Project Description

Magnets and rubber are two distinct materials that do not have a direct relationship with each other. However, they can be used together in different ways to achieve specific functions. For example, rubber can give magnetic products flexibility, and soft rubber can protect fragile neodymium iron boron magnets as well.

With our advanced manufacturing technology and expertise, China Magnets Source can tailor flexible neodymium magnets and rubber coated neodymium magnet.

Our rubber magnets are made of high-quality rubber and magnet powder, which provide strong magnetic properties and excellent flexibility. In addition, our rubber coated pot magnets can be designed to pull force requirement and ensure their longevity and durability.

Powerful, Waterproof & Scratch Protection - Flexible Magnetic Sheet Rolls, Rubber Coated Neodymium Magnets


Flexible magnet, also known as magnet sheet, magnet roll, is a type of permanent magnet made of a mixture of magnetic powder (such as ferrite, neodymium, SmFeN) and a flexible plastic or rubber binder. This composition allows the magnet to be easily bent, twisted, and cut into different shapes and sizes without losing its magnetic properties.

Flexible magnets are often used for a variety of applications, such as in advertising magnets, refrigerator magnets, automotive signs, and industrial magnets. They are also commonly used in educational settings to teach magnetism and in crafts projects. Flexible magnets are known for their versatility, durability, and low cost compared to other types of magnets.

Flexible NdFeB is made by mixing neodymium powder with a flexible plastic or rubber binder. They are usually stronger than flexible ferrite magnets and can be used for applications requiring higher magnetic power.

Flexible ferrite, on the other hand, is made by mixing a ferrite powder with a flexible plastic or rubber binder. They are usually less expensive and have a weaker magnetic force and can be used for fridge magnets and car magnets.


  • Are magnets waterproof or how to waterproof a magnet?
  • How to keep neodymium magnets from breaking?
  • Can neodymium magnets rust?

If you have the same problem with NdFeB magnets, then you might consider trying rubber coated magnets.

Rubber covered magnet is permanent neodymium magnet that have a rubber coating or casing around them. The rubber covering provides protection to the magnet from damage, corrosion, and scratches, and it also helps to improve the grip of the magnet. Strong and durable, they provide an easy, non-permanent way to hold objects in place without the need for screws or other fasteners.


Powerful – It uses the strongest magnetic material like sintered neodymium magnet to make sure attraction force as strong as possible. The maximum adhesive force of these magnets is slightly lower compared to similar-sized neodymium magnets without coating, but it’s still very strong.

Rust-proof – Multiple coating of NiCuNi+rubber keeps neodymium magnet away from all kinds of rusting factors.

Waterproof – It uses rubber seal and can be used outdoors and in wet surroundings.

Durable – Rubber coating with a certain thickness is flexible; it can protect brittle permanent magnet in case of collision.

Scratch protection – Delicate surfaces, such as whiteboards, painted surface or magnetic glass boards, are well protected.

Friction – The rubber coat substantially increases the magnetic adhesive force in shear direction. So when mounting objects to a vertical surface (i.e., a steel wall), these magnets are great for holding up objects without super strong magnetic strength.


Rubber-coated magnets can be used for many purposes, such as mounting, holding, gripping, or clamping applications, and are designed with a central threaded hole or stud for added convenience.

These magnets are available in various shapes and sizes and can be tailored to meet specific needs, making them a popular choice across industries to daily life. For instance, the automotive industry employs them to secure car signs or lights, while the industrial sector utilizes them to hold metal sheets, tools, or other items. The medical field also employs rubber-coated magnets in magnetic therapy, which aids in reducing pain and promoting healing.

We also make other mouting magnets, like pot magnet, 3M adhesive magnet and color pin magnet. You can choose based on your application.
