Ceramic fiber materials, such as refractory ceramic fibers (RCF), are lightweight, high-temperature insulation materials widely used in furnaces, kilns, and other thermal equipment. Their excellent heat resistance, low thermal conductivity, and chemical stability make them ideal for industrial insulation and sealing applications.
At HENGRUI High Temperature Materials, we offer a complete range of refractory fiber products designed for various temperature grades and application requirements. Below are the 8 common forms of refractory ceramic fiber products.
1.Refractory Fiber Bulk
Refractory fiber bulk (also called ceramic fiber cotton) is a loose, fluffy material made from high-quality alumina-silica fibers. It serves as the raw material for producing blankets, boards, papers, and other formed products. It can also be used directly for filling, expansion joints, and irregular insulation areas.
2.Refractory Fiber Blanket
Ceramic fiber blanket is a soft, needled insulation product made without binders. It offers excellent flexibility, thermal shock resistance, and sound insulation, suitable for lining furnaces, kilns, and ducts.
👉 Available in various grades: 1,260°C, 1,430°C, and 1,500°C (zirconia content).
3.Refractory Fiber Felt
Ceramic fiber felt is similar to a blanket but contains a controlled amount of organic or inorganic binders, giving it added flexibility and structural strength. It’s ideal for insulating curved surfaces, pipelines, and expansion joints.
4.Refractory Fiber Module
Ceramic fiber modules are pre-assembled blocks made from folded or stacked ceramic fiber blankets. Designed for industrial furnace linings, they ensure fast installation, minimal heat loss, and easy maintenance.
They are commonly used in heat treatment furnaces, steel plants, and ceramic kilns.
5.Refractory Fiber Board
Ceramic fiber boards are rigid, flat insulation panels produced using a wet forming process and binders. They feature excellent compressive strength, low shrinkage, and smooth surface finish, making them suitable for furnace walls, roofs, and combustion chambers.
6.Refractory Fiber Shaped Products
Custom-shaped ceramic fiber parts (also called vacuum-formed shapes) are designed to meet specific application needs. They are produced by forming ceramic fiber slurry with organic or inorganic binders into complex shapes such as burner blocks, sleeves, and furnace components.
7.Refractory Fiber Paper
Ceramic fiber paper is a flexible, lightweight insulation material made using the papermaking process. It provides excellent dielectric strength, smooth surface, and thermal insulation, ideal for electrical insulation, gaskets, and seals in high-temperature environments.
8.Refractory Fiber Textiles
Ceramic fiber textiles include cloth, tape, and rope woven from ceramic fiber yarns. They are reinforced with glass fiber or stainless steel wire for enhanced tensile strength. These textiles are used in fireproof curtains, seals, and expansion joints.
