Ceramic Cloth 200 & 400 Grade High-Temperature Cloth
Insulation you can cut, sew and fold. Blanket and board are rigid or bulky; ceramic cloth is a woven fabric that drapes, wraps and seals. Foundries use it as a heat shield in front of a furnace door, a curtain across an opening, a gasket under a lid or a wrap around a pipe or tube that has to stay hot.
Chelora Chemicals is a ceramic cloth supplier and sourcing partner serving foundries and furnace users across the United States. We supply ceramic fiber cloth in 200 and 400 grades, with glass or wire reinforcement, and a data sheet and SDS with every lot.

Note: the reinforcement sets the working limit. The ceramic fiber outlasts glass filament; wire-reinforced cloth keeps its strength at higher temperatures. Confirm the grade for your duty.
From fiber to cloth
Ceramic fiber is spun into yarn with a carrier and reinforcement, then woven.
Why it matters: the organic carrier burns off on first heating. Expect some smoke and odor the first time cloth is brought up to temperature
What ceramic cloth is and does
Ceramic cloth is a woven fabric of refractory ceramic fiber yarn. Because ceramic fiber alone is too short and brittle to spin, it is spun with an organic carrier fiber and reinforced with glass filament or alloy wire. The carrier burns off on first heating; the reinforcement holds the weave together.
In a foundry it does the jobs rigid insulation cannot: heat shields and curtains across furnace openings, gaskets under lids and doors, wraps around pipes, tubes and thermocouple lines, and protective covers. We supply it in 200 and 400 grades; the weight, thickness and reinforcement of each grade are set out in the producer's data sheet.
Choosing a grade
- 200 and 400 grades. Confirm weight, thickness and weave from the data sheet for your duty.
- Reinforcement. Glass filament for general use; alloy wire where strength at temperature matters.
- Width and roll length. To suit how you cut and fit it.
- Related forms. Rope for seals, blanket for lining.

Importing into the United States
Ceramic cloths 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 cloth
Chelora Chemicals is a ceramic cloth supplier and sourcing partner, not a manufacturer. We place your order with a qualified producer whose grade fits your duty.
We ask what the cloth has to do: a curtain that hangs, a gasket that is compressed and a wrap that is flexed all stress the weave differently, and the reinforcement should follow the job.
We also make sure you know the fiber classification. Refractory ceramic fiber carries an IARC Group 2B classification, so cutting and handling practice matter, and lower-biopersistence alternatives exist for some duties.
- 200 and 400 grades. With the producer's data sheet for each.
- Reinforcement matched to the duty. Glass filament or alloy wire.
- Widths and lengths to order. To suit how you cut and fit.
- Classification stated up front. RCF handling guidance with every lot.
- Trial quantities before a contract. Prove it on your own equipment.
- Batch traceability to the producing plant. Data sheet and SDS per lot.
Rolled and cartoned
Cloth 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
Quoted on the Incoterm your purchasing team works to.
Scheduled deliveries
Annual volume released against your maintenance schedule.
Ceramic fiber: handle with care
Ceramic cloth is made from refractory ceramic fiber, and handling it releases fibers, particularly when it is cut, frayed or removed after service. Fibers irritate skin and eyes, and RCF carries a possible carcinogen classification by inhalation. 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.

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.

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 ceramic cloth smokes the first time
Ceramic fiber on its own is short and brittle, so it cannot be spun into yarn the way wool or cotton can. Producers solve this by blending it with an organic carrier fiber to spin, and adding glass filament or alloy wire for strength.
The first time the cloth is heated, the carrier burns out. That causes some smoke and odor, which is normal, and leaves a cloth of ceramic fiber held together by its reinforcement. Ventilate the area for that first heat-up.
It also explains why the reinforcement sets the working limit. The ceramic fiber survives far higher temperatures than glass filament does, so a glass-reinforced cloth loses strength before its fiber does. Where strength at high temperature matters, a wire-reinforced grade is the right choice.
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.
