Flexible Plastic Magnets Overview

Flexible (Rubber) magnets are made by mixing ferrite or Neodymium magnet powders with synthetic or natural rubber binders in rolling (calendaring) or extrusion process. Flexible magnets are advantageous due to their versatility, low cost, and ease of use. Flexible (Rubber) magnets are usually manufactured in strip or sheet form and are widely used in micro-motors, gaskets, novelties, signs, and displays. Ferrite flexible (Rubber) magnet materials have a very low energy product (0.6MGOe to 1.7MGOe). No surface treatments are necessary for flexible magnets. Ferrite based flexible materials are often laminated with white or colored printable vinyl. They can also be manufactured with pressure sensitive adhesives to make assembly easy.

 

Key Advantages

· In sheet or strip form

· Cut and shape easily

· Relatively cheap

· Higher energy flexible materials allows it to replace ceramic materials

· Adhere to products easily

· Silk screening or digital printing techniques can be used in imprinting sheet materials laminated with vinyl

Quick Leads

· Manufacturing process - extruding or calendaring

· Main shapes - slit, cut, punched or coiled strips and wide sheets

· Energy Product: 0.6 MGOe to 1.7MGOe for ferrite based materials

· Commonly magnetized with multiple poles on one surface so as to generate a stronger holding force
