CERAMIC FIBRE PRODUCTS

SUNTHERM Ceramic Fiber Products — Your Reliable Solution for High-Temperature Insulation

Ceramic fiber is a new type of lightweight, high-temperature refractory material primarily made from high-purity alumina, silica, and other raw materials. It is produced by melting in an electric resistance furnace, fiberizing by centrifugal spinning, followed by needle punching and forming processes. It features excellent high-temperature resistance, low thermal conductivity, good thermal stability, and superior thermal shock resistance. Ceramic fiber products are widely used in metallurgy, building materials, power generation, petrochemical, ceramics, glass, and other high-temperature industries, serving as an ideal alternative to traditional refractory materials.

SUNTHERM focuses on the R&D and manufacturing of ceramic fiber materials, offering a complete product range to meet the insulation and energy-saving needs of various industrial furnaces and high-temperature equipment:

■ Ceramic Fiber Blanket
✅Made from spun ceramic fibers via double-sided needle punching, it has excellent tensile strength and flexibility. Suitable for furnace lining, backing insulation, flue gas ducts, heat treatment furnaces, electric furnaces, casting, and more. Available in standard, high purity, high alumina, and zirconia grades, with optional aluminum foil or non-woven facing.

■ Ceramic Fiber Board
✅Manufactured by vacuum forming or wet forming from ceramic fiber wool, it offers high strength, good erosion resistance, and dimensional stability. Mainly used for insulation and fire sealing of industrial furnace walls, doors, combustion chambers, kiln cars, and hot air ducts.

■ Ceramic Fiber Paper
✅Made from superfine ceramic fibers and a small amount of organic binder, it is uniform in thickness, flexible, and highly temperature resistant. Widely applied in electric heating element insulation, sealing gaskets, mold insulation, and electrical insulation, featuring low heat capacity, low thermal conductivity, and asbestos-free.

■ Ceramic Fiber Module
✅Produced by folding and compressing ceramic fiber blankets and fixed onto furnace structures with anchors. Quick installation and high integrity. Used in steel reheating furnaces, heat treatment furnaces, petrochemical cracking furnaces, and more, significantly improving furnace thermal efficiency and reducing construction time.

■ Vacuum Formed Ceramic Fiber Shapes
✅Custom-made according to client drawings or specifications, manufactured by vacuum forming ceramic fibers and binders. Features precise dimensions, tolerance control, and excellent strength. Widely used in complex thermal equipment structures, fireproof components, electric furnace sealing systems, gating cups, and nozzle protection.
