Polishing Pads


Soft pad, dual pore structure
on compressible substrate

The OPTIVISION™ 4540 has a dual pore structure; a combination of small pores dispersed amongst larger pores. This pore structure is advantageous over other finishing pads due to the increased number of contact points. The increase in contact area and number of contact points results in lower defectivity, increased removal rate, and improved surface finish.


Dual pore structure

Various surface textures available such as grooved, embossed, plain, and perforated
