ISO 9000 PVC Coating 300GS To1200GS Rubber Ferrite Magnets
Rubber Ferrite Magnets
Rubber ferrite is a magnetic material mixed with rubber and ferrite
magnetic powder to protect against scratches, impacts, moisture,
and other harsh environments. At the same time, because of its low
price of raw materials and good anti-rust characteristics, it is
widely used in daily households, bathrooms, fan motors.
These magnets can withstand operating temperatures up to 90°C and
long-term operation in humid environments, and offer soft bending
resistance.

Classification of Ferrite Magnets
According to the different production processes, ferrite magnets can be divided into sintered ferrite and bonded ferrite. Among them, sintered ferrites can be divided into dry pressed ferrites and wet pressed ferrites, and bonded ferrites can be divided into extruded ferrite, pressed ferrite and injection molded ferrite.
Ferrite magnets can be divided into isotropic permanent magnets and anisotropic permanent magnets according to whether an external magnetic field is applied during molding. Isotropic sintered ferrite permanent magnets are weakly magnetic, but can be magnetized in different directions of the magnet. Anisotropic ferrite permanent magnets are very magnetic but can only be magnetized in the intended magnetization direction of the magnet.
Soft, flexible, twistable magnets made from bonded ferrite powder and synthetic rubber are also called rubber magnets.
