The one concept that best describes rubber coated magnets is: it's a perfect combination of force and protection. Rubber covered magnets are actually one extension of pot magnet using the same working principle, but the rubber coating has greatly broadened the application scope of pot magnet.
It doesn't happen when you need to hold something on a nice, elegant surface, you do with your greatest tenderness not to leave any scratch on it and this is why rubber coated super magnet is invented. Rubber coating can effectively avoid direct contact of the surface with sharp, hard objects minimizing the cause of scratch.
Basically you can use them anywhere you want as long as they hold. The uniqueness of its rubber coating makes them more suitable for delicate surface than other magnetic products. TPV has superior chemical stabilities but using it in places where it is too hot, too cold or corrosive may compromise its life.
The material we use for rubber coated magnets is TPV which features better durability than regular rubber due to its more stabilized chemical properties. You do not need to worry about its becoming hardened or peeling off in a long time.
What’s more, odorlessness is another benefit, which differentiates TPV from regular rubber. TPV does not stain --- try to use them with your bare hand for a while and TPV won’t leave any black mark on your fingers.
It is true that rubber coating does not contribute to a better force, instead it reduces the holding force of the part. However, by following some approaches you still get wanted force with these rubber coated super magnets. Simply put, a rubber coating of even thickness and an optimized structure will promote the holding force, which is exactly what we are using with our rubber coated magnets.
Rubber coated Neodymium magnets give great durability and high friction. The rubber coating acts as a protection for the Neodymium Magnet inside against chipping and exposure to liquids. Rubber coated neodymium magnets are used in many holding applications especially when it is on a delicate surface.
Generally speaking, the fridge magnets you buy from gift or souvenir shops will have a flexible rubber or ferrite magnet on the back. Both types of magnets are great value for money while not as strong as neodymium magnets, they are more than strong enough to hold a lightweight item to a fridge. Both are flexible rubber and ferrite magnets are available with self-adhesive on one side and are great for making your own rubber fridge magnets.
A4: As the magnet is completely covered by rubber coating, rubber coated super magnets are water-proof as well as incredibly resistant to damage. Also the rubberised neodymium magnets is very durable and will not easily break like a normal magnet. Rubber coated neodymium magnets give great durability and high friction to keep them from slipping on surfaces.
Magnets can be machined. However, hard magnet materials – as opposed to the flexible or rubber covered magnets materials- are extremely difficult to machine. Magnets should be machined using diamond tools or soft grinding wheels, and in the un-magnetized state as far as possible. In general, it is best not to try and machine hard magnet materials unless you are familiar with these specialized machining techniques.
