Flexible Magnets, form of bonded ferrite magnets, are compounded of magnetic ferrite powder and binder materials. (synthetic resin, additives)They are versatile in shape, precise dimensions and flexibility and may be formed into many shapes: strip, ring, sheet, coiled, particles and various geometric figures. The surface can be UV oil coated, spray lacquered, printed, with adhesive tape or with PVC or paper pressed on them.

Key Benefits

• Inexpensive
• Available in wide sheets and in extruded strips
• Easy to adhere to products
• Easy to cut and shape
• Can be supplied with colored laminates
• Sheet materials laminated with vinyl can be imprinted using silk screening or digital printing techniques
• High Energy grades are as strong or stronger than Ceramic 1 grade

Key Challenges

• Standard materials are only magnetic on one side
• Magnetically weak compared to other hard magnets
• Use at temperature below -40⁰C~80⁰C limited due to binder material stability
• Environmental conditions can degrade binder and cause brittleness and cracking
