With a thickness of 0,7 mm, PU-UF07 strikes a balance between suppleness and mechanical strength. This transparent polyether Poly Urethane film from Filcoflex B.V. suits flexible components that move constantly but also have to withstand wear.
The material has no memory, so it handles continuous movement without cracking or permanent deformation. Its glossy, non-porous surface prevents degradation and contamination and makes cleaning simple. It is also suitable for CIP-cleaned installations.
PU-UF07 resists abrasion, many chemicals and aging well, so it stays reliable over a long service life. The thermoplastic film can be welded seamlessly and supplied in custom shapes. Integrated reinforcement rings, grounding provisions and NFC/RFID identification can be added. The transparency keeps product flow visible and supports safe, controlled operation.
See the “Downloads” section for certificates, compliances and the datasheet.
With its balance of flexibility and strength, PU-UF07 is a reliable material for components in the following equipment:
ATEX and explosion safety
No separate electrostatic test has been carried out on PU-UF07. Because PU-UF03, PU-UF1 and PU-UF15 are made from the identical Poly Urethane, with only the thickness being different, the PU-UF03 test results serve as the worst-case scenario for this grade. The usage restrictions in the table below therefore apply to PU-UF07 as well.
You can find the complete test report and declaration on the PU-UF03 material page.

| Airspeed | Minimum Ignition Energy | Maximum length | ATEX zone |
|---|---|---|---|
| < 2 m/s | > 1 mJ | 100mm | 20, 21, 22 |
| > 2 m/s | > 1000 mJ | 100mm | 20, 21, 22 |
Pressure resistance for flexible connectors
All pressure values in the specifications table apply up to 60 °C / 140 °F. Under pressure or vacuum, a flexible connector may bulge or contract. Filcoflex can add reinforcement rings to keep the sleeve in shape.
For higher pressures, higher vacuum or longer lengths, we are happy to advise.
Weighing applications
PU-UF07 is suitable for high-volume, high-weight and high-capacity weighing and dosing where an accuracy below 1 kg is required. For accuracies below 0,5 kg, Filcoflex offers dedicated weighing flexible connections, such as silicone bellows, Poly Urethane bellows, PU-UF03 sleeves and PTFE 310 fabric.
Availability of shapes, couplings and product features
PU-UF07 can be manufactured into almost any flexible sleeve, as well as many other custom-made products. Please contact us for the possibilities.
