Flexible Rubber 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.
