Beschreibung
Zusammenfassung:	Disclosed are: a polishing medium in a form of bristles made from porous, non-porous, or minimally porous polymer-based materials; a device and system comprising the medium; and a method for constructing and using the medium, device, and system. An exemplary method for manufacturing bristles for use in polishing a workpiece which includes a non-planar surface comprises the steps of: forming a polymeric material by combining a liquid polymer comprising a TDI polyester prepolymer having an NCO content of about 5% with a curing agent; separating the foamed polymeric material into a plurality of bristles; and stitching the bristles onto a platen. 다공성, 비다공성, 또는 최소 다공성 고분자 기반 재료로 만들어진 강모 형태의 연마 매체, 매체를 포함하는 장치 및 시스템, 및 매체, 장치, 및 시스템 형성 및 사용 방법이 개시된다. 비평면 표면을 포함하는 공작물 연마에서 사용하기 위한 강모 제조의 예시적 방법은 5% 범위의 NCO 함량을 갖는 TDI 폴리에스테르 예비고분자를 포함하는 액체 고분자를 경화제와 조합하여 고분자 재료를 형성하는 단계, 발포된 고분자 재료를 복수의 강모로 분리하는 단계, 및 강모를 플래튼에 스티칭하는 단계를 포함한다.
