Rubber magnets are flexible magnetic materials made by combining ferrite magnetic powders with synthetic rubber through extrusion, calendering, injection molding, or similar processes. They can be bent or cut at will, feature moderate magnetic strength, are lightweight, and easy to process. They can be made into rolls, sheets, or custom shapes, with optional surface coatings or films. Rubber magnets are widely used in fridge magnets, stationery and educational tools, advertising signs, door and window sealing strips, and small motor components.
