Polyurethane (PU)


The PU series covers the polishing cloths made of polyurethane, which are available unfilled or either filled with ceriumoxide or zirconiumoxide.

In spite of a high stiffness the polyurethane cloth are very active due to their porous surface. The cloths of PU series stand out due to their long life time and the unique surface treatment. According to the polishing medium, best results in abrasion, flatness and finishin can be achieved.

Polyurethane cloths are suitable for several applications, e.g. glass, LCD, precision optics, quartz crystals odor semi conductor technics..
