The Ultimate Buyer’s Guide: How to Purchase Ceramic Fiber Paper
Are you in the market for Ceramic Fiber Paper ? Look no further.
This all-inclusive buyer’s guide provides you with crucial insights into Ceramic Fiber Paper, which find applications in metallurgical industry, power industry, ceramic industry, chemical industry and other heat treatment high temperature industries. Whether you’re contemplating importing them for your projects or planning local distribution, this guide furnishes invaluable information to guide your decision-making process.
Chapter 1
What is Ceramic Fiber Paper?
Your Go-To High-Temp Insulation Solution：
Ceramic Fiber Paper is a versatile, lightweight insulation material crafted from premium alumina-silica fibers, bonded into a dense, flexible sheet ideal for high-temperature applications. Manufactured through wet-lay or air-lay processes, this refractory paper combines exceptional heat resistance with mechanical durability, withstanding continuous temperatures up to 1260°C (2300°F) and short-term spikes exceeding 1400°C.
Thinner than traditional ceramic fiber boards yet stronger than standard insulation papers, it features a smooth surface and uniform density (typically 150–400 kg/m³), making it perfect for sealing, gasketing, and lining in tight or complex spaces. Unlike metallic or organic materials that degrade in heat, ceramic fiber paper maintains dimensional stability and insulation performance, making it a critical component in industries ranging from steel manufacturing to electronics.

Features of Ceramic Fiber Paper
Unlock the Advantages That Make Ceramic Fiber Paper a Top Insulation Choice：
- High-Temperature Resistance
Performs continuously up to 1260°C and resists short bursts up to 1400°C—ideal for furnace doors, kiln seals, and thermal barriers. - Excellent Insulation
With ultra-low thermal conductivity (0.11 W/m·K at 500°C), it cuts heat loss and boosts energy efficiency in industrial ovens and boilers. - Flexible & Easy to Shape
Available in 0.5–6 mm thickness; easy to cut or punch into gaskets or custom parts—perfect for complex sealing needs. - Strong & Durable
Tough fiber structure resists tearing and punctures, even in high-vibration or thermal cycling conditions. - Chemical Resistance
Withstands acids, alkalis, and molten metals—reliable for harsh environments in petrochemical and incineration processes. - Fast Thermal Response
Low thermal mass allows quick heating/cooling—suitable for heat treatment, aerospace, and precision thermal control.
