PU-W1

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.

Production Methods used

Joining / Bonding:

• Welding
  • HF high frequency welding
    Welding the material and cooling it down under compression with Radio Frequency to make the TPU material flow nearly seamless to form a uniform thickness with the original material wall thickness.
  • Heat contact – with silver alloy heating element
    Welds are welded surface to surface after which the weld are compressed while cooling.
  • Hot air – hot filtered and conditioned contaminent-, oil- and greas- free compressed air

Cutting:

• Stainless Steel knives
• Water Jet cutting

Availability for shapes, couplings and product features

PUW1 can be custom made in to almost any flexible sleeve and many other products. This document summarizes all the different shapes, end couplings and product features that are available for this flexible material.
