| Appearance | Transparent or translucent film, depending on grade and thickness. |
| Liner / handling | Release paper is common; release film or liner-free handling can be selected by grade and converting method. |
| Supply form | Full roll, slit roll, sheet or die-cut adhesive piece. |
| Storage | Keep sealed in a cool, ventilated place, around -20 C to 45 C / 10%-95% RH based on approved model reference. |
Sample Grade Selection
The following public model codes are sample directions from the approved VELNORA model reference. They help buyers choose a starting specification by bonding temperature, service condition and automotive interior part type.
| Public Code | Material | Melting Point | Starting Service Conditions | Temperature Range | Best Used For |
|---|---|---|---|---|---|
| ZF-6235 | TPU | 95-100 C | 160-200 C, 0.1-0.4 MPa, 10-20 s | -40 C to 100 C | Automotive interior trim, door panel inserts and higher-temperature soft-trim bonding direction. |
| ZF-6238 | TPU | 95-100 C | 120-140 C, 0.1-0.4 MPa, 5-20 s | -20 C to 80 C | PU leather, microfiber, ABS/PC support layers and general trim lamination. |
| ZF-5180 | TPU | 75-80 C | 80-110 C, 0.1-0.4 MPa, 5-20 s | -20 C to 80 C | Lower-temperature direction for soft decorative layers and selected heat-sensitive materials. |
Processing and Custom Supply Support
