Flexible Magnets

 

What are Flexible Magnets?

Flexible magnets contain magnetic particles captive inside a flexible polymer binder. Flexible magnets are used for unique applications that would not be possible using other ‘hard’ magnets.

How Flexible Magnets made

A dry mixture of ferrite powder and rubber polymer resin is mixed, calendared and ground; then formed either by extrusion (for magnetic strip) or rollers (for magnetic sheeting). The material is then magnetized, laminated with vinyl or adhesive, cut to size, rolled onto a core, and boxed for shipment.

Flexible Magnetic Sheets

Flexible magnetic sheet is magnetised on one side only with very fine stripes of north-south-north-south polarity running down the length of the sheet. The non-magnetic side is often laminated with white vinyl or adhesive. The sheets are very flexible and can easily be cut with a trimming knife or scissors.

Magnetic sheets are naturally a brown colour.

How magnetic tiles are made

The sheets can be ‘die cut’ using a roller press and a series of sharp ‘knife type’ cutting blades which are set into a board and are arranged to form multiple sets of the desired shape. Using this technique, many identical simple shapes can be cut quickly with ease.

Vehicle Magnets

Vehicle magnets have a UV protection layer which is not in all flexible magnets.

Vehicle magnets are often used cars. Taxis and driving school livery can be easily added and then removed when the car is used privately. The same is true for company cars showing company logos in the week, which are then removed at weekends. In these applications, meticulous cleaning and flat storage are essential to prevent attracted ferrous particles getting attracted to the magnetic surface of the sign and then becoming trapped in between the sign and the car. Good housekeeping will maintain the car’s paintwork.
