Primarily used in soft polishing processes, PU-impregnated polishing pads are classified into three density grades, determined by the weaving method of the fibers and the polyurethane (PU) content. Various groove patterns can be applied to tailor the surface for specific polishing performance.

These pads are compatible with different polishing slurries and are ideal for soft polishing applications involving optoelectronic components (such as Sapphire and Silicon wafers), glass components, and metal parts. They play a key role in improving surface flatness and removing scratches, making them an essential part of precision polishing processes.
