After processing, the shape is flexible, elastic, and bendable, and the shape can be trimmed according to the required size, and it can also be covered with PVC, adhesive, and UV oil according to customer specific requirements.
Its performance testing generally includes appearance, size, magnetic properties, magnetic polarity, hardness, specific gravity, tensile strength, aging resistance, rotation performance.
Its advantages are on its good consistency, high dimensional accuracy; good impact and vibration resistance, not easy to break; small gravity which is conducive to the lightweight of the device and the whole machine; it can be manufactured into a magnet with full radial (full radiation) orientation, and it can be produced with different shapes magnets such as long and thin shapes, and when post-processing such as blanking, cutoff, punching and bending can be easily performed.
Its disadvantage is that the magnetism is very weak, and the magnetic force begins to decline at 100°C, besides, the rubber magnet contains a lot of metal substances such as neodymium and iron, which will be corroded and rusted in the air, and the temperature characteristics are relatively poor, and it is easy to be pulverized.
It is mainly used in Tight seals on refrigerator doors, disinfection cabinets, kitchen cabinets, toys, stationery, advertisements, computer cooling fan motors, air-conditioning air supply motors, printer drive motors, VCD and DVD drive motors, brushless DC wind (hanging) fans, magnetic Door seals, decorations, health care magnetic mattresses, magnetic rodsMagnetic provisional driver sign for passenger vehicles,Curing installations for elevators (practically all elevators use curing sheets), Stationery and novelty goods (ideal for public relation items).
