Rubber Magnet Magnetic Property

Rubber Magnet Magnetic Property

Rubber Magnets, also named flexible magnets, are made from ferrite magnet powders, plastics (such as Nylon, PP,PVC, etc.) and other materials by rolling, extruding or injecting. These compounds can be easily made into required shape, even size, such as strip, roll, sheet and other complicated shapes. Also it is very easy to incise, stiletto, slit on them because these magnets have good plasticity. They can be used in Advertising Vehicle signage(Named Magnetic Signs), Shelf and bin marking, Craft, decoration items, toys, and Surface masking, etc.

Good plasticity
Can be easily folded, twisted without losing its magnetic power
Low price because plentiful raw materials
High corrosion resistant

Available In roll, strip roll, sheet, etc
Isotropic and anisotropic rubber magnets available
Available with PVC, Pressure Sensitive adhesive,
UV coating is available for outdoor using and anti-stick when stacked on.
Custom made
