Magnetic plastics can be divided into structural type and composite type according to their composition. Structural magnetic plastics refer to the magnets with strong magnetism of polymer itself; Composite magnetic plastics refer to the addition of magnetic powder and other additives in plastics or rubber matrix. Magnetic fillers can be divided into ferrite type, rare earth type and nanocrystalline magnetic type. According to the difference of magnetic properties in different directions, magnetic fillers can also be divided into isotropy and anisotropy. The main advantages of magnetic plastics are: low density, high impact strength, cutting, drilling, welding, laminating and embossing, etc., without fragmentation. It can be processed by general plastic processing methods (such as injection, die pressing, extrusion, etc.), and can be processed into products with high dimensional accuracy, thin wall and complex shape, and can be formed with inserts. The products can obtain the comprehensive properties of magnetic properties and mechanical, optical and electrical properties, and realize the miniaturization, lightweight, precision and high performance of electromagnetic equipment.

Magnetic plastics is the process of transforming traditional sintering magnet into ordinary plastic forming method. It uses less energy and has higher output. At the same time, it meets the requirements of light weight, miniaturization, high precision and complex product model of magnetic products, so that magnetic products can be designed with the same degree of freedom as plastic products. NFD magnetic product series includes many types of magnetic fillers and matrix resins, which meet different working conditions and have high design flexibility.

The magnetic filler is composed of magnetic powder, resin and additives. The resin acts as bonding magnetic powder. The magnetic filler is generally ferrite magnetic powder and rare earth permanent magnetic powder.

Magnetic plastics are mainly divided into two categories, one is isotropic magnet plastics with low performance, and the magnetization direction of magnetic particles is irregular; the other is anisotropic magnet plastics with strong performance, and the magnetization direction of magnetic particles is ordered.

NFD adds high proportion magnetic powder to plastic matrix through professional technology. Compared with ordinary magnetic plastic products, NFD has stronger magnetism and excellent mechanical and physical properties, while maintaining good processing performance in material forming process.

Characteristics of magnetic plastics:

1. Low density.

2. Shock resistance, not easy to break.

3. Using ordinary plastic injection, moulding and extrusion processing methods, thin-walled and complex magnet plastics can be formed with high processing accuracy, and drilling, cutting, embossing and welding operations can also be carried out on magnet plastics.
