TPU Coated Fabric for Life Rafts and Life Jacket Bladders
DERFLEX supplies airtight, waterproof and weldable TPU coated fabric for manufacturers of life raft tubes, inflatable life jacket bladders, marine rescue floats and OEM inflatable safety equipment.
Instead of selling one general fabric for all safety products, DERFLEX helps buyers match base textile, TPU coating side, thickness, softness, welding method and testing direction to the real bladder or raft structure.
Air-Holding Direction
TPU coating can be specified for airtight bladder construction when seam design and welding parameters are properly verified.
Weldable Surface
Suitable material directions can support high-frequency welding, hot-air welding, heat sealing or ultrasonic welding trials.
Foldable Strength
Reinforced nylon or polyester base fabric helps balance folding flexibility, tear resistance and dimensional stability.
OEM Roll Supply
Color, width, texture, coating side, roll length and packing can be discussed for repeated marine safety equipment programs.
What Is TPU Coated Fabric for Inflatable Marine Safety Products?
TPU coated fabric is a technical textile made by bonding thermoplastic polyurethane to a woven nylon or polyester reinforcement. For life rafts and inflatable life jacket bladders, the fabric must do more than resist water. It must support air retention, controlled welding, compact folding, handling strength and repeated inspection during production.
In this application, the correct material is usually selected around the finished product design: bladder size, inflation pressure, CO2 inflation system, valve area, folded package size, welding route, service condition and required market approval. DERFLEX supplies roll material for manufacturers and fabricators, then supports sample selection for testing before bulk production.
- TPU coated nylon for lightweight, flexible and high tear-strength bladder programs.
- TPU coated polyester for dimensional stability and selected raft or industrial inflatable structures.
- Double-side TPU coating for demanding airtight and cleanable bladder constructions.
- Custom surface finish to match welding, handling, anti-blocking and packaging needs.
Buyer Note for Safety Equipment Manufacturers
A coated fabric can be suitable for sample development, but final life raft or life jacket compliance depends on the complete product design, production process and third-party or authority approval route required in your market.
- Confirm the target product: life jacket bladder, raft tube, canopy part, floor part or rescue float.
- Send welding method, pressure requirement, valve design and drawing if available.
- Test airtightness, weld strength, peel strength, folding behavior and aging conditions before bulk order.
- Do not select only by GSM; base fabric, TPU formula and seam performance are equally important.

Custom TPU Bladder Fabric Structure for Your Product
The following table is a practical selection guide. Final values should be confirmed after sample testing, welding trials and finished product validation.
| Selection Item | Common Direction | Why It Matters for Life Rafts & Life Jacket Bladders |
|---|---|---|
| Base Textile | Nylon or polyester woven fabric; project directions may include 210D, 420D, 840D, 1000D or custom reinforcement. | Nylon is often selected for flexibility and tear strength; polyester can support dimensional stability and selected raft structures. |
| Coating Type | Polyether TPU or polyester TPU; single-side or double-side coating. | Marine inflatable products often require attention to hydrolysis resistance, air retention, flexibility and bonding strength. |
| Weight & Thickness | Lightweight to medium/heavy-duty constructions; target GSM and thickness selected by product size and pressure. | Life jacket bladders usually need compact folding; raft tubes often need stronger handling and seam performance. |
| Surface Finish | Matte, glossy, embossed, smooth, anti-blocking or customized finish. | Surface finish affects welding stability, folding, packing, appearance and handling during production. |
| Processing Compatibility | HF/RF welding, hot-air welding, heat sealing, ultrasonic welding or combined fabrication. | Weld strength and leakage control depend on coating structure, machine setting and seam design. |
| Testing Focus | Airtightness, hydrostatic pressure, weld strength, peel strength, low-temperature folding, aging and saltwater exposure. | Safety equipment factories should validate fabric behavior under the final application and target compliance path. |
| Supply Format | Roll goods with custom width, color, roll length, core, packing label and batch information. | Repeatable roll supply helps OEM factories keep production, cutting and inspection more consistent. |

How to Request a More Accurate Quote
Marine safety applications need clearer information than ordinary waterproof fabric inquiries. Providing the following details helps DERFLEX recommend a more practical sample direction.
- Finished product: life jacket bladder, life raft tube, rescue float or other inflatable safety product.
- Target fabric: TPU coated nylon, TPU coated polyester, single-side or double-side coating.
- Expected GSM, thickness, color, width, roll length and surface finish.
- Welding method: HF/RF welding, hot-air welding, heat sealing or ultrasonic welding.
- Air pressure, leakage requirement, valve type, folding package and operating temperature range.
- Sample quantity, bulk quantity, destination port and required documents.
Do Not Choose Bladder Fabric by Price or Thickness Alone
A thicker coated fabric may still fail if it is too stiff for folding, weak at welded seams, unstable during valve bonding, unsuitable for low-temperature packing or not aligned with your inspection method. For inflatable safety products, the material should be judged together with fabric base, coating formula, adhesion, seam route and finished product test plan.
DERFLEX can help compare TPU coated nylon and TPU coated polyester directions, then prepare samples for your welding and airtightness verification. This is especially useful for life jacket factories, life raft manufacturers, marine rescue equipment brands and contract fabricators that need repeatable material supply.
TPU, PVC and PU-Coated Fabric: Which Direction Should You Test?
Different inflatable marine products require different balances of cost, folding, welding, strength and aging performance.
TPU Coated Fabric
Often considered for flexible, airtight, weldable and foldable bladder structures where a clean surface and low-temperature flexibility are important.
PVC Coated Fabric
Can be practical for cost-sensitive inflatable or waterproof products, but final use should be checked against weight, flexibility and compliance needs.
PU-Coated Fabric
Used in some marine inflatable safety products and life raft constructions; selection depends on product standard, supplier process and test data.
