For applications that call for extra robustness, Filcoflex B.V. offers PU-UF15. This is a 1,5 mm thick transparent Poly Urethane film based on polyether TPU. The added thickness gives more puncture and wear resistance while the material stays flexible enough for dynamic use.
PU-UF15 is a strong candidate for flexible connectors and sleeves in powder and bulk handling, where abrasive products and continuous movement come together. Because it has no memory, it keeps flexing without cracking. Its smooth, glossy surface prevents product adhesion and is fully suitable for CIP cleaning.
The material keeps its integrity thanks to strong chemical and aging resistance. Thermoplastic welding allows seamless, custom-made constructions. Reinforcement rings, grounding/earthing and NFC/RFID tags can be integrated for traceability and safety. The clear material lets operators check the process at a glance.
Certificates and compliances for PU-UF15 can be found under "Downloads".
The extra thickness of PU-UF15 makes it a strong choice for abrasive and dynamic applications in:
ATEX and explosion safety
The electrostatic properties of PU-UF15 have been tested in accordance with IEC 60093/EN 1149 and TRGS 727. The table below gives an overview of safe use in the various ATEX zones. For the measured values, see the specifications table, or download the full “Electrostatic properties test report” from the Downloads section.
PU-UF15 is also the worst-case ATEX reference for the thicker grades PU-UF20 and PU-UF30.
| Airspeed | Minimum Ignition Energy | Maximum length | ATEX zone |
|---|---|---|---|
| < 2 m/s | > 1 mJ | 1000mm | 20, 21, 22 |
| > 2 m/s | > 1000 mJ | 1000mm | 20, 21, 22 |
Pressure resistance for flexible connectors
The specifications table lists pressure values valid up to 90 °C / 194 °F. Under these conditions, a sleeve may expand or contract. Reinforcement rings from Filcoflex help retain the cylindrical shape.
Get in touch for higher pressures, deeper vacuum or longer lengths.
Weighing applications
PU-UF15 is well suited for high-volume and high-weight weighing and dosing with a required accuracy above 1 kg. For accuracies below 1 kg, Filcoflex offers weighing flexible connections such as silicone bellows, Poly Urethane bellows and sleeves made from PU-UF03 or PTFE 310 fabric.
Availability of shapes, couplings and product features
PU-UF15 can be made into almost any flexible sleeve, with a wide choice of couplings and features. Contact us for the possibilities.
