Flexible ribbon Magnets
Flexible ribbon Magnets Overview
Rubber magnet is a magnet compounded by magnetic powder and high polymer materials through the special craft. It has some advantages in magnet shaping, size precision, flexibility etc. It can be bent,twisted, coiled,punched, and otherwise machined into almost any shape without loss of magnetic energy. Standard grades of flexible materials have energy products from 0.6MGOe to 1.6 MGOe.

Key Advantages
- In sheet and strip form
- Cut or shape easily
- Relatively cheap
- Higher energy flexible materials may sometimes replace Ceramic 1 materials
- Adhere to products easily
- Silk screening or digital printing techniques can be used in imprinting sheet materials laminated with vinyl
Manufacturing Method
Extrusion involves squeezing heated compound through a shaped die, cooling the shaped material as it exits the die, and magnetizing the material. The standard grade materials are only magnetic on one side.
Calendering involves squeezing the compound between rollers to compress and flatten it to form a sheet. The sheet is fed through sets of rollers several times until it reaches the desired thickness. It is then slit to the desired width and magnetized. The standard grade materials are only magnetic on one side.
Applications of Rubber Magnet
- Small-size precise motor
- Refrigerator door sealing strip
- Bathroom door sealing strip
- Toy
- Stationery
- Advertisement propaganda
Shapes, Sizes, and Grades Available
Standard stocked shapes include strip and sheet in the lower energy grades, strip and a variety of punched parts in ring, disc, and bar shapes in the higher energy grades. Non-standard shapes and sizes can be fabricated to blueprint specifications from raw stock. Non-standard profiles of the 0.6 MGOe material can be extruded by fabricating special dies.
Surface Treatments
No surface treatments are required to protect against corrosion. We are able to laminate a variety of decorative facings to magnetic strip,such as PVC( white PVC, matte white-PVC, and gloss white-PVC and color PVC, such as red, yellow, black, brown, etc),self adhesive(standard adhesive and 3M adhesive), and UV.
Magnetizing and Handling
Low energy flexible ribbon magnets are magnetized with multiple poles on one surface to give greater holding force. Higher energy flexible ribbon magnets are magnetized either multiple pole, or single pole on one surface. No special handling precautions have to be taken with flexible ribbon magnets since they are relatively weak magnetically, and are not brittle.
Temperature Effects
Magnetic properties of flexible magnets degrade linearly with temperature in the same way as Ceramic magnets. However, the limiting factor for flexible magnets are the binder materials used to render them flexible: these begin to flow at temperatures of about 250 F.
