Ceramic fiber (alumino-silicate fiber) is a high-temperature insulation material widely used for refractory linings, furnace blankets, and industrial thermal protection. It offers low thermal conductivity, excellent thermal shock resistance, and superior stability at elevated temperatures.
Ceramic Fiber Insulation, also known as Alumino-Silicate Fiber, is a high-temperature refractory material engineered for superior thermal performance and energy efficiency. It’s designed to withstand extreme heat — up to 1260°C — while maintaining low thermal conductivity, excellent thermal shock resistance, and exceptional chemical stability.
Manufactured by melting alumina and silica at high temperatures and then spinning or blowing the molten material into fibers, ceramic fiber products are lightweight, flexible, and durable. They are commonly supplied as blankets, boards, modules, papers, and bulk fibers — ideal for high-temperature insulation across industrial and commercial sectors.
Ceramic fiber insulation is composed primarily of silica (SiO₂) and alumina (Al₂O₃), with minor additives to enhance flexibility and resistance to chemical attack. The manufacturing process produces long, interlocking fibers that create a porous yet stable structure. This allows the material to retain strength and insulation capability even at elevated temperatures.
Common grades include 1260°C (STD), 1360°C (HZ), and 1430°C (HAZ) fibers for continuous exposure in furnaces, kilns, ducting, expansion joints, and boiler linings.
The fibers are available in multiple forms — including Blankets, Boards, Modules, Ropes, and Bulk Fiber — to suit specific installation and insulation needs.
