PU-W1

  • Blocks light
  • Opaque white material
  • Food contact compliant
  • Hygienic
  • Non-porous
  • Great chemical resistance

PU-W1 is a white, matte-finish polyether-based thermoplastic polyurethane film developed by Filcoflex. Designed for applications where transparency is not desired, it effectively blocks light for processes sensitive to light exposure. The material exhibits exceptional flexibility and durability, resisting fractures even under constant flexing due to its "no memory" characteristic. Its smooth, non-porous surface ensures hygienic conditions, making it ideal for food processing environments. PU-W1 complies with international food contact regulations, including FDA 21 CFR 175.105, 1680, and 177.2600, as well as EU directives (EC) 1935/2004 and 10/2011. Additionally, it offers excellent chemical resistance, including compatibility with CIP cleaning agents. The material's thermoplastic properties allow for seamless welding and customization into various shapes and designs, including flexible connectors and sleeves. Its white coloration also allows for the integration of transparent viewing windows when visual inspection is needed.

PU-FW1

A white Poly Ether Urethane Thermoplastic film. PUW1 is not transparent nore translucent can can therefor be used where light may not enter the process, or where sight is less wanted.
Having no memory PU W1 will not fracture as a result of constant flexing.

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

0,34 Bar / 5.0 PSI For temperatures up to 90 °C / 195°F. Please see “Operating Pressure Guide” for further information. We recommend using the shortest possible connector for applications where increased pressure and/or high temperature is expected. Please contact us for more information.

Weighing Applications

High volume weight and capacity weighing and dosing applications please see “weighing and dosing guide” for further information.

Chemical Resistance

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