Polishing felt POLYCON

With POLYCON polyurethanes, we have added to our product range a range of well-balanced black polishing cloths specially developed for pre-polish, intermediate and final polish for critical surface finishing jobs.

The polishing cloths of the POLYCON series are available as standard by the meter or as punched discs.

All materials are available in the "plain" (non-adhesive back) and "PS" (adhesive back) versions.
