High-Temperature Ceramic Fiber Paper for Industrial Insulation
Ceramic fiber paper, also known as ceramic fiber sheet or alumina-silicate fiber paper, is a lightweight, high-temperature-resistant insulating material. Made from spun or blown ceramic fibers (primarily alumina-silicate), it combines exceptional thermal stability with mechanical flexibility.
Key Features:
Ultra-High Temperature Resistance: Withstands continuous use at 1260°C (2300°F) and short-term exposure up to 1400°C (2552°F).
Low Thermal Conductivity: Typically 0.12 W/m·K at 800°C, minimizing heat transfer.
Chemical & Corrosion Resistance: Inert to acids, alkalis, and most industrial chemicals (except hydrofluoric acid and strong alkalis).
Non-Combustible & Asbestos-Free: Complies with fire safety standards (e.g., ASTM E136) for zero flammability.
Flexible & Customizable: Available in thicknesses of 0.5–13 mm, widths of 610/1220 mm, and lengths up to 120 m. Can be cut, molded, or laminated.
Types & Applications:
Standard Grade: For general insulation (600–1260°C) in furnaces, kilns, and piping.
High-Alumina Grade: Enhanced purity for semiconductor manufacturing and high-purity environments.
Zirconia-Containing Grade: For extreme temperatures (up to 1400°C) in aerospace and molten metal handling.
Common Uses: Gaskets, seals, expansion joints, fire barriers, electrical insulation, and acoustic damping
