Ceramic Fiber Packing
Ceramic fiber packing is braided from high-temperature ceramic fiber yarn and can be reinforced with fiberglass, stainless steel wire, or nickel wire to increase strength and abrasion resistance. It delivers outstanding heat resistance, chemical stability, and electrical insulation, making it ideal for sealing applications in demanding high-temperature and corrosive environments.We provide high-quality ceramic fiber packing, available in square braid and rope forms, designed for high-temperature sealing applications in demanding industrial environments.
Key Features
Exceptional High-Temperature Resistance
Withstands continuous operation up to 1260°C and short-term exposure to even higher temperatures, making it suitable for extreme industrial environments.
Excellent Flexibility and Mechanical Strength
The braided ceramic fiber structure retains elasticity and compressive resistance at high temperatures, accommodating dynamic sealing surface movements, vibrations, and deformation without cracking.
Very Low Thermal Conductivity and Heat Storage
Effectively blocks heat transfer, significantly reducing energy loss and improving equipment efficiency. Rapid heating and cooling make it ideal for intermittent high-temperature processes.
Superior Thermal Shock Resistance
Maintains structural integrity under rapid temperature fluctuations, preventing cracking or spalling, especially in applications with frequent thermal cycling.
Strong Chemical Corrosion Resistance
Resists most acids, alkalis, and organic solvents, suitable for sealing in chemically aggressive atmospheres such as chemical processing and metallurgy.
Lightweight and Easy to Install
Low weight, bendable, and easily cut to size, enabling quick on-site installation and replacement, reducing labor time and complexity.
Safe and Eco-Friendly
Asbestos-free and free of harmful volatile compounds, meeting modern industrial safety and environmental standards. Suitable for clean industries like food and pharmaceuticals.
Optional Lubrication Enhancement
Available with graphite impregnation to reduce friction coefficient, improving wear resistance and sealing longevity in dynamic applications.
