The polishing pad is made by mixing nano-scale silica particles with a high-efficiency binder, and then uniformly coating the surface of the polyester film, and then drying and curing reaction.

The polishing pad is used for polishing the surface of the workpiece and the plating layer. The polishing wheel is divided into: polishing cloth wheel, hemp wheel, nylon wheel, wiring wheel, wind wheel, wool wheel, etc. There are many types.

Depending on whether it contains abrasives, polishing pad can be divided into abrasive polishing pads and non-abrasive polishing pads; Depending on the material, polishing pad can be divided into polyurethane polishing pads, non-woven polishing pads and composite polishing pads. According to different surface structures, it can be roughly divided into flat type, grid and spiral.

Polishing pads are also called polishing skins, polishing cloths, polishing pads, and are important auxiliary materials that determine the surface quality in chemical mechanical polishing.Polishing pads can be divided into abrasive polishing pads and non-abrasive polishing pads according to whether
