Description
Custom Flame Retardant Polyurethane Wheels for Fire Escape Carts – Self-Extinguishing PU Wheels from a Top China OEM/ODM Manufacturer
Why choose this flame retardant polyurethane wheel?
Fire escape carts sit in stairwells, corridors, and storage rooms where safety codes are strict and a failed component is unacceptable. The most common problems buyers report with ordinary wheels are three: they ignite or drip under heat, they flatten and lose their round shape after long static loads, and batch quality varies so much that inspection becomes a headache. Our flame retardant polyurethane wheels are designed around those exact pain points.
The flame retardant PU tread uses additives that trigger self-extinguishing behaviour, so the wheel does not sustain combustion or spread fire along the cart. Because the compound also retains tensile strength above 35 MPa and abrasion resistance comparable to standard industrial PU, you do not sacrifice durability to gain fire safety. The steel or aluminium core is machined to tight tolerances and dynamically balanced, which keeps rolling smooth and reduces vibration that could loosen cart fittings over time. Test reports covering flame retardancy, hardness, and abrasion resistance are available for each batch, giving you documented proof for audits and customer approvals.
Typical applications: Fire escape carts, emergency trolleys, hospital evacuation carts, safety equipment platforms, industrial carts, and any wheeled life-safety unit that must stay operational under heat exposure.

Material Properties of Flame Retardant PU
| Property | Test Method | Typical Value |
|---|---|---|
| Tensile strength | ASTM D412 | ≥35 MPa |
| Tear strength | ASTM D624 | ≥60 kN/m |
| Abrasion resistance | DIN 53516 | ≤50 mm³ |

| Compression set | ASTM D395 | ≤25% |
| Rebound resilience | ASTM D2632 | ≥45% |
| Hardness tolerance | Shore A | ±3 degrees |
Flame retardant additives can affect flexibility and rebound, so the compound is balanced to keep rolling performance close to standard PU while meeting fire safety expectations. If your fire escape cart carries heavy rescue gear and also needs low rolling resistance, tell us the load and floor type — we will suggest a hardness and core combination that fits both requirements. Custom hardness from Shore 80A to 95A and special compounds are available from our factory.
About Us – China OEM/ODM Manufacturer of Flame Retardant PU Wheels
Customers Visiting
Based in China, our factory has specialised in polyurethane wheels and rollers for more than a decade. Most of our output is custom engineered rather than pulled from a catalogue, which means material engineers, mould technicians, and quality inspectors work directly with production on the same floor. Over the years we have supplied fire safety equipment builders, warehouse automation integrators, cart manufacturers, and wholesale distributors across Europe, North America, and Southeast Asia. If you need a professional manufacturing partner who understands both PU engineering and export requirements, we are ready to work with your drawings, samples, or target specifications.

Production & Inventory Policy
Lead time: Actual lead time is affected by raw material supply, machine scheduling, and peak-season workload, so there will be reasonable fluctuation. We provide the most accurate delivery estimate possible after order confirmation and keep you informed throughout production.
Stock status: We generally do not hold finished stock, though a small number of fast-moving regular sizes may be available. Actual stock quantity changes dynamically with sales and production, so please contact our team to confirm current availability before placing an order.
Bulk & urgent orders: For large-volume orders or urgent fire safety projects, please contact us early so we can review capacity and scheduling. We will do our best to align with your timeline.
Frequently Asked Questions – Flame Retardant Polyurethane Wheels
1. What makes your flame retardant polyurethane different from standard PU?
Standard polyurethane can burn and produce dense smoke when exposed to fire, which is a serious problem on fire escape carts. Our flame retardant compound uses additives that trigger self-extinguishing behaviour, and the formula is tested to UL94 V-0 grade in our lab. It keeps mechanical properties close to conventional PU — tensile strength above 35 MPa, good abrasion resistance — so you do not have to trade durability for fire safety. Test reports are available for each batch on request.
2. Can you customize the diameter, hardness, and hub for our fire escape cart design?
Yes. As a custom solution provider in China, we produce wheels from 50 mm to 300 mm in diameter, with hardness from Shore A 80 to 95, and cores in steel, aluminium, or engineering plastic. Send us a drawing or sample, and our engineers will suggest the best combination for your cart load and rolling conditions. Custom colours and branding are also available for OEM/ODM projects.
3. What load capacity can these wheels handle?
Single wheel load capacity typically ranges from 50 kg to 800 kg, depending on diameter, hardness, and bearing type. For fire escape carts carrying heavy rescue equipment, we usually recommend a steel core with ball bearings and a diameter above 150 mm. Each batch is tested under dynamic load to confirm the rated capacity before shipment.
4. Do you provide flame retardant test reports?
Yes. We can supply material test reports covering flame classification, hardness, and abrasion resistance for each production batch. If you need third-party testing or a specific standard, tell us before ordering so we can schedule the test in advance. We recommend keeping these reports with your product compliance files, since fire safety buyers often request them during audits.
5. What is your MOQ, and do you support wholesale orders?
Our standard MOQ for custom flame retardant polyurethane wheels is 100 pieces per size. For wholesale distributors and OEM/ODM buyers, we can discuss flexible quantities, and mixed sizes in one order are usually acceptable. The more clearly you define your annual volume, the better we can advise on price and production planning.
6. How long is the lead time?
Lead time depends on size, quantity, and whether new tooling is needed. For regular sizes and small batches, we usually ship within 15 to 25 days after order confirmation. New moulds may add 10 to 15 days. We will give you an estimated schedule after reviewing your order and update you during production if anything changes.
7. What payment and shipping methods do you accept?
We accept T/T, L/C at sight, and other terms for regular buyers. Shipping can be arranged by sea, air, or express depending on your destination and urgency. For time-sensitive fire safety projects, we can coordinate air freight to shorten transit time. Let us know your preferred terms and we will confirm what works best for both sides.
8. Can I get a sample before placing a bulk order?
Yes. Samples are available for evaluation, and the sample cost is usually refundable against your first bulk order. We recommend testing the sample on your actual fire escape cart before confirming the full order, because real-world rolling conditions often reveal details that a specification sheet cannot. Our team is happy to advise on what to check during the trial.
9. What packaging and shipping options do you provide for international orders?
Standard packaging includes individual plastic bags and sturdy cartons. For bulk orders, we offer wooden cases, pallets, or full container loading. Anti-rust treatment is applied for sea freight. Wheels can be shipped by express, air, or sea depending on destination and urgency.
10. What warranty do you offer on flame retardant PU wheels?
Standard warranty is 180 days from shipment date against manufacturing defects. Extended warranty (12 months) is available for bulk orders. Normal wear and tear or improper installation is not covered. Please inspect the goods on arrival and raise any issue within the warranty window.
