The flexible magnet strip is magnetic on one side and white vinyl coating on the reverse, and can be attached and easily repositioned on flat or slightly curved steel surfaces. The 200' roll is pre-scored every 4" (597 total pieces) to snap off easily, with a tolerance of + or - .060". The vinyl side can be written on directly with a wet-erase or permanent marker, or a pre-printed adhesive paper label can be attached. The strip withstands temperatures from -15 to +160 degrees F.Flexible magnets can be easily cut and shaped for a range of applications. They are produced by mixing powdered iron or ferrite with a rubber or plastic binder, and then extruding or rolling into the desired shape. Flexible magnets can have adhesive backing and be laminated with a printable vinyl coating. Flexible magnets are typically magnetized with multiple poles on one surface to generate a stronger holding force. High-energy flexible magnets can sometimes be used in place of ceramic materials if tight tolerances are not required. The application temperature range is determined by binder material properties.
