Ceramic Fiber insulation is made from ceramic fiber or ceramics fiber, produced to specific standards with temperature ratings of 1,260°C, 1,400°C, or 1,430°C, and up to 1,600°C. The production process involves melting raw materials at high temperatures to create a liquid, which is then spun into fiber using two methods before being formed into various products.
Method 1: Blown Process This method uses air pressure to blow the liquid through a nozzle, forming the fibers.
Method 2: Spun Process This involves spinning at high speeds to create longer and stronger fibers compared to the blown method.
Ceramic Fiber insulation is renowned for its excellent thermal insulation properties, including low thermal conductivity, good resistance to rapid temperature changes, and high-temperature tolerance. This makes it suitable for high-temperature applications such as furnaces, kilns, and ovens. Ceramic Fiber insulation comes in various forms:
Ceramic Fiber Blanket This is a roll-type blanket available in thicknesses of 0.5 inches, 1 inch, and 2 inches. It is similar to a blanket, making it easy to install and suitable for applications like gaskets, seals, and wrapping around areas such as door edges, kiln lids, and to prevent heat expansion in kilns. It is used as a backup layer in various industrial high-temperature applications, including aluminum and steel melting furnaces, ceramic kilns, charcoal ovens, and pipe insulation. It can also be used to line the interior of ovens, like pizza or pastry ovens, to maintain internal temperatures.
Ceramic Fiber Board This insulation has a higher density compared to Ceramic Fiber Blanket and is available in board form. It is lightweight, with low shrinkage and thermal conductivity, resistant to high-temperature erosion, and effectively prevents liquid infiltration, such as aluminum. It is suitable for use as a backup layer in industrial heating systems, including melting furnaces, ovens, kilns, and coating processes.
Ceramic Fiber Paper This insulation is thin, resembling paper, with standard thicknesses of 1 mm, 2 mm, 3 mm, 5 mm, and 6 mm. It is ideal for use as a liner for heated workpieces, sealing gaps, and creating gaskets for flanges. It can also be used as high-temperature packaging and as a backup lining for metal melting furnaces, ovens, or kilns. Its thin, flexible nature makes it easy to install and it withstands high temperatures and abrasion well, with low thermal conductivity.
Ceramic Fiber Tape This insulation tape, made from ceramic fiber, is available in thicknesses of 2-3 mm, widths of 2 or 3 inches, and lengths of 30 meters. It may include internal stainless steel wire (SUS-304) for reinforcement and has a high density of up to 500 kg/m³. It is suitable for use as a high-temperature gasket for flange sealing, wrapping steam or hot air ducts, and can handle moderate to high temperatures (up to 1,260°C). It is commonly used in boiler industries and for applications involving heaters.
Ceramic Fiber Rope Also known as fire-resistant rope or high-temperature rope, this comes in two types: square-braided and round-braided. It can withstand temperatures up to 1,260°C and often contains internal stainless steel (SUS304) reinforcement. It is suitable for sealing oven doors, kilns, heat-resistant gaskets, exhaust pipe insulation for vehicles, boats, or machinery, and steam pipes. It helps seal areas where heat may escape from furnaces or other high-temperature applications.
