Flexible Magnets: Principles and Applications

Chapter 1: Understanding the Principle of Flexible Magnets

In this chapter, we’ll explore the fundamental concepts of flexible magnets, delving into their production process and how they function.

Defining Flexible Magnets

Flexible magnets are composite materials where magnetic particles are set within an elastomer matrix. They are manufactured by blending rubber polymer resin with ferrite powder, which is then shaped using either extrusion or rolling techniques. The final steps involve magnetizing the material and applying a vinyl or adhesive laminate.

These magnets benefit from combining the flexibility of rubber with the magnetism of elastomers, making them suitable for a wide range of technical applications.

As their name suggests, flexible magnets are designed to be pliable and adjustable, catering to specific application needs. They can be easily cut into various shapes, making them ideal for custom and specialized applications.

Flexible magnets find applications across different industries, from manufacturing to households, schools, and businesses. Their flexibility allows them to adapt to diverse uses and can be shaped during or after production. Typically, flexible magnets are manufactured through calendering or extrusion.

While flexible magnets provide unique benefits over traditional solid magnets—like adaptability and customizability—they may not be as durable in specific contexts. Collaborating with a trusted and experienced manufacturer is essential to ensure that you receive solutions tailored to your application’s specific requirements.

Manufacturing Flexible Magnets

Flexible magnets are often divided into two primary types based on their production methods: magnetic sheets and extruded magnetic profiles.

Extruded Magnetic Profiles and Tapes

Extruded flexible magnets can be made into profiles that are rolled into coils, commonly in lengths of 33 or 98 feet (10 or 30 m), and used in products like shower doors or refrigerator seals. The cross-section of an extruded profile may have intricate shapes allowing it to fit securely into a corresponding aluminum extrusion with only the front side magnetized and visible.

During production, the granular material is heated until melting and then pressurized with a screw feed through a hardened die, electrically discharge machined (EDM) to the desired profile shape. As the material exits, it cools and passes over a magnetizing fixture imparting a two-pole or multi-pole magnetic pattern.

Most flexible magnets are magnetized with pole strips on one side, leaving the other side non-magnetic. Extruded profiles may be rectangular, creating magnetic strips often termed magnetic tape, which can be laminated on the non-magnetic side with high-quality double-sided adhesive tape. Identical strips can be magnetized with matching polarities, allowing them to align perfectly, such as one with NSNSN and the other SNSNS.

Flexible Magnetic Sheets

Magnetic sheets are produced via calendering, generally available in widths up to 24 inches (610 mm) and lengths of 98 feet (30 m), with a typical thickness ranging from 0.02 to 0.03 inches (0.5 to 0.76 mm). These sheets are frequently used in point-of-sale displays and advertising, such as vehicle graphics for taxis and driving school cars, which can be easily attached and removed based on the vehicle’s use.

This concept applies to company vehicles displaying logos, which might be removed during non-business hours. For such uses, it’s critical to maintain cleanliness and store the sheets flat to avoid ferrous particles clinging to the magnetic surface and damaging the vehicle's finish.

Magnetic Graphics System

A magnetic graphics system enables the easy updating of variable information or graphics without replacing the whole sign or display.

Characteristics of Flexible Magnets

Powerful flexible magnetic sheeting is strongly magnetized with a multi-pole magnetization pattern, providing consistently distributed magnetic strength across its surface. Generally, thicker materials deliver stronger magnetic abilities.

The magnetism is permanent, so long as the magnet is not exposed to demagnetizing forces or larger magnets.

