Rubber magnets are permanent magnets made by mixing synthetic rubber with ferrite power, then kneading and processing by extrusion molding. Rubber magnet material offer the product designer a uniquely desirable combination of properties at lower cost than other magnet materials. The flexibility and machine-ability of these magnets permit design innovations and automated manufacturing techniques.
Rubber magnets are commonly used for toys, switch, sensors and refrigerator door, due to low cost and unbreakable.
