Heat-Resistant Ceramic Fiber Textiles

Product Overview

Heat-resistant ceramic fiber textiles are high-performance flexible refractory materials produced using high-purity alumina and silica as primary raw materials. These materials are melted at high temperatures to form continuous fibers and then processed using specialized textile technologies.

This manufacturing process ensures fiber continuity and uniformity, allowing the product to combine the heat resistance of inorganic materials with the flexibility and workability of textiles. As a result, it is widely used for protection and sealing in extreme high-temperature environments.

Using high-purity alumina and silica as base materials, the product can withstand continuous operating temperatures up to 1260°C. Certain zirconia-containing grades can endure temperatures above 1400°C, with melting points exceeding 1760°C, while maintaining structural integrity even under direct flame exposure.

As a pure inorganic material, it does not burn, melt, or release toxic smoke when exposed to fire, effectively preventing flame spread and serving as a critical fire protection barrier in industrial and building applications.

The interwoven fiber structure forms a dense air layer, providing excellent thermal insulation performance. This significantly reduces equipment surface temperatures, minimizes heat loss, and improves working environments.

The use of continuous fiber technology combined with reinforcement using fiberglass or stainless steel wire greatly enhances tensile strength and wear resistance, enabling the material to withstand complex working conditions such as vibration and mechanical tension.

It also exhibits excellent chemical resistance, resisting most chemical media (except hydrofluoric acid and strong alkalis). The material does not age or degrade easily, ensuring long-term reliable performance.

Product Description

Heat-resistant ceramic fiber textiles are flexible refractory materials made from high-purity alumina and silica fibers, produced through high-temperature melting followed by specialized weaving processes. They combine the high-temperature resistance of ceramics with the flexibility and machinability of textiles, successfully overcoming the rigidity limitations of traditional refractory materials.

The ceramic fiber textile series typically includes cloth, tapes, ropes, and yarns, offering the following key advantages:

Excellent Temperature Resistance

Designed for long-term high-temperature operation, capable of handling extreme thermal conditions.

Superior Thermal Stability

Low heat capacity and low thermal conductivity provide outstanding resistance to thermal shock and enable the material to withstand severe heating and cooling cycles.

Flexible Mechanical Properties

Soft texture with high strength. The material can be easily cut, wrapped, sewn, or shaped, making it suitable for insulating complex equipment structures and pipelines.

Outstanding Chemical Stability

Resistant to acid and alkali corrosion and molten metal splashes, while maintaining stable performance in both oxidizing and reducing atmospheres.

Applications

Ceramic fiber textiles are ideal insulation, sealing, and protection materials for high-temperature industries, widely used in:

Furnace door sealing and thermal curtains in industrial kilns

Flexible insulation wrapping for high-temperature pipelines and valves

Thermal protection for welding and heat treatment equipment

Firefighting and emergency rescue safety protection equipment

FAQ

Q1: What is the main difference between ceramic fiber cloth and fiberglass cloth?
A1: The main differences lie in temperature resistance and chemical stability. Ceramic fiber cloth can withstand long-term operating temperatures of up to 1260°C and has strong resistance to acid and alkali corrosion, making it suitable for high-temperature or chemically corrosive environments. Fiberglass cloth typically has a heat resistance of around 250°C and is lower in cost, but it tends to become brittle after prolonged exposure to high temperatures.

Q2: Will use in humid environments affect product performance?
A2: The water absorption rate of standard ceramic fiber cloth is less than 5%. For high-humidity environments, we offer hydrophobic-coated versions (with water absorption controlled below 1%). It can also be used together with a moisture barrier or vapor barrier layer to ensure insulation performance and long-term stability.

Q3: Do you support customized composite structures? What are common composite options?
A3: Yes, various composite structures can be customized. Common options include:

Aluminum foil lamination: enhances heat reflection and improves insulation performance

Silicone coating: improves air tightness and flexibility, suitable for sealing and wrapping

Stainless steel wire reinforcement: significantly increases tensile strength, suitable for vibration or load-bearing environments

Q4: Will ceramic fiber cloth shrink or powder at high temperatures?
A4: High-quality ceramic fiber cloth undergoes high-temperature pre-treatment, and under normal operating conditions the shrinkage rate can be controlled within 3%. When exposed for long periods to extreme temperatures or severe thermal shock, slight surface powdering may occur. In such cases, it is recommended to select an appropriate product grade or apply additional surface protection.

Q5: What precautions should be taken during installation? Is a special adhesive required?
A5: During installation, avoid excessive stretching or tearing of the material. Overlapping areas should generally be 5–10 cm. If adhesives are used, only high-temperature-resistant adhesives (such as silicate-based or specialized ceramic adhesives) should be selected. Ordinary adhesives should not be used, as they may fail at high temperatures and cause fiber damage.
