The plastic magnets are molding materials which produced by injection mould process that they can be directly molded into other assembly components. Its main composition includes ferrite magnetic powder, plastic resin, rare earth metal powder, and other subordinate materials. Furthermore, the plastic magnets are the first magnetic polymer that can fully function at the room temperature so as to benefit commercial usages.
These plastic magnets from Magtech Magnetic Products Corp. are classified as non-metallic one which was created by researchers at the University of Durham leading to a new gate of magnetic materials applications. During injection process, the powder is oriented by magnetic field, we call this material is anisotropic magnet; on the contrary, we call it as isotropic magnet.
The magnetic power of plastic magnet is between isotropic ferrite and anisotropic ferrite. However, they have a high precise dimension yet durable. Having stable state in the air and high density, these magnets can used for several applications such as computer hardware, medical devices, etc.
