SUBA™ polishing pads are polyurethane impregnated polyester felts. They are speciically designed for stock and intermediate polishing
where achieving a high precision surface is critical. SUBA™ pads should be used in combination with each other and with inal polishing
pads to produce a haze-free, low defect inish in dual or multi-step processes. SUBA™ pads are ideal for a w ide variety of materials
including semiconductor wafers, glass, ceramics, special metals and plastic.
SUBA™ IV features an open pore structure and a l ess aggressive urethane composition than the other SUBA™ pads. These qualities
