Product Categories
Product Fit
- Good fit when the top material is heat-sensitive or easy to mark.
- Useful when the finished part needs soft hand feel, flexibility and clean dry-film bonding.
- Not a universal replacement for standard TPU; final approval should be based on the buyer’s material stack and test method.
Recommended Applications
| Application Area | Typical Product / Bonding Position | What To Confirm |
|---|---|---|
| Heat-sensitive electronic covers | Tablet keyboard covers, PU leather cases, protective covers | Surface marking, edge lift, folding resistance and heat aging after bonding. |
| Soft textile and seamless parts | Seamless underwear edges, sportswear details, lightweight fabric bonding | Hand feel, strike-through, washing resistance and peel strength. |
| PU leather and microfiber goods | Decorative layers, lining bonding, microfiber or coated PU parts | Coating tolerance, flexibility and appearance after cooling. |
| Thin composite and die-cut lamination | Trim details, cosmetic boxes, local reinforcement or thin composite structures | Flatness, bubbles, shrinkage and dimensional stability. |
Suitable Bonding Materials
Common trial materials include PU leather, microfiber leather, coated leather, polyester fabric, nylon fabric, cotton blends, elastic textile structures, TPU film, PC, ABS and PET support layers. Difficult coatings, low-energy surfaces and plasticized materials should be tested before bulk order.
Selection Notes Before Sampling
| Selection Point | What To Check Before Sampling |
|---|---|
| Heat-sensitive surface | Confirm whether the surface marks, shrinks, warps or changes gloss at normal TPU bonding temperature. |
| Adhesive thickness | Use thinner film for smooth substrates; consider higher adhesive volume for rough, porous or textured materials. |
| Liner choice | Release paper is common; release film or liner-free handling should be confirmed by cutting, positioning and lamination process. |
| Trial condition | Start from the lowest effective bonding temperature, then confirm peel strength, edge lift and appearance after cooling. |
| Storage before trial | Keep samples sealed in a cool, ventilated place before testing to reduce dust, moisture and handling contamination. |
Sample Grade Selection
The grade direction below is based on VELNORA public model codes converted from the approved internal line-card data. Use it as a starting point for sample testing, not as a final guarantee for every substrate.
| Public Code | Material | Melting Point | Starting Service Conditions | Temperature Range | Sample Direction |
|---|---|---|---|---|---|
| ZF-1682 | Modified TPU | 65 C | 90-110 C, 0.1-0.4 MPa, 5-12 s | -20 C to 60 C | Lower-temperature trials for special metal, low-energy surfaces and heat-sensitive structures. |
| ZF-5180 | TPU | 75-80 C | 80-110 C, 0.1-0.4 MPa, 5-20 s | -20 C to 80 C | PU leather, microfiber, nylon, ABS, PC, TPU and textile bonding sample trials. |
| ZF-7325 | TPU | 75-80 C | 110-130 C, 0.1-0.4 MPa, 5-20 s | -20 C to 70 C | Electronic leather cases and textile bonding where a low-melting TPU option is needed. |
Processing and Sample Support
Start with the lowest effective temperature, keep pressure even, and test peel strength after cooling. For samples, send material names, photos, target thickness, required width, bonding machine, temperature limit and final test standard. To set and adjust a low-temperature grade on your press, see temperature, pressure and time settings by grade and substrate.
Quality Control Summary
Typical checks include thickness, width, roll appearance, liner release, melt behavior, sample bonding, peel strength and packing condition.
FAQ
When should I choose low temperature TPU film?
Choose it when the substrate is heat-sensitive but still needs TPU flexibility and clean bonding.
Can it bond PU leather and electronic covers?
Yes, these are common trial directions, but coating, plasticizer content and support-layer material must be tested.
Do you supply it with release paper?
Release paper is common. Release film or liner-free supply can also be reviewed by grade and handling process.
What information is needed for quotation?
Send substrate, application, thickness, width, liner requirement, order quantity and bonding conditions.

Send your material, application, thickness, working temperature and estimated quantity. VELNORA can recommend a low-temperature TPU film sample for testing.
Why Choose a Low-Temperature TPU Adhesive Film?
A low-temperature TPU adhesive film is selected when the substrate needs a lower activation direction than standard TPU bonding. The goal is to reduce thermal exposure on heat-sensitive textile, delicate coating, synthetic leather, foam composite or surface-finished material while keeping the flexibility expected from a TPU bonding film.
Excessive heat can create deformation, press marks, surface gloss change, coating damage or dimensional change on sensitive materials. For this reason, the buyer should share the substrate pair, visible surface, heat limit, bonding position and required softness so VELNORA can recommend a selected low-temperature grade direction.
