Selection of Spartan Pads for Application-Specific Environments Ver 2 (pdf) – Much has been written about the polishing process especially the interface of pads, specific slurries and equipment for applications involving optics and semiconductor materials. My focus is on how various Spartan Polishing Pads can address applications-specific requirements. At Spartan Felt Company we manufacture synthetic materials that are best suited for industrial, optic, electro-optic, semiconductor, compound semiconductor and advanced materials surface preparation.

HP®-Media-Technical-Bulletin-V6 (pdf) – An Innovative Polishing Media Polishes Hard Metals Faster and with Improved Accuracy. A synthetic polishing felt has been found to significantly improve the ability to polish a titanium alloy and 316 stainless steel over wool. Spartan High Performance (HP®) products are the only synthetic media of its kind, with properties that improve polishing results and efficiency. With high heat resistance and low heat absorption, HP® media can withstand the stress of friction heat longer than wool, or any other media tested. Polishing tools made with HP® media can be driven under much higher pressure to remove material from the surface being polished, improving efficiency. Tools can also be shaped to match a profile of a part and will maintain the shape during the polishing process. This results in a more even amount of material being removed from the substrate surface, so the chance for deformation from polishing is considerably reduced. HP® media can be impregnated with abrasives, which eliminates the need and mess of compounds. And it is not affected adversely by water, so polishing tools can be used in CNC or similar processes that are wet from cooling water. Wool, however, was found to be more effective in achieving mirror finishes, and though HP® media will finish faster and more evenly, wool is recommended as a final step in cases where mirror finishes are required.
