These pads main application are for wafer polishing, glass polishing, hard disk, stainless steel, and copper sheet polishing.

POLYPAS #55 is a multi-purpose pad is used for low-pressure polishing.
This product main application is especially for glass polishing because it provides excellent flatness when used in the second polishing stage (following a first stage polishing with a harder pad).

POLYPAS #65 is a semi-soft type pad used for both low- and medium pressure polishing.
This product main application is especially in the first stage of polishing of silicon and GaAs wafers, photomask, and liquid crystal; providing scratch-free and haze-free results.

POLYPAS #75 is a standard pad used for medium-pressure polishing.
This product is designed to provide excellent flatness with pressure ranging from 300 to 600 g/cm2. This multi-purpose pad is ideal for polishing silicon and compound wafers, and ceramics.
