Self-cleaning Polyurethane Screen The Polyurethane Screen cloths not only improved the quality but also minimised blinding, improved efficiency and have great wear. this provides the site with longer periods between changeover and less downtime during busy screening periods. Polyurethane Tufflex Screens have been documented to last up to 10 times longer than traditional woven wire screens, because the flexible and smooth nature of the materials allow it to move with the passing material. The impact effect is reduced, allowing longer wear life. The flexibility of the screen prevents sticking and blinding. Thus, the screens continue to perform at maximum efficiency without having to stop for cleaning. The increased run time adds up to considerable volume upside across the year for the same overhead cost structure.
