Flexible (rubber) magnets are composed of Strontium ferrite or Barium with synthetic rubber or PVC matrixes and then are extruded to sheets with the properties and desired dimensions, such as sheets, strips and other special shapes. Magnetic sheets can be made with different topcoats that are typically applied to the non-magnetic side and most used laminates are PVC or adhensive depending on the required function of the magnets.
Applications: Advertising, craft and hobby, displays, sales promotions, graphics, nameplates, menu boards, toys, vehicle signage, doors as well as refrigerators, vibrations, sensors, switches and micro motors etc.
