Ceramic FiberPacking : The Flexible Sealing Expert for Mastering Extreme Heat Beside high-temperature furnaces, valves, and pipelines in industries such as metallurgy, chemical, and power, temperatures often soar to several hundred or even over a thousand degrees Celsius. Here, traditional rubber or plastic sealing materials fail instantly, while metal gaskets struggle to cope with the expansion and vibration of complex working conditions. At this point, a white, soft, yet highly resilient material — ceramic fiber packing — becomes the critical component ensuring equipment safety, efficiency, and energy-saving operation. Ceramic fiber packing is a rope-like sealing filler primarily made from high-quality ceramic (aluminum silicate) fibers, processed through spinning and braiding. It inherits the exceptional properties of ceramic fibers: lightweight, high-temperature resistance, excellent thermal stability, low thermal conductivity, and good chemical corrosion resistance (exce...
