ABSTRACT:
A method for polishing articles manufactured from silicone rubber or silicone elastomers is disclosed. This method includes tumble-polishing in a receptacle charged with polishing objects, an alcohol solvent, and silicone articles for a period of time and at a rotation speed sufficient to remove surface irregularities and produce the desired finish and/or improve the optical transparency of the silicone articles. This method is particularly useful in the polishing of biomedical articles such as intraocular or soft contact lenses, tips of cannulae, and articles such as O-rings for precision mechanical devices.
