Beschreibung
Zusammenfassung:	Polishing media in the form of bristles made from a porous, non-porous, or minimally porous polymer-based material, apparatus and systems including the media, and methods of forming and using the media, apparatus, and systems are disclosed. An exemplary method of manufacturing bristles for use in polishing a workpiece which includes a non-planar surface includes the steps of combining a liquid polymer comprising a TDI polyester pre-polymer having an NCO content in the range of 5% with a curative to form a polymeric material, separating the foamed polymeric material into a plurality of bristles, and stitching the bristles onto a platen.
