Flexible Rubber Magnets: A Versatile and Affordable Solution
Flexible rubber magnets are a magnetic material that offers versatility and affordability for a wide range of applications. These magnets are made by mixing ferrite magnet powder and rubber polymer resin, which are then pressed or rolled to create the final product. While they are not as strong as traditional magnetic materials like neodymium or samarium cobalt, their flexibility and low cost make them a popular choice for various industries.
One of the most significant advantages of flexible rubber magnets is their flexibility. Unlike other magnetic materials, they can be easily bent, twisted, and cut to fit different shapes and sizes, making them ideal for applications that require conformability. The ability to be molded into any shape or size without losing their magnetic energy makes them a popular choice for promotional items, educational materials, and signage.
Flexible magnets come in strips, sheetings, or rolls and can be custom cut, slit, or scored to meet specific requirements. The material is part of the permanent magnet family and can be easily manipulated, bent, twisted, coiled, cut, printed, silk-screened, or painted on with permanent or erasable markers. They can also easily adhere to other items.
While flexible magnets are not as durable as heavier magnets, they can offer higher energy products with energy ranges from 0.6 MGOe to 1.6 MGOe. They can replace ceramic materials in applications where close tolerances are not necessary and operating temperatures are below 80°C. Their low cost and ease of use make them a popular choice for various industries such as automotive, advertising, and educational materials.
At our company, we offer a range of finishes and adhesive backings designed for indoor or outdoor applications. We understand that selecting the right adhesive is critical to product function and can provide several options to work with various materials and conditions. Our magnets come with almost any type of adhesive available, including foam and permanent or removable adhesive.
In conclusion, flexible rubber magnets are an affordable and versatile magnetic material suitable for various applications. They offer a unique combination of flexibility, cost-effectiveness, and easy manipulation that allows for design innovations and automated manufacturing techniques not possible with rigid or brittle materials.

Production Process of Flexible Rubber Magnets
Materials Inspection
Crushing
The production process of flexible rubber magnets begins with mixing the magnetic powder with a polymer matrix, such as rubber, using a compounding machine. The mixed material is then passed through a calendering machine, where it is flattened to the desired thickness.
Afterward, the magnet sheet is magnetized by passing it through a strong magnetic field in the direction of its thickness. The magnetized sheet is then cut into the desired shape using a die cutter or knife cutter.
The next step is to cure the magnet to enhance its magnetic properties. The magnet is heated in a continuous curing oven at a specific temperature and duration, depending on the type of magnet.
Once the magnet has cured, it is coated with a protective layer to enhance its durability and resistance to water and other environmental factors. The coating material is applied using a roller or spraying machine, and the magnet is passed through an oven for the final curing process.
Finally, the flexible rubber magnet is inspected for quality and packaged for shipment. The inspection process involves checking the thickness, magnetic strength, and overall quality of the magnet.
In conclusion, the production process of flexible rubber magnets involves mixing magnetic powder and rubber, calendering, magnetizing, curing, coating, and quality inspection. This process produces high-quality magnets with excellent magnetic properties, durability, and resistance to environmental factors. If you’re looking for a reliable and versatile magnet for your application, flexible rubber magnets are an excellent choice.
