Flexible Plastic Magnets
Flexible Plastic Magnets Overview
Flexible (Rubber) magnets are made by mixing Ferrite or Neodymium magnet powders and synthetic or natural rubber binders. Flexible (Rubber) magnets are made by rolling (calendaring) or extrusion methods. Flexible magnets are applied because of their advantages of versatility, low cost, and ease of use. Flexible (Rubber) magnets are usually manufactured in strip or sheet form that is widely used in micro-motors, gaskets, novelties, signs, and displays. Ferrite flexible (Rubber) magnet material is very low energy and its energy product is from 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, or with pressure sensitive adhesives to make assembly easy.

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
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
