What Is a TPU Membrane?
A TPU membrane is a thermoplastic polyurethane film used as a functional layer in flexible products. Depending on formulation and structure, it can support waterproofing, moisture vapor transfer, weldability, elasticity, abrasion resistance, soft hand feel and lamination compatibility.
Not every buyer means the same product when they say “TPU membrane”.
For an outdoor garment mill, TPU membrane often means a thin breathable layer laminated between fabrics. For a waterproof bag factory, it may mean a clear weldable polyurethane film. For an inflatable product manufacturer, the functional layer may be part of a TPU coated textile that needs airtight seams. For a medical converter, softness, barrier behavior and skin-contact structure may matter more than total thickness alone.
DERFLEX treats TPU membrane as a material platform instead of a single SKU. Our team helps buyers define film chemistry, thickness, hardness, surface finish, roll width and downstream process before bulk orders.
Typical buyer questions DERFLEX helps answer
- Should the project use a breathable hydrophilic film, a clear barrier film or a textile-laminated structure?
- Is polyether TPU or polyester TPU more suitable for the working environment?
- Will the membrane be laminated, heat pressed, HF welded, hot-air welded, die-cut or used as a standalone film?
- What tests are needed before purchase: MVTR, hydrostatic pressure, peel strength, tensile, elongation, abrasion or seam leakage?
- How should roll length, core, anti-blocking finish and packaging be controlled for repeat OEM production?
TPU Membrane Types for Different Finished Products
The right TPU membrane depends on the finished product, not only on film thickness. The comparison below helps procurement teams prepare a practical request before sampling.
| TPU membrane direction | Functional focus | Common applications | Buyer selection notes |
|---|---|---|---|
| Waterproof breathable TPU membrane | Liquid-water barrier direction with moisture vapor transfer | Outdoor jackets, sportswear, gloves, footwear liners, mattress protectors, selected medical backing structures | Check MVTR, hydrostatic pressure and hand feel after lamination, not only on the standalone film. |
| Clear TPU film roll | Transparency, flexibility, abrasion resistance and waterproof sealing | Waterproof bags, inspection windows, hydration bladders, protective layers, inflatable parts, transparent soft components | Surface finish, anti-blocking, roll tension and weldability should match the converting line. |
| Polyether TPU membrane | Humidity, water contact, hydrolysis resistance and soft low-temperature flexibility direction | Water sports gear, dry bags, medical air products, outdoor wet-use equipment, water bladder structures | Consider this route when repeated humidity or water contact is a key concern. |
| Polyester TPU membrane | Abrasion, mechanical strength, selected oil-contact direction and robust surface behavior | Industrial covers, technical bags, protective sheets, selected bladders, workwear and equipment components | Finished product testing is important when oil, chemicals, heavy abrasion or long-term folding is involved. |
| TPU laminated fabric | TPU film bonded with textile layers for structure, comfort or reinforcement | Outdoor apparel, medical textiles, softshell fabric, bedding protection, footwear and technical composites | Substrate choice, adhesive system and lamination temperature can change final performance. |
| TPU coated fabric | Textile strength plus waterproof, airtight and weldable TPU surface | Inflatable boats, air bladders, flexible tanks, dry bags, rescue gear, industrial ducts and covers | Define base fabric denier, coating side, GSM, welding route, seam design and pressure requirement. |
Why TPU Membrane Is Chosen for Flexible Products
TPU membrane is valued because it can combine protection and flexibility in thin, roll-to-roll material structures. DERFLEX recommends testing the final laminate or welded product before bulk production, because fabric, adhesive, welding settings and end-use conditions all affect the result.
Waterproof Barrier Direction
TPU film can support liquid-water resistance in laminated textiles, bags, covers and flexible barriers. Hydrostatic performance should be measured on the final product structure.
Moisture Vapor Transfer
Hydrophilic TPU membrane can be designed to move water vapor through the film direction, helping breathable garments or selected medical structures reduce trapped humidity.
Soft Elastic Feel
TPU offers rubber-like flexibility with plastic-processability, making it practical for stretch fabrics, wearable products, inflatable parts and flexible transparent components.
Weldable & Heat Processable
Many TPU film and coated fabric structures can be evaluated for HF welding, hot-air welding, heat sealing, lamination or hot-melt bonding depending on grade and thickness.
Abrasion & Folding Resistance
For bags, covers, bladders and protective layers, TPU can support repeated folding and surface durability when the right chemistry and thickness are selected.
Custom Roll Production
Thickness, width, hardness, color tint, matte or glossy surface, anti-blocking finish and packaging can be discussed for OEM roll supply.

How to Choose a TPU Membrane Supplier
A reliable TPU membrane purchase should be based on application review, sample testing and repeatable production control. DERFLEX helps buyers move from a rough idea to a practical specification.
For textile laminators
Start with the finished laminate target.
Send the outer fabric, inner fabric, adhesive method, lamination temperature, wash requirement, target waterproof rating, target MVTR and hand-feel expectation. TPU film performance may change after lamination, so final fabric testing is recommended.
For bag and inflatable factories
Start with welding and seam behavior.
Share HF welding, hot-air welding or heat-sealing equipment details, seam width, pressure requirement, folding route and product size. Film thickness alone cannot confirm whether a finished product will seal reliably.
For medical and care product converters
Start with comfort, barrier and conversion method.
Confirm skin-contact layer, adhesive system, sterilization or packaging process, target softness, liquid barrier direction and moisture management requirement before sample evaluation.
For industrial OEM projects
Start with working environment.
Water contact, oil contact, chemical exposure, UV, abrasion, low temperature, pressure, folding and service time all influence TPU chemistry and fabric structure. A sample trial should reflect real operating conditions.

TPU Membrane Questions from Buyers
Use these answers to prepare your inquiry and choose the right TPU membrane direction for sample testing.
Is TPU membrane waterproof and breathable?
Selected hydrophilic TPU membrane grades can be designed to support a liquid-water barrier direction while allowing moisture vapor transfer. The final waterproofness and breathability should be tested after lamination or conversion, because substrate, adhesive and processing all affect performance.
What is the difference between TPU membrane and TPU coated fabric?
TPU membrane usually refers to a film layer supplied as a roll or laminated inside a composite. TPU coated fabric is a reinforced textile with TPU applied to one or both sides, used when the finished product needs textile strength plus waterproof, airtight or weldable performance.
Should I choose polyether TPU or polyester TPU?
Polyether TPU is often considered for humidity, water contact and hydrolysis resistance. Polyester TPU is often considered for abrasion resistance, mechanical strength and selected oil-contact directions. The right choice depends on final application, processing method and testing results.
Can DERFLEX customize TPU membrane thickness and width?
Yes. DERFLEX can discuss custom thickness, width, hardness, finish, color tint, roll length and packaging according to the application and production plan. Final availability depends on grade, MOQ and sample confirmation.
Can TPU membrane be welded?
Many TPU film and TPU coated fabric structures can be evaluated for HF welding, hot-air welding or heat sealing. Welding performance depends on TPU grade, thickness, surface, reinforcement, machine settings and seam design, so trial testing is recommended.
What information should I send for a quotation?
Please send the finished product application, target thickness or GSM, width, hardness, surface finish, color, substrate, lamination or welding method, test requirements, roll length, quantity estimate and any current material sample or specification.
Can TPU membrane replace PVC film?
TPU can be a suitable direction for some flexible products that need soft feel, elasticity, abrasion resistance, weldability or a PVC-free material route. However, PVC and TPU have different cost, processing and performance profiles, so replacement should be confirmed by sample trials and finished product testing.
