SUBA™ 800

Felt polishing pad

SUBA™ polishing pads are polyurethane impregnated polyester felts. They are specifically 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 final polishing pads to produce a haze-free, low defect finish in dual or multi-step processes. SUBA™ pads are ideal for a wide variety of materials including semiconductor wafers, glass, ceramics, specialmetals and plastic.


Base material  Felt

Shelf life  12 months

Packaging  Pads are packaged face-to-face (polish side to polish side) and sealed inside a plastic bag to ensure cleanliness during transportation. The bags are taped to the side of the box to prevent the bag from slipping and damaging the pads. Pads should always remain flat. Bending pads during handling can cause wrinkles in the PSA and premature delamination of the release liner.

Applications  Sapphire
