Ceramic Blanket Needled Ceramic Fiber Insulation
The lightweight lining that keeps the heat where you paid for it. Ceramic fiber blanket stores very little heat, so furnaces lined or backed with it heat up faster and lose less through their walls. It is flexible enough to wrap and pack, cuts with a knife, and takes thermal shock that would crack dense brick.
Chelora Chemicals is a ceramic blanket supplier and sourcing partner serving foundries and furnace users across the United States. We supply needled blanket in 4, 6 and 8 pcf densities and 2,300 °F and 2,600 °F grades, with a data sheet and SDS with every lot.

Choosing a blanket for the hot face
Grade follows temperature; density follows strength and conductivity.
Why it matters: dense refractory soaks up heat every time a furnace cycles. Fiber linings store far less, so intermittent furnaces save the most
What ceramic blanket is and does
Ceramic blanket is refractory ceramic fiber needled into a flexible mat, with no binder. Needling locks the fibers together for handling strength and tear resistance. Common densities are 4, 6 and 8 pcf, and common thicknesses are ½, 1 and 2 inches.
Grades are named by classification temperature: a standard 2,300 °F (1,260 °C) grade and a 2,600 °F (1,430 °C) high-temperature grade. Its value is low thermal conductivity and very low heat storage, so it insulates well and heats up fast, and its resistance to thermal shock. In foundries it lines and backs up furnaces, ladles and lids, and wraps hot equipment.
What to tell us when you order
- The hot-face temperature. Sets the grade, with headroom above it.
- The density. Higher density for strength and lower conductivity; lower for light back-up.
- The thickness and roll size. To suit the lining design.
- Related forms. Rope for seals, cloth for wraps.

Importing into the United States
Ceramic fiber blankets are manufactured articles, not bulk chemicals. Articles are generally outside the TSCA section 13 import certification requirement unless an EPA rule specifically requires it, and we confirm the position with your broker before the first shipment. Safety information is supplied to OSHA's Hazard Communication Standard where the producer issues an SDS.
Which party carries that duty follows the Incoterm. On FOB, CFR or CIF terms it is usually the US buyer; on DDP terms it can be the seller or its agent. Safety data sheets and labels are supplied to OSHA's updated Hazard Communication Standard, and the non-dangerous goods transport documentation is prepared before booking.
| Item | How it works |
|---|---|
| Delivery points | Any nominated US plant, terminal or port of discharge |
| Incoterms quoted | FOB · CFR · CIF · DDP |
| Importer of record | Agreed in writing before the first shipment |
| TSCA certification | Section 13 positive certification filed at entry |
| Documentation | Batch COA, SDS, packing list, certificate of origin |
| Pack formats | Rolls in cartons, palletized |
Note: regional coverage describes where we deliver, not where we hold inventory. Lead time depends on producer scheduling and ocean transit to your nominated US port — we confirm both in the quotation.
How we supply ceramic blanket
Chelora Chemicals is a ceramic blanket supplier and sourcing partner, not a manufacturer. We place your order with a qualified producer whose grade and density fit your lining.
We start with the hot-face temperature, and specify a grade with headroom. A blanket run close to its classification temperature shrinks and opens gaps; one rated above the duty does not.
We also state the fiber classification plainly, and quote low-biopersistence AES blanket where your temperature allows it, so you can choose with the full picture.
- Grade with headroom. 2,300 °F or 2,600 °F, matched to your hot face.
- Density to the duty. 4, 6 or 8 pcf.
- Thickness and roll size to order. To suit your lining design.
- Classification stated up front. RCF handling guidance with every lot.
- AES alternative quoted. Where the temperature allows.
- Batch traceability to the producing plant. Data sheet and SDS per lot.
Rolled and cartoned
Blanket in rolls, cartoned and protected from moisture, with full documentation.
Cartoned rolls or spools
Rolls and spools packed in cartons, the standard unit.
Moisture-protected
Shrink- or poly-wrapped against moisture in transit.
Strapped pallets
Cartons palletized for container shipment.
Short lengths or single rolls
Small quantities to prove fit and performance.
Incoterms to suit you

Ceramic fiber: handle with care
Ceramic blanket is made from refractory ceramic fiber, and cutting, fitting and especially removing it after service release fibers. Fibers irritate skin and eyes, and RCF carries a possible carcinogen classification by inhalation. After long service at high temperature, crystalline silica can form in the fiber. The summary below is orientation only; the producer's SDS is the authoritative document.
Classified hazards
FiberAirborne fibers: may cause cancer by inhalation (IARC Group 2B).SkinFibers cause temporary skin and eye irritation; wear gloves and eye protection.DustCutting and handling release fibers: use local extraction and respirators.SiO₂After-service material may contain crystalline silica.SDSFollow the producer's SDS for handling and removal.
What the US record says about refractory ceramic fiber. RCF (CAS 142844-00-6) is classified by IARC as Group 2B, possibly carcinogenic to humans, and producer SDSs carry the hazard statement "May cause cancer by inhalation." There is no specific OSHA PEL for RCF; the ACGIH TLV is 0.2 f/cc as an 8-hour TWA, and producers publish a recommended exposure guideline of 0.5 f/cc. After long service above about 1,100 °C (2,012 °F), crystalline silica may begin to form, which matters when old insulation is removed. Low-biopersistence AES fiber grades are available where their temperature limit suits the job.
Storage
Store indoors in a dry area, in original packaging until use, off the floor. Keep material dry: wet insulation loses performance and must be dried before it meets heat or molten metal.
Handling
Minimize airborne fibers: cut with knives or shears rather than power saws, work with local extraction, and clean up with a HEPA vacuum, never dry sweeping or compressed air. Wear gloves, long sleeves, eye protection and a respirator suited to the exposure, as the SDS directs. Take extra care when removing after-service material.
Transport
Ceramic fiber products ship as non-dangerous goods. Packaging protects them from moisture and crushing. We confirm packaging and documentation for your destination before booking.

We verify documentation before dispatch so there are no surprises at your incoming-goods bench.

The producing plant checks dimensions, density and construction on each lot before release.
Documentation review
Data sheet, SDS and quality certificate checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing lot, with full chain-of-custody records on request.
Why classification temperature is not the limit
Ceramic blanket grades are named by classification temperature — 2,300 °F, 2,600 °F — and it is easy to read that as the temperature the blanket can run at. It is not. Classification is a test-based rating, and producers give a lower continuous-use limit in the data sheet.
Run a blanket close to its classification temperature for long and it shrinks. In a lining, shrinkage opens gaps at the joints, and heat finds them. That is why linings are designed with a grade comfortably above the hot-face temperature, and why the 2,600 °F grade exists.
Long service at high temperature also changes the fiber itself: crystalline silica can begin to form at around 1,100 °C. That does not affect performance much, but it does affect how old insulation should be removed, which is worth planning before the tear-out.
We do not publish operating process parameters here; this is background only. Full technical documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
