What is TPU fabric for inflatable products?
TPU fabric for inflatable products is a technical composite textile made by coating or laminating thermoplastic polyurethane onto a woven base fabric such as nylon or polyester. The textile layer gives tensile strength, tear resistance and dimensional control, while the TPU layer creates waterproof, airtight and weldable performance.
For inflatable products, the material is usually selected by air-holding requirement, seam welding method, target pressure, foldability, abrasion exposure, surface finish and finished product size. DERFLEX helps buyers match the fabric construction to the product instead of using one generic roll for every application.
Built for Products That Must Hold Air
Inflatable products fail most often at the material, seam or specification stage. A suitable TPU coated fabric should support stable welding, controlled coating thickness, clean surface quality and consistent roll-to-roll performance.
- Air chambers and pressure-support structures
- Marine and outdoor products exposed to folding and friction
- Medical or safety products requiring cleanable surfaces
- OEM programs needing repeatable bulk rolls
Why manufacturers choose TPU coated fabric for inflatables
TPU is valued when finished products need a combination of air retention, flexibility, welding compatibility and surface durability.
Airtight Structure
TPU coating can be engineered for air-holding products such as air mattresses, bladders, packrafts, inflatable tubes and sealed chambers.
Weldable Seams
The material can be processed by HF welding, hot-air welding, heat sealing or ultrasonic welding depending on coating structure and product design.
Flexible Folding
TPU coated nylon is often selected for foldable inflatables where soft handling, repeated packing and low-temperature flexibility matter.
Abrasion Resistance
Surface finish and fabric denier can be adjusted for products exposed to dragging, loading, marine use, field use or outdoor handling.
Clean Appearance
Glossy, matte, embossed and textured finishes can support brand design, anti-slip requirements, cleaning needs or customer-specific appearance.
OEM Customization
DERFLEX can customize fabric base, coating side, weight, thickness, width, color, hardness, roll length and packaging for project orders.

How to specify TPU fabric for inflatable products
The final specification should be confirmed by sample welding, air retention test and end-use performance evaluation.
| Base Fabric | Nylon or polyester. Nylon is often selected for flexible, foldable and high-tear applications; polyester is often selected for dimensional stability and cost-balanced industrial products. |
|---|---|
| Common Denier | 70D, 210D, 420D, 600D, 840D, 1000D, 1680D and customized structures depending on weight, pressure and finished product size. |
| Coating Side | Single-side TPU for lightweight waterproof goods; double-side TPU for air-holding inflatables, liquid containment and applications requiring better sealing reliability. |
| Weight Range | Approx. 90–1500 gsm depending on fabric construction, coating thickness and performance target. |
| Thickness | Approx. 0.05–1.2 mm or customized. Coating thickness affects welding strength, stiffness, air retention and cost. |
| Roll Width | Common 1.4 m–3.2 m with custom width options. Wider rolls can help reduce seams for large inflatable products. |
| Surface Finish | Matte, glossy, embossed, textile texture, anti-slip feel or customer-specific finish for brand and application needs. |
| Processing | HF welding, hot-air welding, heat sealing and ultrasonic welding. The welding method should be tested before mass production. |
| Custom Options | Color, hardness, coating side, coating thickness, anti-UV formulation, anti-bacterial option, roll length, label and packaging. |
Note: Values are general selection references. Final parameters should be confirmed according to pressure, product size, welding equipment, working environment and target market requirements.
TPU coated nylon, TPU coated polyester or drop-stitch compatible fabric?
Inflatable products are not all the same. Material selection should start from the function of the finished product.
TPU Coated Nylon
- Good option for flexible, compact and foldable inflatables
- Often used in packrafts, rescue gear, air bladders and outdoor products
- Selected when hand feel, tear strength and repeated packing are important
- Can be developed with single-side or double-side TPU coating
TPU Coated Polyester
- Practical option for dimensional stability and wider industrial use
- Often used in air structures, support chambers and heavier-duty products
- Suitable for bulk roll supply where stability and cost control matter
- Can be customized for color, thickness, finish and welding performance
TPU fabric vs PVC fabric vs PU fabric for inflatable products
Each material has suitable use cases. DERFLEX manufactures different coated materials and can help buyers select based on performance, processing and cost target.
| Material | Main Strength | Typical Inflatable Use | When to Choose |
|---|---|---|---|
| TPU Coated Fabric | Airtight, weldable, flexible, abrasion-resistant | Inflatable boats, bladders, air cushions, rescue gear, water sports products | Choose TPU when air retention, seam welding, soft folding and low-temperature flexibility are important. |
| PVC Coated Fabric | Cost efficiency, strong waterproofing, broad industrial availability | Large inflatable structures, covers, temporary air products, tarpaulin-based applications | Choose PVC when large-format waterproof coverage and budget control are key priorities. |
| PU Coated Fabric | Soft hand feel, lightweight coating, flexible textile appearance | Light bags, covers, soft goods and non-critical waterproof applications | Choose PU when the product is lightweight and strong airtight welding is not the main requirement. |
