The flexible magnet sheet is magnetic on one side and adhesive on the reverse, and can be adhered to flat, lightweight items to make them magnetic. The sheet has a strength rating of 60 pounds of pull per foot. The adhesive backing has a peel-off liner, which protects the adhesive from exposure to air until ready for use. The sheet withstands temperatures from 0 to 150 degrees F and can be cut with scissors, knife, or die. A project idea sheet is included.
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.
