PU-UF1

  • Food contact compliant
  • ATEX compliant
  • Clear and strong
  • Hygienic
  • Non-porous
  • Excellent chemical resistance

PU-UF1 is a transparent, high-gloss polyether-based thermoplastic polyurethane film developed by Filcoflex. It offers exceptional flexibility and durability, ensuring it does not fracture under constant flexing due to its "no memory" characteristic. The material's smooth, non-porous surface prevents material degradation and facilitates easy cleaning, making it ideal for hygienic applications.

PU-UF1 exhibits excellent abrasion and chemical resistance, including compatibility with CIP (Clean-In-Place) cleaning processes, and maintains integrity over time due to its superior aging resistance. Its thermoplastic properties allow for seamless welding and customization into various shapes and designs.

PU-UF1 can incorporate features such as integrated reinforcement rings, grounding options, and embedded identification tags (NFC/RFID), enhancing its functionality in complex systems. Its transparency facilitates visual inspection, ensuring process control and safety. This material combines mechanical strength, chemical resilience, and design versatility, making it a reliable choice for industries requiring stringent hygiene and performance standards.

Applications

Stationary, Vibratory, Gyratory, Sifters, Screeners, Feeders, Spray driers, Fluid Bed, Static Cool Bed, Bin dischargers, Hoppers, Conveyors, Packing equipment, Storage silos, Screw conveyors,
Valves, butterfly valves, Rotary valves, Tanks, Silo’s, any sort of product handling equipment, Air ducting , Fans, Inflatable seals, Covers, Outside protection sleeves, Bellows, Load cell (high volume, weight and capacity), Harmonica’s, Telescopic applications, Vacuum formed shapes.

Pressure Resistance for Flexible Connectors

Flexible Length up to 300mm
0,34 Bar / 5.0 PSI For temperatures up to 90 °C / 195°F
-0,2 Bar / -2.9 PSI For temperatures up to 90 °C / 195°F

These pressures may cause expanded or contracted shapes.
Filcoflex can additionally add reinforcement rings to reduce contraction or expansion of the cylindrical shape.
Please contact us for more information for higher pressures, higher vacuum, or longer lengths.

Weighing Applications

Very suitable for high volume weight and capacity weighing and dosing applications where the required accuracy is >1kg. If the required accuracy is <1KG, please contact Filcoflex and explore Weighing Flexible Connections like silicone bellows, poly urethane bellows, PU-UF03 sleeves or PTFE 310 fabric.

Chemical Resistance

  • CIP resistant (see CIP chemicals guide)
  • Cleaning Chemicals (see cleaning guide)
  • For a detailed chemical resistance please see our chemical compatibility chart

ATEX & Explosion Safety

PU-UF1 has been tested for its electrostatic properties, and has been found ATEX compliant and safe to use in all dust explosion hazardous areas, such as ATEX zones 20, 21, 22.*

Surface Resistance: 5 x 1012 Ω IEC 60093/EN1149 and TRGS 727
Volume Resistance: 3 x 1011 Ω IEC 60093/EN1149-1 and TRGS 727

No propagating brush discharges could be determined.
Non Conductive but safe to use up to a length of 1000mm.*

PU-UF1 has also been explosion pressure tested and found safe to up to an explosion pressure of 1,5 Bar up to a length of 300mm.

Availability for shapes, couplings and product features

PU-UF1 can be custom made in to almost any flexible sleeve and many other products.
