What Happens When Your Insulation Can’t Keep Up?
Cracking at the first thermal cycle. Compression set that ruins a gasket seal. Fibers that shed and contaminate your process. If you’ve dealt with these failures, you already know that not all high-temperature insulation is equal.
Ceramic Fiber Felt is the material you switch to when blanket is too soft, board is too rigid, and paper is too thin. It offers the flexibility to wrap complex shapes, the density to hold dimensional tolerances, and the purity to perform in sensitive environments—all in one product.
Our factory produces Ceramic Fiber Felt in three temperature grades and four density options. Every sheet is checked for thickness uniformity, tensile strength, and surface quality before it leaves our floor. No middlemen. No repackaged stock. Direct from our production line to your dock.
Three Things That Make Ceramic Fiber Felt Different
1. Density That Works, Not Just Fills Space
Most insulation products trade flexibility for strength. Ceramic Fiber Felt refuses that trade-off. At 200 to 400 kg/m³, it is dense enough to resist compression under load yet flexible enough to bend around curved surfaces without cracking. This makes it the preferred choice for die-cut gaskets that must maintain seal integrity under bolt pressure and thermal cycling.
2. Surface Quality That Protects Your Product
Loose fibers on an insulation surface can contaminate sensitive manufacturing processes. Ceramic Fiber Felt is wet-formed to create a smooth, uniform surface with minimal fiber release. For semiconductor fabs, food processing lines, or cleanroom equipment, this surface quality is not a luxury—it is a requirement.
3. Thermal Performance Without the Wait
Low heat storage means your furnace or kiln reaches operating temperature faster and cools down sooner. Ceramic Fiber Felt combines low thermal conductivity with low thermal mass, giving you shorter cycle times and lower energy bills. The numbers: as low as 0.06 W/m·K at 400°C. The result: measurable cost savings from the first month of operation.

Where Ceramic Fiber Felt Earns Its Keep
Furnace door gaskets. The felt compresses under clamping force, springs back after thermal cycles, and seals tight—cycle after cycle. Maintenance teams replace gaskets less often and lose less heat through door gaps.
Induction coil liners. Electrical insulation plus thermal protection in one layer. Ceramic Fiber Felt wraps around copper coils without breaking, protecting both the coil and the workpiece from heat damage.
Expansion joint packing. Refractory linings expand and contract. Ceramic Fiber Felt fills the gap, absorbs the movement, and prevents hot gas bypass. No cracking. No blowout.
Kiln car tops and setter plates. In ceramic and glass processing, a smooth, non-contaminating surface matters. Ceramic Fiber Felt supports the load while keeping the product clean and the heat where it belongs.
Automotive heat shields. Lightweight, flexible, and resistant to exhaust temperatures. Ceramic Fiber Felt is cut into formed shields that protect fuel lines, wiring harnesses, and electronic modules from radiant heat.
Foundry ladle covers. Molten metal splash is unforgiving. Ceramic Fiber Felt takes the hit, contains the heat, and keeps the ladle shell from warping.
We Machine It. You Install It.
Raw sheets are only half the story. Most of our B2B customers need Ceramic Fiber Felt in finished form:
-
Die-cut gaskets with bolt holes and tight tolerances
-
CNC-routed shapes from your CAD drawing
-
Adhesive-backed strips for fast peel-and-stick installation
-
Foil-faced panels for radiant heat reflection
-
Laminated blocks for extra thickness without extra lead time
Send us a drawing, a sketch, or even a photo of the part you’re replacing. We’ll quote it within 24 hours and ship finished pieces that drop straight into your assembly line.
What Buyers Ask Us Most
Q: How does Ceramic Fiber Felt compare to Ceramic Fiber Board?
Board gives you rigidity. Felt gives you flexibility plus similar density. If your surface is flat and you need structural support, choose board. If you need to wrap, bend, or die-cut a seal, Ceramic Fiber Felt is the better call.
Q: Does it shed fibers during handling?
Standard Ceramic Fiber Felt has minimal fiber release due to the wet-forming process. For cleanroom or food-grade applications, we offer surface-hardened or encapsulated grades that virtually eliminate dusting.
Q: Can it be used with molten aluminum?
Standard felt is not recommended for direct aluminum contact. Ask about our non-wetting grades specifically formulated for molten aluminum and zinc.
Q: What is your lead time?
Stock sizes ship within 3–5 working days. Custom-cut or custom-density Ceramic Fiber Felt takes 10–15 working days. Large-volume OEM programs qualify for scheduled releases and vendor-managed inventory.
Q: Do you provide samples?
Yes. Standard samples ship free to qualified B2B buyers. Custom samples may require a small tooling fee, credited back on your first bulk order.
One Supplier for Every Ceramic Fiber Need
We don’t just make Ceramic Fiber Felt. Our production range includes blanket, board, paper, and custom-machined parts. That means one quality system, one point of contact, and consistent material across every insulation layer in your operation.
Whether you’re prototyping a new furnace design or re-sourcing an existing gasket line, you’ll get a direct response from our engineering team—not a sales script.
