Abstract

See full text

Polishing media in the form of bristles made from a porous polymer-based material, apparatus and systems including the media, and methods of forming and using the media, apparatus, and systems are disclosed. A method of manufacturing bristles for use in polishing a workpiece which includes a non-planar surface includes the steps of combining a liquid polymer material and a foaming agent to form a foamed polymeric material, and separating the foamed polymeric material into a plurality of bristles. The foaming agent is configured to impart a porosity to the polymeric material, where the porosity is characterized by a density in the range of 0.3 to 1.2 g/cm3.
