Rubber/Flexible Magnets

Brief introduction of rubber magnets(magnetic rubber):

Rubber magnets sometimes called magnetic rubber. Magnetic rubber itself has no magnetism , the magnetism comes from filled magnetic powder. So the magnetic powder is obligate material for produce magnetic rubber. Magnetic additive can be divided into metal magnetic powder, Fe-Co powder, Fe-Ni powder and Fe-Ba powder. Fe-Co powder is the most widely used. Metal magnetic powder is seldom used because of the expensive cost. At the present, the Fe-O powder mostly used, they are ferric oxide and two valence metal compounds, although is the same ferrite magnetic powder, the ultimate magnetic strength are not the same because of the different crystal habit,particle size, and uniformity. In fact, rubber magnet belong to ferrite magnet series, it is the magnet composed of bond ferrite magnet powder and synthetic rubber, made out by extrusion molding and injection molding, and it can be distorted. Rubber magnets can be machined into rubber magnetic strips, rubber magnetic rolls, rubber magnetic sheets and other different shapes.

Rubber magnet belong to ferrite magnetic materials series, it is made from ferrite magnes powder and rubber by extruding or injecting. It has properties of soft, resilience and twisable. Just because of these properties,it also called flexible magnets. It’s maximum energy is 0.60~1.50 MGOe。

Manufacturing process of rubber magnets(magnetic rubber):

The manufacturing process of magnetic rubber is much the same as other products. At first, determine the variety,particle size and dosage of magnetic powder. Then determine the rubber kinds according to application of rubber magnets. For example, natural rubber needed for wear resistant rubber magnets. The magnetization process need to be added when vulcanize it, which give the products permanent magnetism. The advantage for magnetize it before vulcanizing is external magnetic field not changed and pass the rubber network easily;The passing ability of magnetic field is bad for magnetize it after vulcanizing, but it is easy to operate .

The physical quantity used to represent magnetism of rubber magnets are magnetic induction strength, remanence , and maximum energy etc. Magnetic induction strength is most commonly used, the value of which is required to be 100-600GS.

Rubber magnets made of magnetic powder(SrO6、Fe2O3),(CPE)and other additive(EBSO、DOP),and made out by extruding or calendering. Rubber magnets can be devided intoisotropic rubber magnetand anisotropic rubber magnets . It can be machined into rubber magnetic strips, rubber magnetic rolls, rubber magnetic sheets and other different shapes. The maximum energy of rubber magnet is 0.60-1.50 MGOe. The surface of rubber magnet can be covered with PVC,coated paper,adhesive.

Production process of rubber magnets:

ingredient→mixture→extruding/calendering /injecting → machining →magnetizing →inspecting(appearance,size,magnetism,hardness,density, ageing resistance etc) → packing

The application of rubber magnets:

The door sealing strip is on behalf of the traditional application of rubber magnets. With the development of high-tech and household electrical appliance, rubber magnets get more widely used.The main application field of rubber magnets are micro-motors,door sealing for kinds of electrical appliances and advertisement.

Rubber magnets can be machined into magnetic strips, magnetic rolls, magnetic sheet ,magnetic tapes and kinds of shapes. The surface of rubber magnets can be covered with PVC,adhesive,copper-plate paper and can be cut into different shapes. The most common application of rubber magnets is refrigerator magnets.
