The thickest grade in the range, PU-UF30, is a 3,0 mm transparent polyether Poly Urethane sheet by Filcoflex B.V. It suits parts that have to withstand high mechanical loads, impact and intensive abrasion, without losing the flexibility and hygiene benefits of TPU.
Even at this thickness the material has no memory, so it absorbs repeated movement without stress cracking. The high-gloss, non-porous surface resists contamination and product build-up, and it can be cleaned with CIP systems. That makes PU-UF30 suitable for demanding hygienic environments.
Long service life comes from its excellent resistance to wear, chemicals and aging. Like all PU-UF grades, it is thermoplastic and weldable, so custom shapes and seamless constructions are possible. Reinforcement rings, grounding/earthing and NFC/RFID tags can be integrated on request. Its transparency keeps the process visible for inspection and safety.
All certificates and compliances are listed in the “Downloads” section.
With its wide temperature range and high elasticity, PU-UF3 is used in many types of process and bulk handling equipment:
ATEX and explosion safety
PU-UF3 has been tested for its electrostatic properties in accordance with IEC 60093/EN 1149 and TRGS 727. It is ATEX compliant and safe to use in dust explosion hazardous areas, including ATEX zones 20, 21 and 22, at lengths up to 1000 mm. The table below shows how and where the material can be used safely. For the tested values, see the specifications table and the “Electrostatic properties test report” in the Downloads section.
| Airspeed | Minimum Ignition Energy | Maximum length | ATEX zone |
|---|---|---|---|
| < 2 m/s | > 1 mJ | 1000mm | 20, 21, 22 |
| > 2 m/s | > 1 mJ | 1000mm | 20, 21, 22 |
PU-UF3 has also been tested for explosion shock pressure resistance and is safe up to an explosion pressure of 1,5 bar at lengths up to 300 mm.
Pressure resistance for flexible connectors
The values in the specifications table apply at temperatures up to 90 °C / 194 °F, for flexible lengths up to 300 mm. At these pressures, the sleeve may expand or contract. Filcoflex can integrate reinforcement rings to limit this deformation.
For higher pressures, higher vacuum or longer lengths, please contact us.
Weighing applications
PU-UF3 is well suited for high-volume and high-weight weighing and dosing applications with a required accuracy above 1 kg. Need an accuracy below 1 kg? Contact Filcoflex to explore weighing flexible connections such as silicone bellows, Poly Urethane bellows, or sleeves made from PU-UF03 or PTFE 310 fabric.
Availability of shapes, couplings and product features
PU-UF3 can be custom made into almost any flexible sleeve and many other products. Contact us to discuss the options of the shapes, couplings and features for your application.
