Flexible Magnets, also known as rubber magnets,are a composite of resin, magnetic powders and other different materials. They are produced in flat strips and sheets. They can be used for refrigerator doors, toys and teaching materials.
1.Flexible magnet covers a wide variety of magnetic materials. The most common constituents in Flexible ferrite magnet material Barium Ferrite and Strontium and, more recently, in rare earth Flexible material, Neodymium Iron Boron, all loaded into PVC binders.
2.Most Flexible magnet material is produced in strip or sheet by extrusion process. Higher magnetic characteristic/performance. Flexible material is obtained either by work rolling/hardening in the rolling process or by including special additives to the chemical constituent.
3.Flexible materials has a particular steady magnetic power and a smooth surface, which is a uniquely desirable combination of properties for many product designer with a lower cost, especially in flexibility and mach inability, no other magnetic materials has this characteristic comparable to it.
4.Flexible materials is enough soft to be easily bent, twisted, coiled, punched, and otherwise machined into almost any shape without loss of magnetic energy.