To summarize, flexible magnets are:

• Durable – They are straightforward to maintain and harmless for finished surfaces, containing no oils or plasticizers that could lead to cracking, drying, or surface issues when adequately cared for.
• Safe – The materials used are free of lead and barium, ensuring a non-toxic substrate safe for both workers and consumers.
• Machinable – They can be effortlessly drilled or cut with tools such as scissors, knives, dies, punches, routers, or flatbed cutters to fit various applications.
• Temperature Resistant – They endure limited temperature exposure between -15°F and 160°F (-26 to 71°C) without losing magnetism.
• Chemical Resistant – They are highly resistant to air, ozone, and steam, unaffected by substances like mineral oil, weak acids, lye, kerosene, or glycol but have slight vulnerabilities to nitric acid. Petrol, acetone, and alcohol (at 90%) may cause swelling, and they can dissolve in benzene and chlorinated solvents.

Chapter 2: What are Magnetizers, Magnetic Labels, and Magnetic Paper?

This chapter comprehensively explores magnetizers, magnetic labels, and magnetic paper, detailing their uses, applications, and differences. Learn more about how magnetization technologies and flexible magnetic products are shaping the labeling, signage, and printing industries.

Their adaptability makes them a vital resource in retail operations, office organization, and equipment manufacturing.

Adhesive Magnetic Tape

Self-adhesive flexible magnetic tape features a permanent magnetic surface on one side and a strong, easy-peel self-adhesive coating on the other. This product, commonly referred to as magnetic tape or magnetic mounting tape, is extensively used in commercial displays, retail merchandising, exhibition graphics, and DIY projects.

This versatile tape provides a convenient solution for mounting photos, signs, posters, bills, or lightweight promotional materials on non-metallic surfaces. It is often leveraged for magnetic closures, document holders, and as a mounting solution for point-of-sale advertising. Two primary magnetic tape polarities—Type A and Type B—must be paired in applications where mutual attraction is necessary.

In addition to traditional magnetic tape, self-adhesive ferrous and steel tapes are used to convert non-magnetic surfaces to magnet-friendly backgrounds for flexible magnetic products. It is important to test large-scale applications, as surface conditions significantly affect tape or adhesive performance.

For best results during installation, the mounting surface should be meticulously clean, dry, and free of dust or oil. Use a suitable cleaning agent and let the area dry before application. Smooth, flat substrates—such as glass, high-density cardboard, or unvarnished wood—optimize adhesive contact, while rough or porous surfaces may reduce bond strength. To maximize adhesive lifespan, avoid touching the adhesive after removing the protective film and apply immediately.

Examples of compatible surfaces for self-adhesive neodymium or flexible magnets include:

• Uncoated gray cardboard or chipboard
• White laminated or carpeted cardboard
• Laser printer paper and labels
• Acrylic glass (PMMA)
• Smooth, untreated woods

Pressing and Drying the Adhesive

To achieve sustainable magnetic bonding, apply uniform pressure along the entire length of the tape or magnet strip after positioning. Allow adhesives to cure for at least 72 hours for full-strength bonding before subjecting the material to heavy use, load, or stress.

The recommended environmental temperature range for optimal adhesive curing is between 69.8°F and 100.4°F (21°C to 38°C). Exposing adhesives to temperatures higher than 176°F (80°C) or prolonged UV exposure can degrade performance and reduce holding strength over time. Similarly, humidity can impact long-term bond integrity, so consider both indoor and outdoor conditions when choosing magnetic tape or magnets for permanent installations.

Self-adhesive magnetic products have an inherent service life based on adhesive type and application environment:

• Adhesive film-backed magnets: approximately 12 months
• Foam-backed adhesive magnets: approximately 18 months
• Tenacious tape magnetic strips: approximately 6 months

Keep in mind that these estimates are guidelines. Actual adhesive lifespans may vary depending on surface type, exposure to sunlight, humidity, and tension. With ideal application and minimal exposure to environmental stressors, some adhesives can retain holding power significantly longer.

Characteristics of Self-adhesive Magnets

Premium adhesive backing ensures superior initial tack, long-term adhesion, and enhanced magnetic holding force for both light-duty and industrial applications. Features like quick-release tabs speed up liner removal during installation while robust neodymium or flexible ferrite materials deliver maximum magnetic strength and reliability for magnetic closures, attachment, or display systems.
