Rubber NdFeB

2019-12-05

Product description

Rubber neodymium-iron-boron products are mixed with rubber and bonded neodymium-iron-boron magnetic powder, and processed through a series of processes such as compaction and rolling to form high-performance, thin-thickness products of various sizes. Widely used in various electronic appliances, instruments and medical care and other fields.


Features

1. Made of NdFeB magnetic powder mixed rubber.

2. The processing methods include rolled rolls and extruded magnetic strips, but the density of NdFeB magnetic powder is limited, and the products are mainly magnetic strips.

3. The isotropic rubber magnet can be designed for multi-pole magnetization.

4. The working environment temperature is about -40 ℃ -80 ℃.

5. Products are widely used in small motors, sensors, cooling fans, motor rotors, office OA equipment, stationery suction, advertising marketing accessories and refrigerator door seals.
