Anisotropic flexible rubber magnets are made by mixing ferrite magnet
powder with synthetic rubber or plastic. When barium or strontium
ferrite powder are consolidated with polymer matrix, anisotropic
flexible rubber magnets are produced. The magnets so produced, have an
excellent flexibility in permanent magnetic material field. These
magnets because of their flexible feature can be easily molded and cut
into stripes without affecting their magnetic properties. They also have
an excellent machining characteristics. Features
- The magnetic properties of the flexible rubber magnets are higher
than that of sintered isotropic ferrite magnets.
- It is easy to give desired shapes to the magnetic rubber as the
punching, cutting, perforating and bending are easy and simple.
- The density is lower than that of sintered ferrite magnets.
- The flexibility of the magnets prevents it from cracking or
breakage.
- They have good resistance to demagnetization.
- Average temperature stability.
The different applications of flexible rubber magnets are :
- Advertising
- Motors
- Sensors
- Learning material
- Decoration magnets for refrigerator
- Magnets for toys
- Vehicle signage
- Shelf and bin marking
- Craft, hobby, and toys
- POP displays
