Ceramic fiber is a lightweight, fiber-based energy-saving material that combines the advantages of traditional thermal insulation and refractory materials. It is non-combustible, resistant to high temperatures, thermally stable, lightweight, highly energy efficient, non-toxic, and odor-free. Initially used mainly in industrial furnaces and heat-treatment equipment, ceramic fiber materials have gradually been adopted across a wide range of industries, including machinery, metallurgy, chemicals, petroleum, transportation, shipbuilding, electronics, defense, aerospace, and nuclear energy.
In smoke and exhaust duct systems, ceramic fiber products are widely used as flange sealing gaskets due to their excellent compression recovery, heat resistance, and non-combustibility. Common ceramic fiber sealing materials include ceramic fiber ropes and ceramic fiber paper.
Ceramic Fiber Rope
Ceramic fiber rope is braided from high-quality ceramic fiber yarns and offers excellent thermal insulation performance. It is an ideal replacement for asbestos rope and is commonly used for wrapping high-temperature cables and pipelines.
Ceramic Fiber Paper
Ceramic fiber paper is produced from blown ceramic fiber bulk through processes such as washing, binder addition, and vacuum forming. It features high strength, good flexibility, and easy cutting, making it suitable for high-temperature gaskets, sealing, thermal insulation, and electrical insulation applications.
Key Advantages of Ceramic Fiber Gaskets
Excellent high-temperature resistance: Suitable for continuous service at 1260 °C, with short-term temperature resistance up to 1430 °C.
Strong chemical stability: Good resistance to acid and alkali corrosion, and capable of withstanding attack from molten metals such as aluminum and zinc.
Combined mechanical strength and insulation performance: Maintains good mechanical strength at high temperatures while providing excellent thermal insulation.
Outstanding electrical insulation: Offers better electrical insulation performance than glass fiber at both ambient and elevated temperatures.
Safe and environmentally friendly: Non-toxic, harmless, odor-free, and compliant with modern industrial safety and environmental requirements.
With these advantages, ceramic fiber fireproof gaskets provide reliable, safe, and efficient sealing solutions for smoke exhaust and fire protection systems.
