Product Overview
Ceramic Fiber Paper is a lightweight, flexible insulation material manufactured from high-purity alumina-silicate fibers. It is engineered for applications that require excellent thermal insulation, low heat storage, and resistance to thermal shock in a thin, easy-to-handle format. Unlike rigid boards or bulky blankets, Ceramic Fiber Paper offers the unique advantage of being cut, wrapped, or die-punched into precise shapes, making it ideal for gaskets, expansion joints, and fine thermal barriers.
Our Ceramic Fiber Paper is produced through a specialized wet-forming process that ensures uniform fiber distribution, smooth surface finish, and consistent thickness across the entire roll. It contains no asbestos and no hazardous binders, offering a clean and safe solution for high-temperature sealing and insulation. With continuous operating temperatures up to 1260°C, this product delivers reliable performance in demanding industrial environments.
Key Features
-
Low Thermal Conductivity
The Ceramic Fiber Paper provides excellent insulation performance, with thermal conductivity as low as 0.06 W/m·K at 400°C. It minimizes heat transfer while maintaining a thin profile, making it especially useful where space is limited. -
High-Temperature Resistance
Designed for continuous service up to 1260°C, the Ceramic Fiber Paper retains its flexibility and structural integrity even after prolonged exposure to extreme heat. It resists degradation and does not become brittle. -
Superior Thermal Shock Resistance
Ceramic Fiber Paper Rapid temperature changes can crack rigid insulation, but Ceramic Fiber Paper absorbs thermal stress without spalling or fracturing. This characteristic makes it ideal for intermittent heating cycles and emergency access seals.
-
Lightweight and Flexible
Weighing significantly less than refractory board or castable, Ceramic Fiber Paper can be cut with scissors or a knife, wrapped around curved surfaces, and installed in areas that are difficult to reach. It conforms easily to complex geometries. -
Excellent Chemical Stability
The Ceramic Fiber Paper resists attack from most acids, alkalis, and organic solvents. It does not outgas or release contaminants, ensuring clean operation in sensitive applications such as food processing and medical equipment. -
Uniform Thickness and Smooth Surface
Each roll of Ceramic Fiber Paper is manufactured to precise thickness tolerances, providing a consistent surface for gasket seating and sealing applications. The smooth finish also improves handling and reduces fiber dusting. -
Asbestos-Free and Safe
Our Ceramic Fiber Paper contains no asbestos or other hazardous materials, complying with international health and safety regulations.

Applications
Ceramic Fiber Paper is used across diverse industries where thin-profile, high-temperature insulation and sealing are required:
-
Gaskets and Seals
Die-cut Ceramic Fiber Paper gaskets provide excellent sealing for furnace doors, flue connections, and high-temperature piping systems. The material remains flexible and resilient under compression, maintaining a tight seal over repeated thermal cycles. -
Expansion Joint Filler
In high-temperature ductwork and refractory linings, Ceramic Fiber Paper serves as a compressible filler that absorbs thermal expansion without cracking or losing its insulating properties. -
Backup Insulation
The Ceramic Fiber Paper is frequently used behind dense refractory castables or bricks to reduce heat loss and prevent cracking caused by thermal gradients. -
Electric and Induction Furnaces
As a lining separator or coil wrap, Ceramic Fiber Paper provides electrical insulation and thermal protection in induction heating systems and electric kilns. -
Automotive and Aerospace
Heat shields, exhaust gaskets, and thermal barriers in high-performance vehicles and aircraft use Ceramic Fiber Paper to protect sensitive components from extreme heat. -
Appliance and Fire Protection
Ovens, stoves, and fire doors incorporate Ceramic Fiber Paper as a lightweight insulating layer that meets fire safety standards. -
Molten Metal Handling
Special non-wetting grades of Ceramic Fiber Paper are available for use as a parting layer or liner in molten aluminum transfer systems.
Custom Processing and Die-Cutting
We understand that many B2B customers require Ceramic Fiber Paper in finished part form rather than raw rolls. Our in-house converting capabilities include:
-
Die-cutting — precision-cut gaskets, washers, and complex shapes to your drawing
-
Slitting — narrow width rolls for automated production lines
-
Adhesive backing — pressure-sensitive adhesive applied to one side for easy installation
-
Lamination — bonding multiple layers for increased thickness or density
-
Foil facing — aluminum foil or stainless steel mesh laminated for added strength and reflectivity
To request custom-processed Ceramic Fiber Paper, please provide your drawing, required dimensions, and estimated annual usage. We will respond with a quote within 24 hours.
Packaging and Shipping
Each roll of Ceramic Fiber Paper is carefully protected for safe delivery:
-
Rolled on a sturdy core and wrapped in moisture-proof film
-
Placed in heavy-duty cardboard boxes or export cartons
-
Die-cut parts are packed with foam dividers to prevent edge damage
-
Palletized and shrink-wrapped for container loading
-
Full documentation including packing list, CO, and material certificates
We ship worldwide by sea, air, or express courier. Standard thicknesses are maintained in stock for rapid dispatch. Custom-thickness Ceramic Fiber Paper typically requires 10–15 working days for production.
Frequently Asked Questions
Q: What thickness of Ceramic Fiber Paper should I choose for gasket applications?
A: For most gasket applications, we recommend 1 mm to 3 mm thickness. Thicker Ceramic Fiber Paper (5–6 mm) is suitable for expansion joints and applications requiring greater compressibility. Our technical team can recommend the optimal thickness based on your specific operating conditions.
Q: Can Ceramic Fiber Paper be used in direct contact with flames?
A: Yes, Ceramic Fiber Paper can withstand direct flame impingement up to its rated temperature. However, for continuous flame exposure, a thicker grade or a rigid board may be more suitable depending on the application.
Q: Does Ceramic Fiber Paper contain binders that will burn off?
A: The Ceramic Fiber Paper contains a small amount of organic binder to provide handling strength in the green state. This binder burns off during the first heat-up without affecting the insulation performance or causing harmful emissions.
Q: Is Ceramic Fiber Paper resistant to oil and water?
A: The Ceramic Fiber Paper is naturally resistant to oil and organic solvents. It can absorb water if directly exposed, so it should be stored in a dry environment. For applications requiring water resistance, we offer hydrophobic-treated grades.
Q: Can Ceramic Fiber Paper replace ceramic fiber blanket?
A: In many thin-profile applications, yes. Ceramic Fiber Paper offers a smoother surface and more uniform thickness than blanket, making it preferable for gaskets and precision insulation. For thick insulation layers, blanket remains the more economical choice.
Q: Do you provide samples for evaluation?
A: Yes, we offer free standard samples of Ceramic Fiber Paper to qualified B2B buyers. Custom grades or die-cut samples may require a setup fee, refundable on the first production order.
