irregularly shaped equipment, ensuring high construction efficiency. 【Model Selection Guide】 Standard Type C (800°C Economical type, suitable for domestic ovens, low-temperature pipes, and small boilers, offering high cost-performance. Standard Type S (1000°C) industrial type, suitable for steam pipes, heat treatment furnaces, and exhaust ducts, the mainstream choice for construction sites. High Purity Type P (1260°C) power plants, high-temperature kilns, and heat treatment equipment, with low slag ball content and no shrinkage under long-term high temperatures. High Alumina Type A (150°C) Suitable for high-temperature industrial furnaces, forging furnaces, and heat treatment trolley furnaces. Zirconium-containing Type Zr (1400°) Suitable for ultra-high temperature equipment, metallurgical kilns, and special heat treatment, resistant to high-temperature creep. Aluminum Foil Composite Type Suitable for outdoor pipes humid environments, and exhaust ducts, reflecting heat radiation and providing moisture/water vapor protection. 【Applicable Industries and Equipment】 Thermal Power: Steam boilers, heat transmission pipes, power flues, turbine insulation Industrial Kilns: Heat treatment furnaces, forging furnaces, ceramic kilns, drying ovens, mold insulation Fire Ventilation: Fire exhaust duct fireproof wrapping, hightemperature exhaust pipes Chemical and Metallurgical: Reactor linings, casting slag protection, high-temperature reaction equipment insulation Civilian Equipment: Industrial ovens, exhaust pipes, high-temperature drying, fireplace linings
